    tldr is great. Basically a crowd-sourced alternative to man with much more concise entries. Example:

    $ tldr dhcpcd

  DHCP client.
  More information: <https://roy.marples.name/projects/dhcpcd>.

  Release all address leases:

      sudo dhcpcd --release

  Request the DHCP server for new leases:

      sudo dhcpcd --rebind

    clear because apparently I am too scatterbrained to comprehend more than one full page of text in the terminal

      I like using CRTL+L to clear. It’s nice because you can have a command typed out and still be able to press CTRL+L to clear the screen and keep the command typed out.

          100 tabs is in mobile. I don’t even scroll back to clutter my brain but its there. Tabs are history for me… So I use firefox focus and if there is anything important, i open with firefox.

          What script are you reffering to? To log all output? I don’t wanna store that but need an assurance that its there till i close terminal window lol

    I went a little overboard and wrote a one-liner to accurately answer this question

    history|cut -d " " -f 5|sort|uniq -c|sort -nr|head -5

    Note: history displays like this for me 20622 2023-02-18 16:41:23 ls I don’t know if that’s because I set HISTTIMEFORMAT='%F %T ' in .bashrc, or if it’s like that for everyone. If it’s different for you change -f 5 to target the command. Use -f 5-7 to include flags and arguments.

    My top 5 (since last install)

       2002 ls
   1296 cd
    455 hx
    427 g
    316 find

    g is an alias for gitui. When I include flags and arguments most of the top commands are aliases, often shortcuts to a project directory.

    Not to ramble, but after doing this I figured I should alias the longest, most-used commands (even aliasing ls to l could have saved 2002 keystrokes :P) So I wrote another one-liner to check for available single characters to alias with:

    for c in a b c d e f g h i j k l m n o p q r s t u v w x y z; do [[ ! $(command -v $c) ]] && echo $c; done

    In .bash_aliases I’ve added alias b='hx ${HOME}/.bash_aliases' to quickly edit aliases and alias r='source ${HOME}/.bashrc' to reload them.

    tldr because I am too impatient to read through man pages or google the exact syntax for what I want to do.

      There are exactly three kinds of manpages:

      1. Way too detailed
      2. Not nearly detailed enough
      3. There is no manpage

      I will take 1 any day over 2 or 3. Sometimes I even need 1, so I’m grateful for them.

      But holy goddamn is it awful when I just want to use a command for aguably its most common use case and the flag or option for that is lost in a crowd of 30 other switches or buried under some modal subcommand. grep helps if you already know the switch, which isn’t always.

      You could argue commands like this don’t have “arguably most common usecases”, so manpages should be completely neutral on singling out examples. But I think the existence of tl;dr is the counterargument.

      Tangent complaint: I thought the Unix philosophy was “do one thing, and do it well”? Why then do so many of these shell commands have a billion options? Mostly /s but sometimes it’s flustering.

    Since nobody has said yet, I use screen pretty heavily. Want to run a long running task, starting it from your phone? Run screen to create a detachable session then the long running command. You can then safely close out of your terminal or detach with ctrl a, d and continue in your terminal doing something else. screen -r to get back to it.

      Also, screen can connect to an UART device or serial or anything that offers up a TTY

      How does screen / tmux work when detached from a session, how does it keep the session alive (both when running locally, and while ssh:ing to a server)? Is there a daemon involved?

      I Always forget to run screen first, so I just rely heavily on dtach

    pv (Pipe Viewer) is a command line tool to view verbose information about data streamed/piped through it. The data can be of any source like files, block devices, network streams etc. It shows the amount of data passed through, time running, progress bar, percentage and the estimated completion time.
