      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 want to run a command and see all of its output on the left hand side, while simultaneously searching/grepping for particular lines on the right hand side. In other words, I want a temporary vertically split screen in my CLI, ideally with scrollback on each side of the split, but where I expect the left hand side to be scrolling thousands of lines quickly, while on the right hand side is a slow accumulation of “matches” to my grep.\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

      I want to run a command and see all of its output on the left hand side, while simultaneously searching/grepping for particular lines on the right hand side. In other words, I want a temporary vertically split screen in my CLI, ideally with scrollback on each side of the split, but where I expect the left hand side to be scrolling thousands of lines quickly, while on the right hand side is a slow accumulation of “matches” to my grep.\n

      In case this is an X/Y problem: The specific command I’m trying to run is an rsync simulation (dry-run) where I want to both check that the command works, and subsequently check that there are no `denied` errors.

    +url: null
    +body: """
      I want to run a command and see all of its output on the left hand side, while simultaneously searching/grepping for particular lines on the right hand side. In other words, I want a temporary vertically split screen in my CLI, ideally with scrollback on each side of the split, but where I expect the left hand side to be scrolling thousands of lines quickly, while on the right hand side is a slow accumulation of “matches” to my grep.\n
      \n
      Is this possible today? What tools would you recommend to accomplish this?\n
      \n
      EDIT: To be clear, a one-liner is preferable over learning tmux or screen, although this does motivate me to perhaps begin learning tmux.\n
      \n
      In case this is an X/Y problem: The specific command I’m trying to run is an rsync simulation (dry-run) where I want to both check that the command works, and subsequently check that there are no `denied` errors. The recommended way to do this is to run the command twice, as follows (but I want to combine it into one pass):\n
      \n
      ```\n
      \n
      <span style="color:#323232;"># first specify the "-n" parameter so rsync will simulate its operation. You should use this before you start:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/\n
      </span><span style="color:#323232;">\n
      </span><span style="color:#323232;"># check for permission denied errors in your homedir:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/ | grep denied\n

      I want to run a command and see all of its output on the left hand side, while simultaneously searching/grepping for particular lines on the right hand side.

        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

        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

    +url: null
    +body: """
      I want to run a command and see all of its output on the left hand side, while simultaneously searching/grepping for particular lines on the right hand side. In other words, I want a temporary vertically split screen in my CLI, ideally with scrollback on each side of the split, but where I expect the left hand side to be scrolling thousands of lines quickly, while on the right hand side is a slow accumulation of “matches” to my grep.\n
      \n
      Is this possible today? What tools would you recommend to accomplish this?\n
      \n
      EDIT: To be clear, a one-liner is preferable over learning tmux or screen, although this does motivate me to perhaps begin learning tmux.\n
      \n
      In case this is an X/Y problem: The specific command I’m trying to run is an rsync simulation (dry-run) where I want to both check that the command works, and subsequently check that there are no `denied` errors. The recommended way to do this is to run the command twice, as follows (but I want to combine it into one pass):\n
      \n
      ```\n
      \n
      <span style="color:#323232;"># first specify the "-n" parameter so rsync will simulate its operation. You should use this before you start:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/\n
      </span><span style="color:#323232;">\n
      </span><span style="color:#323232;"># check for permission denied errors in your homedir:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/ | grep denied\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

    +body: """
      I want to run a command and see all of its output on the left hand side, while simultaneously searching/grepping for particular lines on the right hand side. In other words, I want a temporary vertically split screen in my CLI, ideally with scrollback on each side of the split, but where I expect the left hand side to be scrolling thousands of lines quickly, while on the right hand side is a slow accumulation of “matches” to my grep.\n
      \n
      Is this possible today? What tools would you recommend to accomplish this?\n
      \n
      EDIT: To be clear, a one-liner is preferable over learning tmux or screen, although this does motivate me to perhaps begin learning tmux.\n
      \n
      In case this is an X/Y problem: The specific command I’m trying to run is an rsync simulation (dry-run) where I want to both check that the command works, and subsequently check that there are no `denied` errors. The recommended way to do this is to run the command twice, as follows (but I want to combine it into one pass):\n
      \n
      ```\n
      \n
      <span style="color:#323232;"># first specify the "-n" parameter so rsync will simulate its operation. You should use this before you start:\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

    +url: null
    +body: """
      I want to run a command and see all of its output on the left hand side, while simultaneously searching/grepping for particular lines on the right hand side. In other words, I want a temporary vertically split screen in my CLI, ideally with scrollback on each side of the split, but where I expect the left hand side to be scrolling thousands of lines quickly, while on the right hand side is a slow accumulation of “matches” to my grep.\n
      \n
      Is this possible today? What tools would you recommend to accomplish this?\n
      \n
      EDIT: To be clear, a one-liner is preferable over learning tmux or screen, although this does motivate me to perhaps begin learning tmux.\n
      \n
      In case this is an X/Y problem: The specific command I’m trying to run is an rsync simulation (dry-run) where I want to both check that the command works, and subsequently check that there are no `denied` errors. The recommended way to do this is to run the command twice, as follows (but I want to combine it into one pass):\n
      \n
      ```\n
      \n
      <span style="color:#323232;"># first specify the "-n" parameter so rsync will simulate its operation. You should use this before you start:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/\n
      </span><span style="color:#323232;">\n
      </span><span style="color:#323232;"># check for permission denied errors in your homedir:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/ | grep denied\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

