    I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
    \n
    What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
    \n
    I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
    \n
    I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
    \n
    I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
    \n
    The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
    \n
    `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
    \n
    Which gives me a list of movies of which this is an example:\n
    \n
    `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
    \n
    Then I used sed with the expression groups to remove:\n
    \n
    - the leading forward slash\n
    - Everything from `.[` to the end\n
    - All of the periods in between words\n
    \n
    And the last expression checks for one or more spaces and replaces them with a single space.\n
    \n
    This is the full sed command:\n

    `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&-]/ /g; s/ +/ /g’ movielist`\n
    \n
    Which leaves me with a pretty list of movies that looks like this:\n
    \n
    `The Hunger Games (2012)`\n
    \n
    I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

  +title: "My First Regular Expressions"
  +url: null
  +body: """
    I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
    \n
    What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
    \n
    I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
    \n
    I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
    \n
    I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
    \n
    The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
    \n
    `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
    \n
    Which gives me a list of movies of which this is an example:\n
    \n
    `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
    \n
    Then I used sed with the expression groups to remove:\n
    \n
    - the leading forward slash\n
    - Everything from `.[` to the end\n
    - All of the periods in between words\n
    \n
    And the last expression checks for one or more spaces and replaces them with a single space.\n
    \n
    This is the full sed command:\n
    \n
    `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&-]/ /g; s/ +/ /g’ movielist`\n
    \n
    Which leaves me with a pretty list of movies that looks like this:\n
    \n
    `The Hunger Games (2012)`\n
    \n
    I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
    \n
    Edit: fixed title so it didn’t say “regex expressions”

      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

    It is a great book, although a bit outdated. In particular, nowadays `egrep` is not recommended to use. `grep -E` is a more portable synonim.\n
    \n
    Some notes on you script:\n
    \n
    1. You don’t need to escape slashes in grep regex. In the sed `s///` command better use another character like `s###` so you also can leave slashes unescaped.\n
    2. You usually don’t need to pipe `grep` and `sed`, `sed -n` with regex address and explicit printing command gives the same result as `grep`.\n
    3. You could omit leading slash in your `egrep` regex, so you won’t need to remove it later.\n
    \n
    So I would do the same with\n

      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

      It is a great book, although a bit outdated. In particular, nowadays `egrep` is not recommended to use. `grep -E` is a more portable synonim.\n
      \n
      Some notes on you script:\n
      \n
      1. You don’t need to escape slashes in grep regex. In the sed `s///` command better use another character like `s###` so you also can leave slashes unescaped.\n
      2. You usually don’t need to pipe `grep` and `sed`, `sed -n` with regex address and explicit printing command gives the same result as `grep`.\n
      3. You could omit leading slash in your `egrep` regex, so you won’t need to remove it later.\n
      \n
      So I would do the same with\n
      \n

    \n
    Not directed at you personally, but this is the kind of pointless pedantry from upstream developers that grinds my gears.\n
    \n
    Like, I’ve used `egrep` for 25 years. I don’t know of a still relevant Unix variant in existence that doesn’t have the `egrep` command. But suddenly now, when any other Unix variant but Linux is all but extinct, and all your shell scripts are probably full of bashisms and Linuxisms anyway, *now* there is somehow a portability problem, and they deem it necessary to print out a warning whenever I dare to run `egrep` instead of `grep -E`? C’mon now … If anything, they have just made it *less* portable by spitting out spurious warnings where there weren’t any before.

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n

      It is a great book, although a bit outdated. In particular, nowadays `egrep` is not recommended to use. `grep -E` is a more portable synonim.\n
      \n
      Some notes on you script:\n
      \n
      1. You don’t need to escape slashes in grep regex. In the sed `s///` command better use another character like `s###` so you also can leave slashes unescaped.\n
      2. You usually don’t need to pipe `grep` and `sed`, `sed -n` with regex address and explicit printing command gives the same result as `grep`.\n
      3. You could omit leading slash in your `egrep` regex, so you won’t need to remove it later.\n
      \n
      So I would do the same with\n
      \n

    \n
    Not directed at you personally, but this is the kind of pointless pedantry from upstream developers that grinds my gears.\n
    \n
    Like, I’ve used `egrep` for 25 years. I don’t know of a still relevant Unix variant in existence that doesn’t have the `egrep` command. But suddenly now, when any other Unix variant but Linux is all but extinct, and all your shell scripts are probably full of bashisms and Linuxisms anyway, *now* there is somehow a portability problem, and they deem it necessary to print out a warning whenever I dare to run `egrep` instead of `grep -E`? C’mon now … If anything, they have just made it *less* portable by spitting out spurious warnings where there weren’t any before.

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

      \n
      Some notes on you script:\n
      \n
      1. You don’t need to escape slashes in grep regex. In the sed `s///` command better use another character like `s###` so you also can leave slashes unescaped.\n
      2. You usually don’t need to pipe `grep` and `sed`, `sed -n` with regex address and explicit printing command gives the same result as `grep`.\n
      3. You could omit leading slash in your `egrep` regex, so you won’t need to remove it later.\n
      \n
      So I would do the same with\n

    \n
    Not directed at you personally, but this is the kind of pointless pedantry from upstream developers that grinds my gears.\n
    \n
    Like, I’ve used `egrep` for 25 years. I don’t know of a still relevant Unix variant in existence that doesn’t have the `egrep` command. But suddenly now, when any other Unix variant but Linux is all but extinct, and all your shell scripts are probably full of bashisms and Linuxisms anyway, *now* there is somehow a portability problem, and they deem it necessary to print out a warning whenever I dare to run `egrep` instead of `grep -E`? C’mon now … If anything, they have just made it *less* portable by spitting out spurious warnings where there weren’t any before.

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

        Some notes on you script:\n
        \n
        1. You don’t need to escape slashes in grep regex. In the sed `s///` command better use another character like `s###` so you also can leave slashes unescaped.\n
        2. You usually don’t need to pipe `grep` and `sed`, `sed -n` with regex address and explicit printing command gives the same result as `grep`.\n

      Not directed at you personally, but this is the kind of pointless pedantry from upstream developers that grinds my gears.\n
      \n
      Like, I’ve used `egrep` for 25 years. I don’t know of a still relevant Unix variant in existence that doesn’t have the `egrep` command. But suddenly now, when any other Unix variant but Linux is all but extinct, and all your shell scripts are probably full of bashisms and Linuxisms anyway, *now* there is somehow a portability problem, and they deem it necessary to print out a warning whenever I dare to run `egrep` instead of `grep -E`? C’mon now … If anything, they have just made it *less* portable by spitting out spurious warnings where there weren’t any before.

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

        It is a great book, although a bit outdated. In particular, nowadays `egrep` is not recommended to use. `grep -E` is a more portable synonim.\n
        \n
        Some notes on you script:\n
        \n
        1. You don’t need to escape slashes in grep regex. In the sed `s///` command better use another character like `s###` so you also can leave slashes unescaped.\n
        2. You usually don’t need to pipe `grep` and `sed`, `sed -n` with regex address and explicit printing command gives the same result as `grep`.\n
        3. You could omit leading slash in your `egrep` regex, so you won’t need to remove it later.\n
        \n
        So I would do the same with\n

      Not directed at you personally, but this is the kind of pointless pedantry from upstream developers that grinds my gears.\n
      \n
      Like, I’ve used `egrep` for 25 years. I don’t know of a still relevant Unix variant in existence that doesn’t have the `egrep` command. But suddenly now, when any other Unix variant but Linux is all but extinct, and all your shell scripts are probably full of bashisms and Linuxisms anyway, *now* there is somehow a portability problem, and they deem it necessary to print out a warning whenever I dare to run `egrep` instead of `grep -E`? C’mon now … If anything, they have just made it *less* portable by spitting out spurious warnings where there weren’t any before.

