      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

    `ash` (and its successor `dash` found on other distros) is a POSIX-y shell rather than a `sh` clone, so it has all(? most?) of the POSIX feature set, whose syntax may indeed have been 'borrowed' from shells that came later than `sh`.\n
    \n
    Not sure if there's a "parent" from which both `ash` and `bash` inherit the syntax or whether `bash` is the true source, but that doesn't really matter here.\n
    \n
    All that said, it's worth checking to see if your system has a command on the PATH called `[[`. That has been one way that `[[` support can be added to a system when the shell itself might not support it. Note that command names don't have to be alphanumeric like functions tend to be in a programming language (or *other* languages if you consider that the shell can be used for programming too), so `[[` is perfectly valid!

      [For reference, I’m talking about Ash in Alpine Linux here, which is part of BusyBox.]\n
      \n
      I thought I knew the big differences, but it turns out I’ve had false assumptions for years. Ash *does* support `[[ double square brackets ]]` and (as best I can tell) all of Bash’s logical trickery inside them. It also supports ${VARIABLE_SUBSTRINGS:5:12}` which was another surprise.\n
      \n
      At this stage, the only things I’ve found that Bash can do that Ash can’t are:\n
      \n
      - Arrays, which Bash doesn’t seem to do well anyway\n
      - Brace expansion, which is awesome but I can live without it.\n
      \n
      What else is there? Did Ash used to be more limited? The double square bracket thing really surprised me.

        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

  +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