        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

    +url: null
    +body: """
      I want to run a command and see all of its output on the left hand side, while simultaneously searching/grepping for particular lines on the right hand side. In other words, I want a temporary vertically split screen in my CLI, ideally with scrollback on each side of the split, but where I expect the left hand side to be scrolling thousands of lines quickly, while on the right hand side is a slow accumulation of “matches” to my grep.\n
      \n
      Is this possible today? What tools would you recommend to accomplish this?\n
      \n
      EDIT: To be clear, a one-liner is preferable over learning tmux or screen, although this does motivate me to perhaps begin learning tmux.\n
      \n
      In case this is an X/Y problem: The specific command I’m trying to run is an rsync simulation (dry-run) where I want to both check that the command works, and subsequently check that there are no `denied` errors. The recommended way to do this is to run the command twice, as follows (but I want to combine it into one pass):\n
      \n
      ```\n
      \n
      <span style="color:#323232;"># first specify the "-n" parameter so rsync will simulate its operation. You should use this before you start:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/\n
      </span><span style="color:#323232;">\n
      </span><span style="color:#323232;"># check for permission denied errors in your homedir:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/ | grep denied\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

    +url: null
    +body: """
      I want to run a command and see all of its output on the left hand side, while simultaneously searching/grepping for particular lines on the right hand side. In other words, I want a temporary vertically split screen in my CLI, ideally with scrollback on each side of the split, but where I expect the left hand side to be scrolling thousands of lines quickly, while on the right hand side is a slow accumulation of “matches” to my grep.\n
      \n
      Is this possible today? What tools would you recommend to accomplish this?\n
      \n
      EDIT: To be clear, a one-liner is preferable over learning tmux or screen, although this does motivate me to perhaps begin learning tmux.\n
      \n
      In case this is an X/Y problem: The specific command I’m trying to run is an rsync simulation (dry-run) where I want to both check that the command works, and subsequently check that there are no `denied` errors. The recommended way to do this is to run the command twice, as follows (but I want to combine it into one pass):\n
      \n
      ```\n
      \n
      <span style="color:#323232;"># first specify the "-n" parameter so rsync will simulate its operation. You should use this before you start:\n

    +url: null
    +body: """
      I want to run a command and see all of its output on the left hand side, while simultaneously searching/grepping for particular lines on the right hand side. In other words, I want a temporary vertically split screen in my CLI, ideally with scrollback on each side of the split, but where I expect the left hand side to be scrolling thousands of lines quickly, while on the right hand side is a slow accumulation of “matches” to my grep.\n
      \n
      Is this possible today? What tools would you recommend to accomplish this?\n
      \n
      EDIT: To be clear, a one-liner is preferable over learning tmux or screen, although this does motivate me to perhaps begin learning tmux.\n
      \n
      In case this is an X/Y problem: The specific command I’m trying to run is an rsync simulation (dry-run) where I want to both check that the command works, and subsequently check that there are no `denied` errors. The recommended way to do this is to run the command twice, as follows (but I want to combine it into one pass):\n
      \n
      ```\n
      \n
      <span style="color:#323232;"># first specify the "-n" parameter so rsync will simulate its operation. You should use this before you start:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/\n
      </span><span style="color:#323232;">\n
      </span><span style="color:#323232;"># check for permission denied errors in your homedir:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/ | grep denied\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

    +title: "Is there such a thing as split-screen grep?"
    +url: null
    +body: """
      I want to run a command and see all of its output on the left hand side, while simultaneously searching/grepping for particular lines on the right hand side. In other words, I want a temporary vertically split screen in my CLI, ideally with scrollback on each side of the split, but where I expect the left hand side to be scrolling thousands of lines quickly, while on the right hand side is a slow accumulation of “matches” to my grep.\n
      \n
      Is this possible today? What tools would you recommend to accomplish this?\n
      \n
      EDIT: To be clear, a one-liner is preferable over learning tmux or screen, although this does motivate me to perhaps begin learning tmux.\n
      \n
      In case this is an X/Y problem: The specific command I’m trying to run is an rsync simulation (dry-run) where I want to both check that the command works, and subsequently check that there are no `denied` errors. The recommended way to do this is to run the command twice, as follows (but I want to combine it into one pass):\n
      \n
      ```\n
      \n
      <span style="color:#323232;"># first specify the "-n" parameter so rsync will simulate its operation. You should use this before you start:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/\n
      </span><span style="color:#323232;">\n
      </span><span style="color:#323232;"># check for permission denied errors in your homedir:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/ | grep denied\n
      </span>\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

    +url: null
    +body: """
      I want to run a command and see all of its output on the left hand side, while simultaneously searching/grepping for particular lines on the right hand side. In other words, I want a temporary vertically split screen in my CLI, ideally with scrollback on each side of the split, but where I expect the left hand side to be scrolling thousands of lines quickly, while on the right hand side is a slow accumulation of “matches” to my grep.\n
      \n
      Is this possible today? What tools would you recommend to accomplish this?\n
      \n
      EDIT: To be clear, a one-liner is preferable over learning tmux or screen, although this does motivate me to perhaps begin learning tmux.\n
      \n
      In case this is an X/Y problem: The specific command I’m trying to run is an rsync simulation (dry-run) where I want to both check that the command works, and subsequently check that there are no `denied` errors. The recommended way to do this is to run the command twice, as follows (but I want to combine it into one pass):\n
      \n
      ```\n
      \n
      <span style="color:#323232;"># first specify the "-n" parameter so rsync will simulate its operation. You should use this before you start:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/\n
      </span><span style="color:#323232;">\n
      </span><span style="color:#323232;"># check for permission denied errors in your homedir:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/ | grep denied\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: "Is there such a thing as split-screen grep?"
    +url: null
    +body: """
      I want to run a command and see all of its output on the left hand side, while simultaneously searching/grepping for particular lines on the right hand side. In other words, I want a temporary vertically split screen in my CLI, ideally with scrollback on each side of the split, but where I expect the left hand side to be scrolling thousands of lines quickly, while on the right hand side is a slow accumulation of “matches” to my grep.\n
      \n
      Is this possible today? What tools would you recommend to accomplish this?\n
      \n
      EDIT: To be clear, a one-liner is preferable over learning tmux or screen, although this does motivate me to perhaps begin learning tmux.\n
      \n
      In case this is an X/Y problem: The specific command I’m trying to run is an rsync simulation (dry-run) where I want to both check that the command works, and subsequently check that there are no `denied` errors. The recommended way to do this is to run the command twice, as follows (but I want to combine it into one pass):\n
      \n
      ```\n
      \n
      <span style="color:#323232;"># first specify the "-n" parameter so rsync will simulate its operation. You should use this before you start:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/\n
      </span><span style="color:#323232;">\n
      </span><span style="color:#323232;"># check for permission denied errors in your homedir:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/ | grep denied\n
      </span>\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