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

        It is a great book, although a bit outdated. In particular, nowadays `egrep` is not recommended to use. `grep -E` is a more portable synonim.\n
        \n
        Some notes on you script:\n
        \n
        1. You don’t need to escape slashes in grep regex. In the sed `s///` command better use another character like `s###` so you also can leave slashes unescaped.\n
        2. You usually don’t need to pipe `grep` and `sed`, `sed -n` with regex address and explicit printing command gives the same result as `grep`.\n
        3. You could omit leading slash in your `egrep` regex, so you won’t need to remove it later.\n
        \n
        So I would do the same with\n

      Not directed at you personally, but this is the kind of pointless pedantry from upstream developers that grinds my gears.\n
      \n
      Like, I’ve used `egrep` for 25 years. I don’t know of a still relevant Unix variant in existence that doesn’t have the `egrep` command. But suddenly now, when any other Unix variant but Linux is all but extinct, and all your shell scripts are probably full of bashisms and Linuxisms anyway, *now* there is somehow a portability problem, and they deem it necessary to print out a warning whenever I dare to run `egrep` instead of `grep -E`? C’mon now … If anything, they have just made it *less* portable by spitting out spurious warnings where there weren’t any before.

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

          It is a great book, although a bit outdated. In particular, nowadays `egrep` is not recommended to use. `grep -E` is a more portable synonim.\n
          \n
          Some notes on you script:\n
          \n
          1. You don’t need to escape slashes in grep regex. In the sed `s///` command better use another character like `s###` so you also can leave slashes unescaped.\n
          2. You usually don’t need to pipe `grep` and `sed`, `sed -n` with regex address and explicit printing command gives the same result as `grep`.\n
          3. You could omit leading slash in your `egrep` regex, so you won’t need to remove it later.\n
          \n
          So I would do the same with\n

        Not directed at you personally, but this is the kind of pointless pedantry from upstream developers that grinds my gears.\n
        \n
        Like, I’ve used `egrep` for 25 years. I don’t know of a still relevant Unix variant in existence that doesn’t have the `egrep` command. But suddenly now, when any other Unix variant but Linux is all but extinct, and all your shell scripts are probably full of bashisms and Linuxisms anyway, *now* there is somehow a portability problem, and they deem it necessary to print out a warning whenever I dare to run `egrep` instead of `grep -E`? C’mon now … If anything, they have just made it *less* portable by spitting out spurious warnings where there weren’t any before.

    > GNU grep, the most widespread implementation, does not include egrep, fgrep and rgrep for years. Distributions (not all, but many) provide shell scripts that simply run grep with corresponding option for backward compatibility. You can learn this from official documentation.\n
    \n
    It seems you need to read the official documentation yourself. While it’s new information to me that `egrep` is no longer a symlink, as it used to be a couple of years ago, but a shell script wrapper to `grep -E` instead, the egrep command is to this day still provided by upstream GNU grep and is installed by default if you run `./configure; make; make install` from source. So it is not a backward compatibility hack provided by the distribution.\n
    \n
    You can check for yourself. Download the source from [ftp.gnu.org/gnu/grep/grep-3.11.tar.gz](https://ftp.gnu.org/gnu/grep/grep-3.11.tar.gz), unpack and look for `src/egrep.sh` or line 1756 of `src/Makefile`. Apparently the change from symlink to shell script was done in 2014, and the deprecation warning was added only last year.\n
    \n
    In any case, my larger point is that the depreciation of `egrep` was a pointless and arbitrary decision that does not benefit users, especially not veterans like myself who have become accustomed to its presence. I don’t mind change, but let’s be honest, most people are not in the habit of checking the minutiae of every little command line utility they use, so a change like this violates the principle of least surprise. It’s one thing if things are changed with a good reason and the users do not only suffer the inconvenience of the change but get to reap the benefits of it as well, but so far I haven’t found any justification for it yet, nor can I think of any.\n
    \n
    So if there is a portability problem with using `egrep` now, it’s a *self-inflicted* portability problem that they caused by deprecating `egrep` in the first place.\n
    \n
    > Also, my scripts are not full of bashisms, gnuisms, linuxisms and other -isms, I try to keep them portable unless it is really necessary to use some unportable command or syntax.\n
    \n
    Good for you. Do you want a cookie or something?

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n

      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

          Some notes on you script:\n
          \n
          1. You don’t need to escape slashes in grep regex. In the sed `s///` command better use another character like `s###` so you also can leave slashes unescaped.\n
          2. You usually don’t need to pipe `grep` and `sed`, `sed -n` with regex address and explicit printing command gives the same result as `grep`.\n
          3. You could omit leading slash in your `egrep` regex, so you won’t need to remove it later.\n

        Not directed at you personally, but this is the kind of pointless pedantry from upstream developers that grinds my gears.\n
        \n
        Like, I’ve used `egrep` for 25 years. I don’t know of a still relevant Unix variant in existence that doesn’t have the `egrep` command. But suddenly now, when any other Unix variant but Linux is all but extinct, and all your shell scripts are probably full of bashisms and Linuxisms anyway, *now* there is somehow a portability problem, and they deem it necessary to print out a warning whenever I dare to run `egrep` instead of `grep -E`? C’mon now … If anything, they have just made it *less* portable by spitting out spurious warnings where there weren’t any before.

    > GNU grep, the most widespread implementation, does not include egrep, fgrep and rgrep for years. Distributions (not all, but many) provide shell scripts that simply run grep with corresponding option for backward compatibility. You can learn this from official documentation.\n
    \n
    It seems you need to read the official documentation yourself. While it’s new information to me that `egrep` is no longer a symlink, as it used to be a couple of years ago, but a shell script wrapper to `grep -E` instead, the egrep command is to this day still provided by upstream GNU grep and is installed by default if you run `./configure; make; make install` from source. So it is not a backward compatibility hack provided by the distribution.\n
    \n
    You can check for yourself. Download the source from [ftp.gnu.org/gnu/grep/grep-3.11.tar.gz](https://ftp.gnu.org/gnu/grep/grep-3.11.tar.gz), unpack and look for `src/egrep.sh` or line 1756 of `src/Makefile`. Apparently the change from symlink to shell script was done in 2014, and the deprecation warning was added only last year.\n
    \n
    In any case, my larger point is that the depreciation of `egrep` was a pointless and arbitrary decision that does not benefit users, especially not veterans like myself who have become accustomed to its presence. I don’t mind change, but let’s be honest, most people are not in the habit of checking the minutiae of every little command line utility they use, so a change like this violates the principle of least surprise. It’s one thing if things are changed with a good reason and the users do not only suffer the inconvenience of the change but get to reap the benefits of it as well, but so far I haven’t found any justification for it yet, nor can I think of any.\n
    \n
    So if there is a portability problem with using `egrep` now, it’s a *self-inflicted* portability problem that they caused by deprecating `egrep` in the first place.\n
    \n
    > Also, my scripts are not full of bashisms, gnuisms, linuxisms and other -isms, I try to keep them portable unless it is really necessary to use some unportable command or syntax.\n
    \n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n

    +slug: "My-First-Regular-Expressions"
    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

          It is a great book, although a bit outdated. In particular, nowadays `egrep` is not recommended to use. `grep -E` is a more portable synonim.\n
          \n
          Some notes on you script:\n
          \n
          1. You don’t need to escape slashes in grep regex. In the sed `s///` command better use another character like `s###` so you also can leave slashes unescaped.\n
          2. You usually don’t need to pipe `grep` and `sed`, `sed -n` with regex address and explicit printing command gives the same result as `grep`.\n
          3. You could omit leading slash in your `egrep` regex, so you won’t need to remove it later.\n

        Not directed at you personally, but this is the kind of pointless pedantry from upstream developers that grinds my gears.\n
        \n
        Like, I’ve used `egrep` for 25 years. I don’t know of a still relevant Unix variant in existence that doesn’t have the `egrep` command. But suddenly now, when any other Unix variant but Linux is all but extinct, and all your shell scripts are probably full of bashisms and Linuxisms anyway, *now* there is somehow a portability problem, and they deem it necessary to print out a warning whenever I dare to run `egrep` instead of `grep -E`? C’mon now … If anything, they have just made it *less* portable by spitting out spurious warnings where there weren’t any before.

    > GNU grep, the most widespread implementation, does not include egrep, fgrep and rgrep for years. Distributions (not all, but many) provide shell scripts that simply run grep with corresponding option for backward compatibility. You can learn this from official documentation.\n
    \n
    It seems you need to read the official documentation yourself. While it’s new information to me that `egrep` is no longer a symlink, as it used to be a couple of years ago, but a shell script wrapper to `grep -E` instead, the egrep command is to this day still provided by upstream GNU grep and is installed by default if you run `./configure; make; make install` from source. So it is not a backward compatibility hack provided by the distribution.\n
    \n
    You can check for yourself. Download the source from [ftp.gnu.org/gnu/grep/grep-3.11.tar.gz](https://ftp.gnu.org/gnu/grep/grep-3.11.tar.gz), unpack and look for `src/egrep.sh` or line 1756 of `src/Makefile`. Apparently the change from symlink to shell script was done in 2014, and the deprecation warning was added only last year.\n
    \n
    In any case, my larger point is that the depreciation of `egrep` was a pointless and arbitrary decision that does not benefit users, especially not veterans like myself who have become accustomed to its presence. I don’t mind change, but let’s be honest, most people are not in the habit of checking the minutiae of every little command line utility they use, so a change like this violates the principle of least surprise. It’s one thing if things are changed with a good reason and the users do not only suffer the inconvenience of the change but get to reap the benefits of it as well, but so far I haven’t found any justification for it yet, nor can I think of any.\n
    \n
    So if there is a portability problem with using `egrep` now, it’s a *self-inflicted* portability problem that they caused by deprecating `egrep` in the first place.\n
    \n
    > Also, my scripts are not full of bashisms, gnuisms, linuxisms and other -isms, I try to keep them portable unless it is really necessary to use some unportable command or syntax.\n
    \n
    Good for you. Do you want a cookie or something?

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n

    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

            It is a great book, although a bit outdated. In particular, nowadays `egrep` is not recommended to use. `grep -E` is a more portable synonim.\n
            \n
            Some notes on you script:\n
            \n
            1. You don’t need to escape slashes in grep regex. In the sed `s///` command better use another character like `s###` so you also can leave slashes unescaped.\n
            2. You usually don’t need to pipe `grep` and `sed`, `sed -n` with regex address and explicit printing command gives the same result as `grep`.\n
            3. You could omit leading slash in your `egrep` regex, so you won’t need to remove it later.\n
            \n

          Not directed at you personally, but this is the kind of pointless pedantry from upstream developers that grinds my gears.\n
          \n
          Like, I’ve used `egrep` for 25 years. I don’t know of a still relevant Unix variant in existence that doesn’t have the `egrep` command. But suddenly now, when any other Unix variant but Linux is all but extinct, and all your shell scripts are probably full of bashisms and Linuxisms anyway, *now* there is somehow a portability problem, and they deem it necessary to print out a warning whenever I dare to run `egrep` instead of `grep -E`? C’mon now … If anything, they have just made it *less* portable by spitting out spurious warnings where there weren’t any before.

      > GNU grep, the most widespread implementation, does not include egrep, fgrep and rgrep for years. Distributions (not all, but many) provide shell scripts that simply run grep with corresponding option for backward compatibility. You can learn this from official documentation.\n
      \n
      It seems you need to read the official documentation yourself. While it’s new information to me that `egrep` is no longer a symlink, as it used to be a couple of years ago, but a shell script wrapper to `grep -E` instead, the egrep command is to this day still provided by upstream GNU grep and is installed by default if you run `./configure; make; make install` from source. So it is not a backward compatibility hack provided by the distribution.\n
      \n
      You can check for yourself. Download the source from [ftp.gnu.org/gnu/grep/grep-3.11.tar.gz](https://ftp.gnu.org/gnu/grep/grep-3.11.tar.gz), unpack and look for `src/egrep.sh` or line 1756 of `src/Makefile`. Apparently the change from symlink to shell script was done in 2014, and the deprecation warning was added only last year.\n
      \n
      In any case, my larger point is that the depreciation of `egrep` was a pointless and arbitrary decision that does not benefit users, especially not veterans like myself who have become accustomed to its presence. I don’t mind change, but let’s be honest, most people are not in the habit of checking the minutiae of every little command line utility they use, so a change like this violates the principle of least surprise. It’s one thing if things are changed with a good reason and the users do not only suffer the inconvenience of the change but get to reap the benefits of it as well, but so far I haven’t found any justification for it yet, nor can I think of any.\n
      \n
      So if there is a portability problem with using `egrep` now, it’s a *self-inflicted* portability problem that they caused by deprecating `egrep` in the first place.\n
      \n
      > Also, my scripts are not full of bashisms, gnuisms, linuxisms and other -isms, I try to keep them portable unless it is really necessary to use some unportable command or syntax.\n
      \n
      Good for you. Do you want a cookie or something?

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

            It is a great book, although a bit outdated. In particular, nowadays `egrep` is not recommended to use. `grep -E` is a more portable synonim.\n
            \n
            Some notes on you script:\n
            \n
            1. You don’t need to escape slashes in grep regex. In the sed `s///` command better use another character like `s###` so you also can leave slashes unescaped.\n
            2. You usually don’t need to pipe `grep` and `sed`, `sed -n` with regex address and explicit printing command gives the same result as `grep`.\n
            3. You could omit leading slash in your `egrep` regex, so you won’t need to remove it later.\n
            \n
            So I would do the same with\n

          Not directed at you personally, but this is the kind of pointless pedantry from upstream developers that grinds my gears.\n
          \n
          Like, I’ve used `egrep` for 25 years. I don’t know of a still relevant Unix variant in existence that doesn’t have the `egrep` command. But suddenly now, when any other Unix variant but Linux is all but extinct, and all your shell scripts are probably full of bashisms and Linuxisms anyway, *now* there is somehow a portability problem, and they deem it necessary to print out a warning whenever I dare to run `egrep` instead of `grep -E`? C’mon now … If anything, they have just made it *less* portable by spitting out spurious warnings where there weren’t any before.