    +url: null
    +body: """
      I want to run a command and see all of its output on the left hand side, while simultaneously searching/grepping for particular lines on the right hand side. In other words, I want a temporary vertically split screen in my CLI, ideally with scrollback on each side of the split, but where I expect the left hand side to be scrolling thousands of lines quickly, while on the right hand side is a slow accumulation of “matches” to my grep.\n
      \n
      Is this possible today? What tools would you recommend to accomplish this?\n
      \n
      EDIT: To be clear, a one-liner is preferable over learning tmux or screen, although this does motivate me to perhaps begin learning tmux.\n
      \n
      In case this is an X/Y problem: The specific command I’m trying to run is an rsync simulation (dry-run) where I want to both check that the command works, and subsequently check that there are no `denied` errors. The recommended way to do this is to run the command twice, as follows (but I want to combine it into one pass):\n
      \n
      ```\n
      \n
      <span style="color:#323232;"># first specify the "-n" parameter so rsync will simulate its operation. You should use this before you start:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/\n
      </span><span style="color:#323232;">\n
      </span><span style="color:#323232;"># check for permission denied errors in your homedir:\n

    +url: null
    +body: """
      I want to run a command and see all of its output on the left hand side, while simultaneously searching/grepping for particular lines on the right hand side. In other words, I want a temporary vertically split screen in my CLI, ideally with scrollback on each side of the split, but where I expect the left hand side to be scrolling thousands of lines quickly, while on the right hand side is a slow accumulation of “matches” to my grep.\n
      \n
      Is this possible today? What tools would you recommend to accomplish this?\n
      \n
      EDIT: To be clear, a one-liner is preferable over learning tmux or screen, although this does motivate me to perhaps begin learning tmux.\n
      \n
      In case this is an X/Y problem: The specific command I’m trying to run is an rsync simulation (dry-run) where I want to both check that the command works, and subsequently check that there are no `denied` errors. The recommended way to do this is to run the command twice, as follows (but I want to combine it into one pass):\n
      \n
      ```\n
      \n
      <span style="color:#323232;"># first specify the "-n" parameter so rsync will simulate its operation. You should use this before you start:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/\n
      </span><span style="color:#323232;">\n
      </span><span style="color:#323232;"># check for permission denied errors in your homedir:\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
      EDIT: To be clear, a one-liner is preferable over learning tmux or screen, although this does motivate me to perhaps begin learning tmux.\n
      \n
      In case this is an X/Y problem: The specific command I’m trying to run is an rsync simulation (dry-run) where I want to both check that the command works, and subsequently check that there are no `denied` errors. The recommended way to do this is to run the command twice, as follows (but I want to combine it into one pass):\n
      \n
      ```\n
      \n
      <span style="color:#323232;"># first specify the "-n" parameter so rsync will simulate its operation. You should use this before you start:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/\n
      </span><span style="color:#323232;">\n
      </span><span style="color:#323232;"># check for permission denied errors in your homedir:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/ | grep denied\n
      </span>\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 want to run a command and see all of its output on the left hand side, while simultaneously searching/grepping for particular lines on the right hand side.