      \n
      It seems you need to read the official documentation yourself. While it’s new information to me that `egrep` is no longer a symlink, as it used to be a couple of years ago, but a shell script wrapper to `grep -E` instead, the egrep command is to this day still provided by upstream GNU grep and is installed by default if you run `./configure; make; make install` from source. So it is not a backward compatibility hack provided by the distribution.\n
      \n
      You can check for yourself. Download the source from [ftp.gnu.org/gnu/grep/grep-3.11.tar.gz](https://ftp.gnu.org/gnu/grep/grep-3.11.tar.gz), unpack and look for `src/egrep.sh` or line 1756 of `src/Makefile`. Apparently the change from symlink to shell script was done in 2014, and the deprecation warning was added only last year.\n
      \n
      In any case, my larger point is that the depreciation of `egrep` was a pointless and arbitrary decision that does not benefit users, especially not veterans like myself who have become accustomed to its presence. I don’t mind change, but let’s be honest, most people are not in the habit of checking the minutiae of every little command line utility they use, so a change like this violates the principle of least surprise. It’s one thing if things are changed with a good reason and the users do not only suffer the inconvenience of the change but get to reap the benefits of it as well, but so far I haven’t found any justification for it yet, nor can I think of any.\n
      \n
      So if there is a portability problem with using `egrep` now, it’s a *self-inflicted* portability problem that they caused by deprecating `egrep` in the first place.\n
      \n
      > Also, my scripts are not full of bashisms, gnuisms, linuxisms and other -isms, I try to keep them portable unless it is really necessary to use some unportable command or syntax.\n

      Good for you. Do you want a cookie or something?

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n

    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

            It is a great book, although a bit outdated. In particular, nowadays `egrep` is not recommended to use. `grep -E` is a more portable synonim.\n
            \n
            Some notes on you script:\n
            \n
            1. You don’t need to escape slashes in grep regex. In the sed `s///` command better use another character like `s###` so you also can leave slashes unescaped.\n
            2. You usually don’t need to pipe `grep` and `sed`, `sed -n` with regex address and explicit printing command gives the same result as `grep`.\n
            3. You could omit leading slash in your `egrep` regex, so you won’t need to remove it later.\n
            \n

          Not directed at you personally, but this is the kind of pointless pedantry from upstream developers that grinds my gears.\n
          \n
          Like, I’ve used `egrep` for 25 years. I don’t know of a still relevant Unix variant in existence that doesn’t have the `egrep` command. But suddenly now, when any other Unix variant but Linux is all but extinct, and all your shell scripts are probably full of bashisms and Linuxisms anyway, *now* there is somehow a portability problem, and they deem it necessary to print out a warning whenever I dare to run `egrep` instead of `grep -E`? C’mon now … If anything, they have just made it *less* portable by spitting out spurious warnings where there weren’t any before.

      > GNU grep, the most widespread implementation, does not include egrep, fgrep and rgrep for years. Distributions (not all, but many) provide shell scripts that simply run grep with corresponding option for backward compatibility. You can learn this from official documentation.\n
      \n
      It seems you need to read the official documentation yourself. While it’s new information to me that `egrep` is no longer a symlink, as it used to be a couple of years ago, but a shell script wrapper to `grep -E` instead, the egrep command is to this day still provided by upstream GNU grep and is installed by default if you run `./configure; make; make install` from source. So it is not a backward compatibility hack provided by the distribution.\n
      \n
      You can check for yourself. Download the source from [ftp.gnu.org/gnu/grep/grep-3.11.tar.gz](https://ftp.gnu.org/gnu/grep/grep-3.11.tar.gz), unpack and look for `src/egrep.sh` or line 1756 of `src/Makefile`. Apparently the change from symlink to shell script was done in 2014, and the deprecation warning was added only last year.\n
      \n
      In any case, my larger point is that the depreciation of `egrep` was a pointless and arbitrary decision that does not benefit users, especially not veterans like myself who have become accustomed to its presence. I don’t mind change, but let’s be honest, most people are not in the habit of checking the minutiae of every little command line utility they use, so a change like this violates the principle of least surprise. It’s one thing if things are changed with a good reason and the users do not only suffer the inconvenience of the change but get to reap the benefits of it as well, but so far I haven’t found any justification for it yet, nor can I think of any.\n
      \n
      So if there is a portability problem with using `egrep` now, it’s a *self-inflicted* portability problem that they caused by deprecating `egrep` in the first place.\n
      \n
      > Also, my scripts are not full of bashisms, gnuisms, linuxisms and other -isms, I try to keep them portable unless it is really necessary to use some unportable command or syntax.\n
      \n
      Good for you. Do you want a cookie or something?

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

              It is a great book, although a bit outdated. In particular, nowadays `egrep` is not recommended to use. `grep -E` is a more portable synonim.\n
              \n
              Some notes on you script:\n
              \n
              1. You don’t need to escape slashes in grep regex. In the sed `s///` command better use another character like `s###` so you also can leave slashes unescaped.\n
              2. You usually don’t need to pipe `grep` and `sed`, `sed -n` with regex address and explicit printing command gives the same result as `grep`.\n
              3. You could omit leading slash in your `egrep` regex, so you won’t need to remove it later.\n
              \n

            Like, I’ve used `egrep` for 25 years. I don’t know of a still relevant Unix variant in existence that doesn’t have the `egrep` command. But suddenly now, when any other Unix variant but Linux is all but extinct, and all your shell scripts are probably full of bashisms and Linuxisms anyway, *now* there is somehow a portability problem, and they deem it necessary to print out a warning whenever I dare to run `egrep` instead of `grep -E`? C’mon now … If anything, they have just made it *less* portable by spitting out spurious warnings where there weren’t any before.

        > GNU grep, the most widespread implementation, does not include egrep, fgrep and rgrep for years. Distributions (not all, but many) provide shell scripts that simply run grep with corresponding option for backward compatibility. You can learn this from official documentation.\n
        \n
        It seems you need to read the official documentation yourself. While it’s new information to me that `egrep` is no longer a symlink, as it used to be a couple of years ago, but a shell script wrapper to `grep -E` instead, the egrep command is to this day still provided by upstream GNU grep and is installed by default if you run `./configure; make; make install` from source. So it is not a backward compatibility hack provided by the distribution.\n
        \n
        You can check for yourself. Download the source from [ftp.gnu.org/gnu/grep/grep-3.11.tar.gz](https://ftp.gnu.org/gnu/grep/grep-3.11.tar.gz), unpack and look for `src/egrep.sh` or line 1756 of `src/Makefile`. Apparently the change from symlink to shell script was done in 2014, and the deprecation warning was added only last year.\n
        \n
        In any case, my larger point is that the depreciation of `egrep` was a pointless and arbitrary decision that does not benefit users, especially not veterans like myself who have become accustomed to its presence. I don’t mind change, but let’s be honest, most people are not in the habit of checking the minutiae of every little command line utility they use, so a change like this violates the principle of least surprise. It’s one thing if things are changed with a good reason and the users do not only suffer the inconvenience of the change but get to reap the benefits of it as well, but so far I haven’t found any justification for it yet, nor can I think of any.\n
        \n
        So if there is a portability problem with using `egrep` now, it’s a *self-inflicted* portability problem that they caused by deprecating `egrep` in the first place.\n
        \n
        > Also, my scripts are not full of bashisms, gnuisms, linuxisms and other -isms, I try to keep them portable unless it is really necessary to use some unportable command or syntax.\n

    I disputed your claims that the `egrep` command has *just* been a distro hack all these years, when in fact GNU to this day still distributes `egrep` through its source tarballs and only very recently started to warn about it through the wrapper script.

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n
      Edit: fixed title so it didn’t say “regex expressions”

              It is a great book, although a bit outdated. In particular, nowadays `egrep` is not recommended to use. `grep -E` is a more portable synonim.\n
              \n
              Some notes on you script:\n
              \n
              1. You don’t need to escape slashes in grep regex. In the sed `s///` command better use another character like `s###` so you also can leave slashes unescaped.\n
              2. You usually don’t need to pipe `grep` and `sed`, `sed -n` with regex address and explicit printing command gives the same result as `grep`.\n
              3. You could omit leading slash in your `egrep` regex, so you won’t need to remove it later.\n
              \n
              So I would do the same with\n

            Not directed at you personally, but this is the kind of pointless pedantry from upstream developers that grinds my gears.\n
            \n
            Like, I’ve used `egrep` for 25 years. I don’t know of a still relevant Unix variant in existence that doesn’t have the `egrep` command. But suddenly now, when any other Unix variant but Linux is all but extinct, and all your shell scripts are probably full of bashisms and Linuxisms anyway, *now* there is somehow a portability problem, and they deem it necessary to print out a warning whenever I dare to run `egrep` instead of `grep -E`? C’mon now … If anything, they have just made it *less* portable by spitting out spurious warnings where there weren’t any before.

        > GNU grep, the most widespread implementation, does not include egrep, fgrep and rgrep for years. Distributions (not all, but many) provide shell scripts that simply run grep with corresponding option for backward compatibility. You can learn this from official documentation.\n
        \n
        It seems you need to read the official documentation yourself. While it’s new information to me that `egrep` is no longer a symlink, as it used to be a couple of years ago, but a shell script wrapper to `grep -E` instead, the egrep command is to this day still provided by upstream GNU grep and is installed by default if you run `./configure; make; make install` from source. So it is not a backward compatibility hack provided by the distribution.\n
        \n
        You can check for yourself. Download the source from [ftp.gnu.org/gnu/grep/grep-3.11.tar.gz](https://ftp.gnu.org/gnu/grep/grep-3.11.tar.gz), unpack and look for `src/egrep.sh` or line 1756 of `src/Makefile`. Apparently the change from symlink to shell script was done in 2014, and the deprecation warning was added only last year.\n
        \n
        In any case, my larger point is that the depreciation of `egrep` was a pointless and arbitrary decision that does not benefit users, especially not veterans like myself who have become accustomed to its presence. I don’t mind change, but let’s be honest, most people are not in the habit of checking the minutiae of every little command line utility they use, so a change like this violates the principle of least surprise. It’s one thing if things are changed with a good reason and the users do not only suffer the inconvenience of the change but get to reap the benefits of it as well, but so far I haven’t found any justification for it yet, nor can I think of any.\n
        \n
        So if there is a portability problem with using `egrep` now, it’s a *self-inflicted* portability problem that they caused by deprecating `egrep` in the first place.\n
        \n
        > Also, my scripts are not full of bashisms, gnuisms, linuxisms and other -isms, I try to keep them portable unless it is really necessary to use some unportable command or syntax.\n
        \n
        Good for you. Do you want a cookie or something?

    You are strawmanning, and your links are not countering any point I made. I never disputed the depreciation as fact, and I never recommended that beginners should use `egrep` over `grep -E`\n
    \n
    I disputed your claims that the `egrep` command has *just* been a distro hack all these years, when in fact GNU to this day still distributes `egrep` through its source tarballs and only very recently started to warn about it through the wrapper script. And again, the only “portability problem” here is the fact that they deprecated it in the first place, i.e. a self-inflicted one.\n
    \n
    Then as a Linux and Unix veteran I gave my subjective opinion by lamenting and criticizing the fact that this depreciation happened, and how changes like this always feel like unnecessary pedantry to me. Yes it’s an expression of frustration, but I am allowed to feel frustrated about it. I don’t need people like you invalidating how I feel about breaking changes in software that I use daily.

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n

    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

              It is a great book, although a bit outdated. In particular, nowadays `egrep` is not recommended to use. `grep -E` is a more portable synonim.\n
              \n
              Some notes on you script:\n
              \n
              1. You don’t need to escape slashes in grep regex. In the sed `s///` command better use another character like `s###` so you also can leave slashes unescaped.\n
              2. You usually don’t need to pipe `grep` and `sed`, `sed -n` with regex address and explicit printing command gives the same result as `grep`.\n
              3. You could omit leading slash in your `egrep` regex, so you won’t need to remove it later.\n
              \n

            Not directed at you personally, but this is the kind of pointless pedantry from upstream developers that grinds my gears.\n
            \n
            Like, I’ve used `egrep` for 25 years. I don’t know of a still relevant Unix variant in existence that doesn’t have the `egrep` command. But suddenly now, when any other Unix variant but Linux is all but extinct, and all your shell scripts are probably full of bashisms and Linuxisms anyway, *now* there is somehow a portability problem, and they deem it necessary to print out a warning whenever I dare to run `egrep` instead of `grep -E`? C’mon now … If anything, they have just made it *less* portable by spitting out spurious warnings where there weren’t any before.

        > GNU grep, the most widespread implementation, does not include egrep, fgrep and rgrep for years. Distributions (not all, but many) provide shell scripts that simply run grep with corresponding option for backward compatibility. You can learn this from official documentation.\n
        \n
        It seems you need to read the official documentation yourself. While it’s new information to me that `egrep` is no longer a symlink, as it used to be a couple of years ago, but a shell script wrapper to `grep -E` instead, the egrep command is to this day still provided by upstream GNU grep and is installed by default if you run `./configure; make; make install` from source. So it is not a backward compatibility hack provided by the distribution.\n
        \n
        You can check for yourself. Download the source from [ftp.gnu.org/gnu/grep/grep-3.11.tar.gz](https://ftp.gnu.org/gnu/grep/grep-3.11.tar.gz), unpack and look for `src/egrep.sh` or line 1756 of `src/Makefile`. Apparently the change from symlink to shell script was done in 2014, and the deprecation warning was added only last year.\n
        \n
        In any case, my larger point is that the depreciation of `egrep` was a pointless and arbitrary decision that does not benefit users, especially not veterans like myself who have become accustomed to its presence. I don’t mind change, but let’s be honest, most people are not in the habit of checking the minutiae of every little command line utility they use, so a change like this violates the principle of least surprise. It’s one thing if things are changed with a good reason and the users do not only suffer the inconvenience of the change but get to reap the benefits of it as well, but so far I haven’t found any justification for it yet, nor can I think of any.\n
        \n
        So if there is a portability problem with using `egrep` now, it’s a *self-inflicted* portability problem that they caused by deprecating `egrep` in the first place.\n
        \n
        > Also, my scripts are not full of bashisms, gnuisms, linuxisms and other -isms, I try to keep them portable unless it is really necessary to use some unportable command or syntax.\n
        \n
        Good for you. Do you want a cookie or something?

    You are strawmanning, and your links are not countering any point I made. I never disputed the depreciation as fact, and I never recommended that beginners should use `egrep` over `grep -E`\n
    \n
    I disputed your claims that the `egrep` command has *just* been a distro hack all these years, when in fact GNU to this day still distributes `egrep` through its source tarballs and only very recently started to warn about it through the wrapper script. And again, the only “portability problem” here is the fact that they deprecated it in the first place, i.e. a self-inflicted one.\n
    \n
    Then as a Linux and Unix veteran I gave my subjective opinion by lamenting and criticizing the fact that this depreciation happened, and how changes like this always feel like unnecessary pedantry to me. Yes it’s an expression of frustration, but I am allowed to feel frustrated about it. I don’t need people like you invalidating how I feel about breaking changes in software that I use daily.