        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: "Is there such a thing as split-screen grep?"
    +url: null
    +body: """
      I want to run a command and see all of its output on the left hand side, while simultaneously searching/grepping for particular lines on the right hand side. In other words, I want a temporary vertically split screen in my CLI, ideally with scrollback on each side of the split, but where I expect the left hand side to be scrolling thousands of lines quickly, while on the right hand side is a slow accumulation of “matches” to my grep.\n
      \n
      Is this possible today? What tools would you recommend to accomplish this?\n
      \n
      EDIT: To be clear, a one-liner is preferable over learning tmux or screen, although this does motivate me to perhaps begin learning tmux.\n
      \n
      In case this is an X/Y problem: The specific command I’m trying to run is an rsync simulation (dry-run) where I want to both check that the command works, and subsequently check that there are no `denied` errors. The recommended way to do this is to run the command twice, as follows (but I want to combine it into one pass):\n
      \n
      ```\n
      \n
      <span style="color:#323232;"># first specify the "-n" parameter so rsync will simulate its operation. You should use this before you start:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/\n
      </span><span style="color:#323232;">\n
      </span><span style="color:#323232;"># check for permission denied errors in your homedir:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/ | grep denied\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: "Is there such a thing as split-screen grep?"
    +url: null
    +body: """
      I want to run a command and see all of its output on the left hand side, while simultaneously searching/grepping for particular lines on the right hand side. In other words, I want a temporary vertically split screen in my CLI, ideally with scrollback on each side of the split, but where I expect the left hand side to be scrolling thousands of lines quickly, while on the right hand side is a slow accumulation of “matches” to my grep.\n
      \n
      Is this possible today? What tools would you recommend to accomplish this?\n
      \n
      EDIT: To be clear, a one-liner is preferable over learning tmux or screen, although this does motivate me to perhaps begin learning tmux.\n
      \n
      In case this is an X/Y problem: The specific command I’m trying to run is an rsync simulation (dry-run) where I want to both check that the command works, and subsequently check that there are no `denied` errors. The recommended way to do this is to run the command twice, as follows (but I want to combine it into one pass):\n
      \n
      ```\n
      \n
      <span style="color:#323232;"># first specify the "-n" parameter so rsync will simulate its operation. You should use this before you start:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/\n
      </span><span style="color:#323232;">\n
      </span><span style="color:#323232;"># check for permission denied errors in your homedir:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/ | grep denied\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: "Is there such a thing as split-screen grep?"
    +url: null
    +body: """
      I want to run a command and see all of its output on the left hand side, while simultaneously searching/grepping for particular lines on the right hand side. In other words, I want a temporary vertically split screen in my CLI, ideally with scrollback on each side of the split, but where I expect the left hand side to be scrolling thousands of lines quickly, while on the right hand side is a slow accumulation of “matches” to my grep.\n
      \n
      Is this possible today? What tools would you recommend to accomplish this?\n
      \n
      EDIT: To be clear, a one-liner is preferable over learning tmux or screen, although this does motivate me to perhaps begin learning tmux.\n
      \n
      In case this is an X/Y problem: The specific command I’m trying to run is an rsync simulation (dry-run) where I want to both check that the command works, and subsequently check that there are no `denied` errors. The recommended way to do this is to run the command twice, as follows (but I want to combine it into one pass):\n
      \n
      ```\n
      \n
      <span style="color:#323232;"># first specify the "-n" parameter so rsync will simulate its operation. You should use this before you start:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/\n
      </span><span style="color:#323232;">\n
      </span><span style="color:#323232;"># check for permission denied errors in your homedir:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/ | grep denied\n

    +title: "Is there such a thing as split-screen grep?"
    +url: null
    +body: """
      I want to run a command and see all of its output on the left hand side, while simultaneously searching/grepping for particular lines on the right hand side. In other words, I want a temporary vertically split screen in my CLI, ideally with scrollback on each side of the split, but where I expect the left hand side to be scrolling thousands of lines quickly, while on the right hand side is a slow accumulation of “matches” to my grep.\n
      \n
      Is this possible today? What tools would you recommend to accomplish this?\n
      \n
      EDIT: To be clear, a one-liner is preferable over learning tmux or screen, although this does motivate me to perhaps begin learning tmux.\n
      \n
      In case this is an X/Y problem: The specific command I’m trying to run is an rsync simulation (dry-run) where I want to both check that the command works, and subsequently check that there are no `denied` errors. The recommended way to do this is to run the command twice, as follows (but I want to combine it into one pass):\n
      \n
      ```\n
      \n
      <span style="color:#323232;"># first specify the "-n" parameter so rsync will simulate its operation. You should use this before you start:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/\n
      </span><span style="color:#323232;">\n
      </span><span style="color:#323232;"># check for permission denied errors in your homedir:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/ | grep denied\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: "Is there such a thing as split-screen grep?"
    +url: null
    +body: """
      I want to run a command and see all of its output on the left hand side, while simultaneously searching/grepping for particular lines on the right hand side. In other words, I want a temporary vertically split screen in my CLI, ideally with scrollback on each side of the split, but where I expect the left hand side to be scrolling thousands of lines quickly, while on the right hand side is a slow accumulation of “matches” to my grep.\n
      \n
      Is this possible today? What tools would you recommend to accomplish this?\n
      \n
      EDIT: To be clear, a one-liner is preferable over learning tmux or screen, although this does motivate me to perhaps begin learning tmux.\n
      \n
      In case this is an X/Y problem: The specific command I’m trying to run is an rsync simulation (dry-run) where I want to both check that the command works, and subsequently check that there are no `denied` errors. The recommended way to do this is to run the command twice, as follows (but I want to combine it into one pass):\n
      \n
      ```\n
      \n
      <span style="color:#323232;"># first specify the "-n" parameter so rsync will simulate its operation. You should use this before you start:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/\n
      </span><span style="color:#323232;">\n
      </span><span style="color:#323232;"># check for permission denied errors in your homedir:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/ | grep denied\n
      </span>\n

    +url: null
    +body: """
      I want to run a command and see all of its output on the left hand side, while simultaneously searching/grepping for particular lines on the right hand side. In other words, I want a temporary vertically split screen in my CLI, ideally with scrollback on each side of the split, but where I expect the left hand side to be scrolling thousands of lines quickly, while on the right hand side is a slow accumulation of “matches” to my grep.\n
      \n
      Is this possible today? What tools would you recommend to accomplish this?\n
      \n
      EDIT: To be clear, a one-liner is preferable over learning tmux or screen, although this does motivate me to perhaps begin learning tmux.\n
      \n
      In case this is an X/Y problem: The specific command I’m trying to run is an rsync simulation (dry-run) where I want to both check that the command works, and subsequently check that there are no `denied` errors. The recommended way to do this is to run the command twice, as follows (but I want to combine it into one pass):\n
      \n
      ```\n
      \n
      <span style="color:#323232;"># first specify the "-n" parameter so rsync will simulate its operation. You should use this before you start:\n

      I want to run a command and see all of its output on the left hand side, while simultaneously searching/grepping for particular lines on the right hand side. In other words, I want a temporary vertically split screen in my CLI, ideally with scrollback on each side of the split, but where I expect the left hand side to be scrolling thousands of lines quickly, while on the right hand side is a slow accumulation of “matches” to my grep.\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

      I want to run a command and see all of its output on the left hand side, while simultaneously searching/grepping for particular lines on the right hand side.

    Tmux is a very helpful terminal multiplexer, meaning it can split your terminal into multiple panes. So, create two side by side panes, then one way of doing it is:\n
    \n
    - on the left, run `your cmd | tee >(grep ‘denied’ > error.log)`\n
    - on the right, run `tail -f error.log`\n
    \n
    The `tee` process takes it’s standard in, and writes itbto both standard out, so you see all the lines, and the path it’s been given. The `>(…)` operator runs the grep in a subprocess, and returns the path to it’s standard input pipe, so `grep` receives every line, and writes the denied lines to a log file which you display with `tail` in the other pane.\n
    \n
    Rather than using a file for error.log you could also use a named pipe in much the same way.

        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

    +url: null
    +body: """
      I want to run a command and see all of its output on the left hand side, while simultaneously searching/grepping for particular lines on the right hand side. In other words, I want a temporary vertically split screen in my CLI, ideally with scrollback on each side of the split, but where I expect the left hand side to be scrolling thousands of lines quickly, while on the right hand side is a slow accumulation of “matches” to my grep.\n
      \n
      Is this possible today? What tools would you recommend to accomplish this?\n
      \n
      EDIT: To be clear, a one-liner is preferable over learning tmux or screen, although this does motivate me to perhaps begin learning tmux.\n
      \n
      In case this is an X/Y problem: The specific command I’m trying to run is an rsync simulation (dry-run) where I want to both check that the command works, and subsequently check that there are no `denied` errors. The recommended way to do this is to run the command twice, as follows (but I want to combine it into one pass):\n
      \n
      ```\n
      \n
      <span style="color:#323232;"># first specify the "-n" parameter so rsync will simulate its operation. You should use this before you start:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/\n

    +url: null
    +body: """
      I want to run a command and see all of its output on the left hand side, while simultaneously searching/grepping for particular lines on the right hand side. In other words, I want a temporary vertically split screen in my CLI, ideally with scrollback on each side of the split, but where I expect the left hand side to be scrolling thousands of lines quickly, while on the right hand side is a slow accumulation of “matches” to my grep.\n
      \n
      Is this possible today? What tools would you recommend to accomplish this?\n
      \n
      EDIT: To be clear, a one-liner is preferable over learning tmux or screen, although this does motivate me to perhaps begin learning tmux.\n
      \n
      In case this is an X/Y problem: The specific command I’m trying to run is an rsync simulation (dry-run) where I want to both check that the command works, and subsequently check that there are no `denied` errors. The recommended way to do this is to run the command twice, as follows (but I want to combine it into one pass):\n
      \n
      ```\n
      \n
      <span style="color:#323232;"># first specify the "-n" parameter so rsync will simulate its operation. You should use this before you start:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/\n
      </span><span style="color:#323232;">\n
      </span><span style="color:#323232;"># check for permission denied errors in your homedir:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/ | grep denied\n

      Tmux is a very helpful terminal multiplexer, meaning it can split your terminal into multiple panes. So, create two side by side panes, then one way of doing it is:\n
      \n
      - on the left, run `your cmd | tee >(grep ‘denied’ > error.log)`\n
      - on the right, run `tail -f error.log`\n
      \n
      The `tee` process takes it’s standard in, and writes itbto both standard out, so you see all the lines, and the path it’s been given. The `>(…)` operator runs the grep in a subprocess, and returns the path to it’s standard input pipe, so `grep` receives every line, and writes the denied lines to a log file which you display with `tail` in the other pane.\n
      \n
      Rather than using a file for error.log you could also use a named pipe in much the same way.

        Tmux is a very helpful terminal multiplexer, meaning it can split your terminal into multiple panes. So, create two side by side panes, then one way of doing it is:\n
        \n
        - on the left, run `your cmd | tee >(grep ‘denied’ > error.log)`\n
        - on the right, run `tail -f error.log`\n
        \n
        The `tee` process takes it’s standard in, and writes itbto both standard out, so you see all the lines, and the path it’s been given. The `>(…)` operator runs the grep in a subprocess, and returns the path to it’s standard input pipe, so `grep` receives every line, and writes the denied lines to a log file which you display with `tail` in the other pane.\n
        \n
        Rather than using a file for error.log you could also use a named pipe in much the same way.

    Sorry for th slow answer, I’ve been away. There is a way, if it’s still useful to you:\n
    \n
    First, create a named fifo, you only need to do this once:\n
    \n
    ```\n
    \n
    <span style="color:#323232;">mkfifo logview\n
    </span>\n
    ```\n
    \n
    Run your rsync in one pane, with a filtered view in the second:\n
    \n
    ```\n
    \n
    <span style="color:#323232;">tmux new 'rsync ...options... |& tee logview' ; split-window -h 'grep "denied" logview'\n
    </span>\n
    ```\n
    \n
    Replace `…options…` with your normal rsync command line.\n
    \n
    That should give you a split view, with all the normal messages on the left, and only messages containing ‘denied’ on the right.\n
    \n
    The `|&` makes sure we capture both stdout and stderr, `tee` then writes them to the fifo and displays them. `split-window` tells tmux to create a second pane, and display the output of grep.