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

            It is a great book, although a bit outdated. In particular, nowadays `egrep` is not recommended to use. `grep -E` is a more portable synonim.\n
            \n
            Some notes on you script:\n
            \n
            1. You don’t need to escape slashes in grep regex. In the sed `s///` command better use another character like `s###` so you also can leave slashes unescaped.\n
            2. You usually don’t need to pipe `grep` and `sed`, `sed -n` with regex address and explicit printing command gives the same result as `grep`.\n
            3. You could omit leading slash in your `egrep` regex, so you won’t need to remove it later.\n
            \n

          Not directed at you personally, but this is the kind of pointless pedantry from upstream developers that grinds my gears.\n
          \n
          Like, I’ve used `egrep` for 25 years. I don’t know of a still relevant Unix variant in existence that doesn’t have the `egrep` command. But suddenly now, when any other Unix variant but Linux is all but extinct, and all your shell scripts are probably full of bashisms and Linuxisms anyway, *now* there is somehow a portability problem, and they deem it necessary to print out a warning whenever I dare to run `egrep` instead of `grep -E`? C’mon now … If anything, they have just made it *less* portable by spitting out spurious warnings where there weren’t any before.

      > GNU grep, the most widespread implementation, does not include egrep, fgrep and rgrep for years. Distributions (not all, but many) provide shell scripts that simply run grep with corresponding option for backward compatibility. You can learn this from official documentation.\n
      \n
      It seems you need to read the official documentation yourself. While it’s new information to me that `egrep` is no longer a symlink, as it used to be a couple of years ago, but a shell script wrapper to `grep -E` instead, the egrep command is to this day still provided by upstream GNU grep and is installed by default if you run `./configure; make; make install` from source. So it is not a backward compatibility hack provided by the distribution.\n
      \n
      You can check for yourself. Download the source from [ftp.gnu.org/gnu/grep/grep-3.11.tar.gz](https://ftp.gnu.org/gnu/grep/grep-3.11.tar.gz), unpack and look for `src/egrep.sh` or line 1756 of `src/Makefile`. Apparently the change from symlink to shell script was done in 2014, and the deprecation warning was added only last year.\n
      \n
      In any case, my larger point is that the depreciation of `egrep` was a pointless and arbitrary decision that does not benefit users, especially not veterans like myself who have become accustomed to its presence. I don’t mind change, but let’s be honest, most people are not in the habit of checking the minutiae of every little command line utility they use, so a change like this violates the principle of least surprise. It’s one thing if things are changed with a good reason and the users do not only suffer the inconvenience of the change but get to reap the benefits of it as well, but so far I haven’t found any justification for it yet, nor can I think of any.\n
      \n
      So if there is a portability problem with using `egrep` now, it’s a *self-inflicted* portability problem that they caused by deprecating `egrep` in the first place.\n
      \n
      > Also, my scripts are not full of bashisms, gnuisms, linuxisms and other -isms, I try to keep them portable unless it is really necessary to use some unportable command or syntax.\n
      \n

        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

            It is a great book, although a bit outdated. In particular, nowadays `egrep` is not recommended to use. `grep -E` is a more portable synonim.\n
            \n
            Some notes on you script:\n
            \n
            1. You don’t need to escape slashes in grep regex. In the sed `s///` command better use another character like `s###` so you also can leave slashes unescaped.\n
            2. You usually don’t need to pipe `grep` and `sed`, `sed -n` with regex address and explicit printing command gives the same result as `grep`.\n
            3. You could omit leading slash in your `egrep` regex, so you won’t need to remove it later.\n
            \n
            So I would do the same with\n
            \n

          Not directed at you personally, but this is the kind of pointless pedantry from upstream developers that grinds my gears.\n
          \n
          Like, I’ve used `egrep` for 25 years. I don’t know of a still relevant Unix variant in existence that doesn’t have the `egrep` command. But suddenly now, when any other Unix variant but Linux is all but extinct, and all your shell scripts are probably full of bashisms and Linuxisms anyway, *now* there is somehow a portability problem, and they deem it necessary to print out a warning whenever I dare to run `egrep` instead of `grep -E`? C’mon now … If anything, they have just made it *less* portable by spitting out spurious warnings where there weren’t any before.

      > GNU grep, the most widespread implementation, does not include egrep, fgrep and rgrep for years. Distributions (not all, but many) provide shell scripts that simply run grep with corresponding option for backward compatibility. You can learn this from official documentation.\n
      \n
      It seems you need to read the official documentation yourself. While it’s new information to me that `egrep` is no longer a symlink, as it used to be a couple of years ago, but a shell script wrapper to `grep -E` instead, the egrep command is to this day still provided by upstream GNU grep and is installed by default if you run `./configure; make; make install` from source. So it is not a backward compatibility hack provided by the distribution.\n
      \n
      You can check for yourself. Download the source from [ftp.gnu.org/gnu/grep/grep-3.11.tar.gz](https://ftp.gnu.org/gnu/grep/grep-3.11.tar.gz), unpack and look for `src/egrep.sh` or line 1756 of `src/Makefile`. Apparently the change from symlink to shell script was done in 2014, and the deprecation warning was added only last year.\n
      \n
      In any case, my larger point is that the depreciation of `egrep` was a pointless and arbitrary decision that does not benefit users, especially not veterans like myself who have become accustomed to its presence. I don’t mind change, but let’s be honest, most people are not in the habit of checking the minutiae of every little command line utility they use, so a change like this violates the principle of least surprise. It’s one thing if things are changed with a good reason and the users do not only suffer the inconvenience of the change but get to reap the benefits of it as well, but so far I haven’t found any justification for it yet, nor can I think of any.\n
      \n
      So if there is a portability problem with using `egrep` now, it’s a *self-inflicted* portability problem that they caused by deprecating `egrep` in the first place.\n
      \n
      > Also, my scripts are not full of bashisms, gnuisms, linuxisms and other -isms, I try to keep them portable unless it is really necessary to use some unportable command or syntax.\n
      \n
      Good for you. Do you want a cookie or something?

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

            It is a great book, although a bit outdated. In particular, nowadays `egrep` is not recommended to use. `grep -E` is a more portable synonim.\n

            Some notes on you script:\n
            \n
            1. You don’t need to escape slashes in grep regex. In the sed `s///` command better use another character like `s###` so you also can leave slashes unescaped.\n
            2. You usually don’t need to pipe `grep` and `sed`, `sed -n` with regex address and explicit printing command gives the same result as `grep`.\n
            3. You could omit leading slash in your `egrep` regex, so you won’t need to remove it later.\n

          Not directed at you personally, but this is the kind of pointless pedantry from upstream developers that grinds my gears.\n
          \n
          Like, I’ve used `egrep` for 25 years. I don’t know of a still relevant Unix variant in existence that doesn’t have the `egrep` command. But suddenly now, when any other Unix variant but Linux is all but extinct, and all your shell scripts are probably full of bashisms and Linuxisms anyway, *now* there is somehow a portability problem, and they deem it necessary to print out a warning whenever I dare to run `egrep` instead of `grep -E`? C’mon now … If anything, they have just made it *less* portable by spitting out spurious warnings where there weren’t any before.