        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

        Tmux is a very helpful terminal multiplexer, meaning it can split your terminal into multiple panes. So, create two side by side panes, then one way of doing it is:\n
        \n
        - on the left, run `your cmd | tee >(grep ‘denied’ > error.log)`\n
        - on the right, run `tail -f error.log`\n
        \n
        The `tee` process takes it’s standard in, and writes itbto both standard out, so you see all the lines, and the path it’s been given. The `>(…)` operator runs the grep in a subprocess, and returns the path to it’s standard input pipe, so `grep` receives every line, and writes the denied lines to a log file which you display with `tail` in the other pane.\n
        \n
        Rather than using a file for error.log you could also use a named pipe in much the same way.

    Sorry for th slow answer, I’ve been away. There is a way, if it’s still useful to you:\n
    \n
    First, create a named fifo, you only need to do this once:\n
    \n
    ```\n
    \n
    <span style="color:#323232;">mkfifo logview\n
    </span>\n
    ```\n
    \n
    Run your rsync in one pane, with a filtered view in the second:\n
    \n
    ```\n
    \n
    <span style="color:#323232;">tmux new 'rsync ...options... |& tee logview' ; split-window -h 'grep "denied" logview'\n
    </span>\n
    ```\n
    \n
    Replace `…options…` with your normal rsync command line.\n
    \n
    That should give you a split view, with all the normal messages on the left, and only messages containing ‘denied’ on the right.\n
    \n
    The `|&` makes sure we capture both stdout and stderr, `tee` then writes them to the fifo and displays them. `split-window` tells tmux to create a second pane, and display the output of grep.

        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

    +url: null
    +body: """
      I want to run a command and see all of its output on the left hand side, while simultaneously searching/grepping for particular lines on the right hand side. In other words, I want a temporary vertically split screen in my CLI, ideally with scrollback on each side of the split, but where I expect the left hand side to be scrolling thousands of lines quickly, while on the right hand side is a slow accumulation of “matches” to my grep.\n
      \n
      Is this possible today? What tools would you recommend to accomplish this?\n
      \n
      EDIT: To be clear, a one-liner is preferable over learning tmux or screen, although this does motivate me to perhaps begin learning tmux.\n
      \n
      In case this is an X/Y problem: The specific command I’m trying to run is an rsync simulation (dry-run) where I want to both check that the command works, and subsequently check that there are no `denied` errors. The recommended way to do this is to run the command twice, as follows (but I want to combine it into one pass):\n
      \n
      ```\n
      \n
      <span style="color:#323232;"># first specify the "-n" parameter so rsync will simulate its operation. You should use this before you start:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/\n
      </span><span style="color:#323232;">\n
      </span><span style="color:#323232;"># check for permission denied errors in your homedir:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/ | grep denied\n

        Tmux is a very helpful terminal multiplexer, meaning it can split your terminal into multiple panes. So, create two side by side panes, then one way of doing it is:\n
        \n
        - on the left, run `your cmd | tee >(grep ‘denied’ > error.log)`\n
        - on the right, run `tail -f error.log`\n
        \n
        The `tee` process takes it’s standard in, and writes itbto both standard out, so you see all the lines, and the path it’s been given. The `>(…)` operator runs the grep in a subprocess, and returns the path to it’s standard input pipe, so `grep` receives every line, and writes the denied lines to a log file which you display with `tail` in the other pane.\n
        \n
        Rather than using a file for error.log you could also use a named pipe in much the same way.

    Sorry for th slow answer, I’ve been away. There is a way, if it’s still useful to you:\n
    \n
    First, create a named fifo, you only need to do this once:\n
    \n
    ```\n
    \n
    <span style="color:#323232;">mkfifo logview\n
    </span>\n
    ```\n
    \n
    Run your rsync in one pane, with a filtered view in the second:\n
    \n
    ```\n
    \n
    <span style="color:#323232;">tmux new 'rsync ...options... |& tee logview' ; split-window -h 'grep "denied" logview'\n
    </span>\n
    ```\n
    \n
    Replace `…options…` with your normal rsync command line.\n
    \n
    That should give you a split view, with all the normal messages on the left, and only messages containing ‘denied’ on the right.\n
    \n
    The `|&` makes sure we capture both stdout and stderr, `tee` then writes them to the fifo and displays them. `split-window` tells tmux to create a second pane, and display the output of grep.

        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

    +body: """
      I want to run a command and see all of its output on the left hand side, while simultaneously searching/grepping for particular lines on the right hand side. In other words, I want a temporary vertically split screen in my CLI, ideally with scrollback on each side of the split, but where I expect the left hand side to be scrolling thousands of lines quickly, while on the right hand side is a slow accumulation of “matches” to my grep.\n
      \n
      Is this possible today? What tools would you recommend to accomplish this?\n
      \n
      EDIT: To be clear, a one-liner is preferable over learning tmux or screen, although this does motivate me to perhaps begin learning tmux.\n
      \n
      In case this is an X/Y problem: The specific command I’m trying to run is an rsync simulation (dry-run) where I want to both check that the command works, and subsequently check that there are no `denied` errors. The recommended way to do this is to run the command twice, as follows (but I want to combine it into one pass):\n
      \n
      ```\n
      \n
      <span style="color:#323232;"># first specify the "-n" parameter so rsync will simulate its operation. You should use this before you start:\n

      Sorry for th slow answer, I’ve been away. There is a way, if it’s still useful to you:\n
      \n
      First, create a named fifo, you only need to do this once:\n
      \n
      ```\n
      \n
      <span style="color:#323232;">mkfifo logview\n
      </span>\n
      ```\n
      \n
      Run your rsync in one pane, with a filtered view in the second:\n
      \n
      ```\n
      \n
      <span style="color:#323232;">tmux new 'rsync ...options... |& tee logview' ; split-window -h 'grep "denied" logview'\n
      </span>\n
      ```\n
      \n
      Replace `…options…` with your normal rsync command line.\n
      \n
      That should give you a split view, with all the normal messages on the left, and only messages containing ‘denied’ on the right.\n
      \n
      The `|&` makes sure we capture both stdout and stderr, `tee` then writes them to the fifo and displays them. `split-window` tells tmux to create a second pane, and display the output of grep.

        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

    +url: null
    +body: """
      I want to run a command and see all of its output on the left hand side, while simultaneously searching/grepping for particular lines on the right hand side. In other words, I want a temporary vertically split screen in my CLI, ideally with scrollback on each side of the split, but where I expect the left hand side to be scrolling thousands of lines quickly, while on the right hand side is a slow accumulation of “matches” to my grep.\n
      \n
      Is this possible today? What tools would you recommend to accomplish this?\n
      \n
      EDIT: To be clear, a one-liner is preferable over learning tmux or screen, although this does motivate me to perhaps begin learning tmux.\n
      \n
      In case this is an X/Y problem: The specific command I’m trying to run is an rsync simulation (dry-run) where I want to both check that the command works, and subsequently check that there are no `denied` errors. The recommended way to do this is to run the command twice, as follows (but I want to combine it into one pass):\n
      \n
      ```\n
      \n
      <span style="color:#323232;"># first specify the "-n" parameter so rsync will simulate its operation. You should use this before you start:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/\n
      </span><span style="color:#323232;">\n
      </span><span style="color:#323232;"># check for permission denied errors in your homedir:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/ | grep denied\n

          Tmux is a very helpful terminal multiplexer, meaning it can split your terminal into multiple panes. So, create two side by side panes, then one way of doing it is:\n
          \n
          - on the left, run `your cmd | tee >(grep ‘denied’ > error.log)`\n
          - on the right, run `tail -f error.log`\n
          \n
          The `tee` process takes it’s standard in, and writes itbto both standard out, so you see all the lines, and the path it’s been given. The `>(…)` operator runs the grep in a subprocess, and returns the path to it’s standard input pipe, so `grep` receives every line, and writes the denied lines to a log file which you display with `tail` in the other pane.\n
          \n
          Rather than using a file for error.log you could also use a named pipe in much the same way.

      Sorry for th slow answer, I’ve been away. There is a way, if it’s still useful to you:\n
      \n
      First, create a named fifo, you only need to do this once:\n
      \n
      ```\n
      \n
      <span style="color:#323232;">mkfifo logview\n
      </span>\n
      ```\n
      \n
      Run your rsync in one pane, with a filtered view in the second:\n
      \n
      ```\n
      \n
      <span style="color:#323232;">tmux new 'rsync ...options... |& tee logview' ; split-window -h 'grep "denied" logview'\n
      </span>\n
      ```\n
      \n
      Replace `…options…` with your normal rsync command line.\n
      \n
      That should give you a split view, with all the normal messages on the left, and only messages containing ‘denied’ on the right.\n
      \n
      The `|&` makes sure we capture both stdout and stderr, `tee` then writes them to the fifo and displays them. `split-window` tells tmux to create a second pane, and display the output of grep.

        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

    +url: null
    +body: """
      I want to run a command and see all of its output on the left hand side, while simultaneously searching/grepping for particular lines on the right hand side. In other words, I want a temporary vertically split screen in my CLI, ideally with scrollback on each side of the split, but where I expect the left hand side to be scrolling thousands of lines quickly, while on the right hand side is a slow accumulation of “matches” to my grep.\n
      \n
      Is this possible today? What tools would you recommend to accomplish this?\n
      \n
      EDIT: To be clear, a one-liner is preferable over learning tmux or screen, although this does motivate me to perhaps begin learning tmux.\n
      \n
      In case this is an X/Y problem: The specific command I’m trying to run is an rsync simulation (dry-run) where I want to both check that the command works, and subsequently check that there are no `denied` errors. The recommended way to do this is to run the command twice, as follows (but I want to combine it into one pass):\n
      \n
      ```\n
      \n
      <span style="color:#323232;"># first specify the "-n" parameter so rsync will simulate its operation. You should use this before you start:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/\n
      </span><span style="color:#323232;">\n
      </span><span style="color:#323232;"># check for permission denied errors in your homedir:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/ | grep denied\n

          Tmux is a very helpful terminal multiplexer, meaning it can split your terminal into multiple panes. So, create two side by side panes, then one way of doing it is:\n
          \n
          - on the left, run `your cmd | tee >(grep ‘denied’ > error.log)`\n
          - on the right, run `tail -f error.log`\n
          \n
          The `tee` process takes it’s standard in, and writes itbto both standard out, so you see all the lines, and the path it’s been given. The `>(…)` operator runs the grep in a subprocess, and returns the path to it’s standard input pipe, so `grep` receives every line, and writes the denied lines to a log file which you display with `tail` in the other pane.\n
          \n
          Rather than using a file for error.log you could also use a named pipe in much the same way.

      Sorry for th slow answer, I’ve been away. There is a way, if it’s still useful to you:\n
      \n
      First, create a named fifo, you only need to do this once:\n
      \n
      ```\n
      \n
      <span style="color:#323232;">mkfifo logview\n
      </span>\n
      ```\n
      \n
      Run your rsync in one pane, with a filtered view in the second:\n
      \n
      ```\n
      \n
      <span style="color:#323232;">tmux new 'rsync ...options... |& tee logview' ; split-window -h 'grep "denied" logview'\n
      </span>\n
      ```\n
      \n
      Replace `…options…` with your normal rsync command line.\n
      \n
      That should give you a split view, with all the normal messages on the left, and only messages containing ‘denied’ on the right.\n
      \n
      The `|&` makes sure we capture both stdout and stderr, `tee` then writes them to the fifo and displays them. `split-window` tells tmux to create a second pane, and display the output of grep.