      > GNU grep, the most widespread implementation, does not include egrep, fgrep and rgrep for years. Distributions (not all, but many) provide shell scripts that simply run grep with corresponding option for backward compatibility. You can learn this from official documentation.\n
      \n
      It seems you need to read the official documentation yourself. While it’s new information to me that `egrep` is no longer a symlink, as it used to be a couple of years ago, but a shell script wrapper to `grep -E` instead, the egrep command is to this day still provided by upstream GNU grep and is installed by default if you run `./configure; make; make install` from source. So it is not a backward compatibility hack provided by the distribution.\n
      \n
      You can check for yourself. Download the source from [ftp.gnu.org/gnu/grep/grep-3.11.tar.gz](https://ftp.gnu.org/gnu/grep/grep-3.11.tar.gz), unpack and look for `src/egrep.sh` or line 1756 of `src/Makefile`. Apparently the change from symlink to shell script was done in 2014, and the deprecation warning was added only last year.\n
      \n
      In any case, my larger point is that the depreciation of `egrep` was a pointless and arbitrary decision that does not benefit users, especially not veterans like myself who have become accustomed to its presence. I don’t mind change, but let’s be honest, most people are not in the habit of checking the minutiae of every little command line utility they use, so a change like this violates the principle of least surprise. It’s one thing if things are changed with a good reason and the users do not only suffer the inconvenience of the change but get to reap the benefits of it as well, but so far I haven’t found any justification for it yet, nor can I think of any.\n
      \n
      So if there is a portability problem with using `egrep` now, it’s a *self-inflicted* portability problem that they caused by deprecating `egrep` in the first place.\n
      \n
      > Also, my scripts are not full of bashisms, gnuisms, linuxisms and other -isms, I try to keep them portable unless it is really necessary to use some unportable command or syntax.\n
      \n

        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n

        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

              It is a great book, although a bit outdated. In particular, nowadays `egrep` is not recommended to use. `grep -E` is a more portable synonim.\n
              \n
              Some notes on you script:\n
              \n
              1. You don’t need to escape slashes in grep regex. In the sed `s///` command better use another character like `s###` so you also can leave slashes unescaped.\n
              2. You usually don’t need to pipe `grep` and `sed`, `sed -n` with regex address and explicit printing command gives the same result as `grep`.\n
              3. You could omit leading slash in your `egrep` regex, so you won’t need to remove it later.\n
              \n
              So I would do the same with\n

            Not directed at you personally, but this is the kind of pointless pedantry from upstream developers that grinds my gears.\n
            \n
            Like, I’ve used `egrep` for 25 years. I don’t know of a still relevant Unix variant in existence that doesn’t have the `egrep` command. But suddenly now, when any other Unix variant but Linux is all but extinct, and all your shell scripts are probably full of bashisms and Linuxisms anyway, *now* there is somehow a portability problem, and they deem it necessary to print out a warning whenever I dare to run `egrep` instead of `grep -E`? C’mon now … If anything, they have just made it *less* portable by spitting out spurious warnings where there weren’t any before.

        > GNU grep, the most widespread implementation, does not include egrep, fgrep and rgrep for years. Distributions (not all, but many) provide shell scripts that simply run grep with corresponding option for backward compatibility. You can learn this from official documentation.\n
        \n
        It seems you need to read the official documentation yourself. While it’s new information to me that `egrep` is no longer a symlink, as it used to be a couple of years ago, but a shell script wrapper to `grep -E` instead, the egrep command is to this day still provided by upstream GNU grep and is installed by default if you run `./configure; make; make install` from source. So it is not a backward compatibility hack provided by the distribution.\n
        \n
        You can check for yourself. Download the source from [ftp.gnu.org/gnu/grep/grep-3.11.tar.gz](https://ftp.gnu.org/gnu/grep/grep-3.11.tar.gz), unpack and look for `src/egrep.sh` or line 1756 of `src/Makefile`. Apparently the change from symlink to shell script was done in 2014, and the deprecation warning was added only last year.\n
        \n
        In any case, my larger point is that the depreciation of `egrep` was a pointless and arbitrary decision that does not benefit users, especially not veterans like myself who have become accustomed to its presence. I don’t mind change, but let’s be honest, most people are not in the habit of checking the minutiae of every little command line utility they use, so a change like this violates the principle of least surprise. It’s one thing if things are changed with a good reason and the users do not only suffer the inconvenience of the change but get to reap the benefits of it as well, but so far I haven’t found any justification for it yet, nor can I think of any.\n
        \n
        So if there is a portability problem with using `egrep` now, it’s a *self-inflicted* portability problem that they caused by deprecating `egrep` in the first place.\n
        \n
        > Also, my scripts are not full of bashisms, gnuisms, linuxisms and other -isms, I try to keep them portable unless it is really necessary to use some unportable command or syntax.\n
        \n
        Good for you. Do you want a cookie or something?

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

              It is a great book, although a bit outdated. In particular, nowadays `egrep` is not recommended to use. `grep -E` is a more portable synonim.\n
              \n
              Some notes on you script:\n
              \n
              1. You don’t need to escape slashes in grep regex. In the sed `s///` command better use another character like `s###` so you also can leave slashes unescaped.\n
              2. You usually don’t need to pipe `grep` and `sed`, `sed -n` with regex address and explicit printing command gives the same result as `grep`.\n
              3. You could omit leading slash in your `egrep` regex, so you won’t need to remove it later.\n
              \n

            Not directed at you personally, but this is the kind of pointless pedantry from upstream developers that grinds my gears.\n
            \n
            Like, I’ve used `egrep` for 25 years. I don’t know of a still relevant Unix variant in existence that doesn’t have the `egrep` command. But suddenly now, when any other Unix variant but Linux is all but extinct, and all your shell scripts are probably full of bashisms and Linuxisms anyway, *now* there is somehow a portability problem, and they deem it necessary to print out a warning whenever I dare to run `egrep` instead of `grep -E`? C’mon now … If anything, they have just made it *less* portable by spitting out spurious warnings where there weren’t any before.

        > GNU grep, the most widespread implementation, does not include egrep, fgrep and rgrep for years. Distributions (not all, but many) provide shell scripts that simply run grep with corresponding option for backward compatibility. You can learn this from official documentation.\n
        \n
        It seems you need to read the official documentation yourself. While it’s new information to me that `egrep` is no longer a symlink, as it used to be a couple of years ago, but a shell script wrapper to `grep -E` instead, the egrep command is to this day still provided by upstream GNU grep and is installed by default if you run `./configure; make; make install` from source. So it is not a backward compatibility hack provided by the distribution.\n
        \n
        You can check for yourself. Download the source from [ftp.gnu.org/gnu/grep/grep-3.11.tar.gz](https://ftp.gnu.org/gnu/grep/grep-3.11.tar.gz), unpack and look for `src/egrep.sh` or line 1756 of `src/Makefile`. Apparently the change from symlink to shell script was done in 2014, and the deprecation warning was added only last year.\n
        \n
        In any case, my larger point is that the depreciation of `egrep` was a pointless and arbitrary decision that does not benefit users, especially not veterans like myself who have become accustomed to its presence. I don’t mind change, but let’s be honest, most people are not in the habit of checking the minutiae of every little command line utility they use, so a change like this violates the principle of least surprise. It’s one thing if things are changed with a good reason and the users do not only suffer the inconvenience of the change but get to reap the benefits of it as well, but so far I haven’t found any justification for it yet, nor can I think of any.\n
        \n
        So if there is a portability problem with using `egrep` now, it’s a *self-inflicted* portability problem that they caused by deprecating `egrep` in the first place.\n
        \n
        > Also, my scripts are not full of bashisms, gnuisms, linuxisms and other -isms, I try to keep them portable unless it is really necessary to use some unportable command or syntax.\n
        \n
        Good for you. Do you want a cookie or something?

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +slug: "My-First-Regular-Expressions"
    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

              It is a great book, although a bit outdated. In particular, nowadays `egrep` is not recommended to use. `grep -E` is a more portable synonim.\n
              \n
              Some notes on you script:\n
              \n
              1. You don’t need to escape slashes in grep regex. In the sed `s///` command better use another character like `s###` so you also can leave slashes unescaped.\n
              2. You usually don’t need to pipe `grep` and `sed`, `sed -n` with regex address and explicit printing command gives the same result as `grep`.\n

            Like, I’ve used `egrep` for 25 years. I don’t know of a still relevant Unix variant in existence that doesn’t have the `egrep` command. But suddenly now, when any other Unix variant but Linux is all but extinct, and all your shell scripts are probably full of bashisms and Linuxisms anyway, *now* there is somehow a portability problem, and they deem it necessary to print out a warning whenever I dare to run `egrep` instead of `grep -E`? C’mon now … If anything, they have just made it *less* portable by spitting out spurious warnings where there weren’t any before.

        > GNU grep, the most widespread implementation, does not include egrep, fgrep and rgrep for years. Distributions (not all, but many) provide shell scripts that simply run grep with corresponding option for backward compatibility. You can learn this from official documentation.\n
        \n
        It seems you need to read the official documentation yourself. While it’s new information to me that `egrep` is no longer a symlink, as it used to be a couple of years ago, but a shell script wrapper to `grep -E` instead, the egrep command is to this day still provided by upstream GNU grep and is installed by default if you run `./configure; make; make install` from source. So it is not a backward compatibility hack provided by the distribution.\n
        \n
        You can check for yourself. Download the source from [ftp.gnu.org/gnu/grep/grep-3.11.tar.gz](https://ftp.gnu.org/gnu/grep/grep-3.11.tar.gz), unpack and look for `src/egrep.sh` or line 1756 of `src/Makefile`. Apparently the change from symlink to shell script was done in 2014, and the deprecation warning was added only last year.\n
        \n
        In any case, my larger point is that the depreciation of `egrep` was a pointless and arbitrary decision that does not benefit users, especially not veterans like myself who have become accustomed to its presence. I don’t mind change, but let’s be honest, most people are not in the habit of checking the minutiae of every little command line utility they use, so a change like this violates the principle of least surprise. It’s one thing if things are changed with a good reason and the users do not only suffer the inconvenience of the change but get to reap the benefits of it as well, but so far I haven’t found any justification for it yet, nor can I think of any.\n
        \n
        So if there is a portability problem with using `egrep` now, it’s a *self-inflicted* portability problem that they caused by deprecating `egrep` in the first place.\n
        \n
        > Also, my scripts are not full of bashisms, gnuisms, linuxisms and other -isms, I try to keep them portable unless it is really necessary to use some unportable command or syntax.\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n
        \n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +slug: "My-First-Regular-Expressions"
    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

    +slug: "My-First-Regular-Expressions"
    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +slug: "My-First-Regular-Expressions"
    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +slug: "My-First-Regular-Expressions"
    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +slug: "My-First-Regular-Expressions"
    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n
        \n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +slug: "My-First-Regular-Expressions"
    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n

    +slug: "My-First-Regular-Expressions"
    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

    +slug: "My-First-Regular-Expressions"
    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n

    +slug: "My-First-Regular-Expressions"
    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n
        \n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +slug: "My-First-Regular-Expressions"
    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

    I can also recommend the book the TS mentioned, it is very good and after reading it you will understand regular expressions. It’s fine to use a cheat sheet if you want, cause if you don’t do it regularly the knowledge can sag, but the understanding is what matters. Also depending on the context, different implementations can have slightly different syntax or modifiers to be aware of.\n
    \n
    I lent out the book to my brother once and he somehow lost it, so I never got it back. Don’t lend out book guys.\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +slug: "My-First-Regular-Expressions"
    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

    +slug: "My-First-Regular-Expressions"
    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +slug: "My-First-Regular-Expressions"
    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +slug: "My-First-Regular-Expressions"
    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n
        \n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +slug: "My-First-Regular-Expressions"
    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n

      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n
        \n

    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n

      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n

      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +slug: "My-First-Regular-Expressions"
    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +slug: "My-First-Regular-Expressions"
    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +slug: "My-First-Regular-Expressions"
    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

      +description: """
        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +slug: "My-First-Regular-Expressions"
    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

    +slug: "My-First-Regular-Expressions"
    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +slug: "My-First-Regular-Expressions"
    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

    +slug: "My-First-Regular-Expressions"
    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +slug: "My-First-Regular-Expressions"
    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n

        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

    +title: "My First Regular Expressions"
    +url: null
    +body: """
      I’ve been reading *Mastering Regular Expressions* by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with.\n
      \n
      What’s I’m so happy about is that I wrote these expressions. I understand exactly what they do and the purpose of each character in each expression.\n
      \n
      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n

        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n

      I’ve used regex in the past. Stuff cobbled together from stack overflow, but I never really understood how they worked or what the expressions meant, just that they did what I needed them to do at the time.\n
      \n
      I’m only about 10% of the way through the book, but already I understand so much more than I ever did about regex *(I also recognize I have a lot to learn)*.\n
      \n
      I wrote the expressions to be used with egrep and sed to generate and clean up a list of filenames pulled out of tarballs. *(movies I’ve ripped from my DVD collection and tarballed to archive them)*.\n
      \n
      The first expression I wrote was this one used with tar and egrep to list the files in the tarball and get just the name of the video file:\n
      \n
      `tar -tzvf file.tar.gz | egrep -o ‘/[^/]*.m(kv|p4)’ > movielist`\n
      \n
      Which gives me a list of movies of which this is an example:\n
      \n
      `/The.Hunger.Games.(2012).[tmdbid-70160].mp4`\n
      \n
      Then I used sed with the expression groups to remove:\n
      \n
      - the leading forward slash\n
      - Everything from `.[` to the end\n
      - All of the periods in between words\n
      \n
      And the last expression checks for one or more spaces and replaces them with a single space.\n
      \n
      This is the full sed command:\n
      \n
      `sed -Eie ‘s/^///; s/.[[a-z]±[0-9]+].m(p4|kv)//; s/[^a-zA-Z0-9()&amp;-]/ /g; s/ +/ /g’ movielist`\n
      \n
      Which leaves me with a pretty list of movies that looks like this:\n
      \n
      `The Hunger Games (2012)`\n
      \n
      I’m sure this could be done more elegantly, and I’m happy for any feedback on how to do that! For now, I’m just excited that I’m beginning to understand regex and how to use it!\n
      \n

  +description: """
    From Wikipedia, the free encyclopedia\n
    \n
    Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
    \n
    Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
    \n
    ### Rules\n
    \n
    - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
    - No misinformation\n
    - No NSFW content\n
    - No hate speech, bigotry, etc\n
    \n