        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

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

    +url: null
    +body: """
      I want to run a command and see all of its output on the left hand side, while simultaneously searching/grepping for particular lines on the right hand side. In other words, I want a temporary vertically split screen in my CLI, ideally with scrollback on each side of the split, but where I expect the left hand side to be scrolling thousands of lines quickly, while on the right hand side is a slow accumulation of “matches” to my grep.\n
      \n
      Is this possible today? What tools would you recommend to accomplish this?\n
      \n
      EDIT: To be clear, a one-liner is preferable over learning tmux or screen, although this does motivate me to perhaps begin learning tmux.\n
      \n
      In case this is an X/Y problem: The specific command I’m trying to run is an rsync simulation (dry-run) where I want to both check that the command works, and subsequently check that there are no `denied` errors. The recommended way to do this is to run the command twice, as follows (but I want to combine it into one pass):\n
      \n
      ```\n
      \n
      <span style="color:#323232;"># first specify the "-n" parameter so rsync will simulate its operation. You should use this before you start:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/\n

      </span><span style="color:#323232;"># check for permission denied errors in your homedir:\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

    +url: null
    +body: """
      I want to run a command and see all of its output on the left hand side, while simultaneously searching/grepping for particular lines on the right hand side. In other words, I want a temporary vertically split screen in my CLI, ideally with scrollback on each side of the split, but where I expect the left hand side to be scrolling thousands of lines quickly, while on the right hand side is a slow accumulation of “matches” to my grep.\n
      \n
      Is this possible today? What tools would you recommend to accomplish this?\n
      \n
      EDIT: To be clear, a one-liner is preferable over learning tmux or screen, although this does motivate me to perhaps begin learning tmux.\n
      \n
      In case this is an X/Y problem: The specific command I’m trying to run is an rsync simulation (dry-run) where I want to both check that the command works, and subsequently check that there are no `denied` errors. The recommended way to do this is to run the command twice, as follows (but I want to combine it into one pass):\n
      \n
      ```\n
      \n
      <span style="color:#323232;"># first specify the "-n" parameter so rsync will simulate its operation. You should use this before you start:\n

    +url: null
    +body: """
      I want to run a command and see all of its output on the left hand side, while simultaneously searching/grepping for particular lines on the right hand side. In other words, I want a temporary vertically split screen in my CLI, ideally with scrollback on each side of the split, but where I expect the left hand side to be scrolling thousands of lines quickly, while on the right hand side is a slow accumulation of “matches” to my grep.\n
      \n
      Is this possible today? What tools would you recommend to accomplish this?\n
      \n
      EDIT: To be clear, a one-liner is preferable over learning tmux or screen, although this does motivate me to perhaps begin learning tmux.\n
      \n
      In case this is an X/Y problem: The specific command I’m trying to run is an rsync simulation (dry-run) where I want to both check that the command works, and subsequently check that there are no `denied` errors. The recommended way to do this is to run the command twice, as follows (but I want to combine it into one pass):\n
      \n
      ```\n
      \n
      <span style="color:#323232;"># first specify the "-n" parameter so rsync will simulate its operation. You should use this before you start:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/\n
      </span><span style="color:#323232;">\n
      </span><span style="color:#323232;"># check for permission denied errors in your homedir:\n

      I want to run a command and see all of its output on the left hand side, while simultaneously searching/grepping for particular lines on the right hand side. In other words, I want a temporary vertically split screen in my CLI, ideally with scrollback on each side of the split, but where I expect the left hand side to be scrolling thousands of lines quickly, while on the right hand side is a slow accumulation of “matches” to my grep.\n
      \n
      Is this possible today? What tools would you recommend to accomplish this?\n
      \n
      EDIT: To be clear, a one-liner is preferable over learning tmux or screen, although this does motivate me to perhaps begin learning tmux.\n
      \n
      In case this is an X/Y problem: The specific command I’m trying to run is an rsync simulation (dry-run) where I want to both check that the command works, and subsequently check that there are no `denied` errors. The recommended way to do this is to run the command twice, as follows (but I want to combine it into one pass):\n
      \n
      ```\n
      \n
      <span style="color:#323232;"># first specify the "-n" parameter so rsync will simulate its operation. You should use this before you start:\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

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

    +url: null
    +body: """
      I want to run a command and see all of its output on the left hand side, while simultaneously searching/grepping for particular lines on the right hand side. In other words, I want a temporary vertically split screen in my CLI, ideally with scrollback on each side of the split, but where I expect the left hand side to be scrolling thousands of lines quickly, while on the right hand side is a slow accumulation of “matches” to my grep.\n
      \n
      Is this possible today? What tools would you recommend to accomplish this?\n
      \n
      EDIT: To be clear, a one-liner is preferable over learning tmux or screen, although this does motivate me to perhaps begin learning tmux.\n
      \n
      In case this is an X/Y problem: The specific command I’m trying to run is an rsync simulation (dry-run) where I want to both check that the command works, and subsequently check that there are no `denied` errors. The recommended way to do this is to run the command twice, as follows (but I want to combine it into one pass):\n
      \n
      ```\n
      \n
      <span style="color:#323232;"># first specify the "-n" parameter so rsync will simulate its operation. You should use this before you start:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/\n
      </span><span style="color:#323232;">\n
      </span><span style="color:#323232;"># check for permission denied errors in your homedir:\n
      </span><span style="color:#323232;">rsync -naP --exclude-from=rsync-homedir-local.txt /home/$USER/ $BACKUPDIR/ | grep denied\n
