A while ago I made a tiny function in my ~/.zshrc to download a video from the link in my clipboard. I use this nearly every day to share videos with people without forcing them to watch it on whatever site I found it. What’s a script/alias that you use a lot?

# Download clipboard to tmp with yt-dlp
tmpv() {
  cd /tmp/ && yt-dlp "$(wl-paste)"
}

    This is dumb lol but

    update = “sudo apt update && sudo apt upgrade”

    Exchange apt for whatever package manager you use, optionally add “&& flatpak upgrade”. If you really want to live on the edge throw a -y in there as well

      Mine is a bit longer and includes automatically removing unused dependencies: alias update='sudo apt update && sudo apt upgrade && flatpak update && sudo apt autoremove --purge && flatpak remove --unused --delete-data && notify-send '\''update done'\'''

      I have a similar one as well for debian-based operating systems…

      dist-upgrade() {
          sudo apt update && sudo apt dist-upgrade && sudo apt autoremove
      }
      

      To get this to work without a password, i dropped a file in /etc/sudoers.d that allows anyone in the sudo group to sudo apt without a password.

      root@tux:~# cat /etc/sudoers.d/apt

      # Cmnd alias specification
      Cmnd_Alias COMMANDS = /usr/bin/apt, /usr/bin/apt-get, /usr/bin/dpkg
      
      # Use apt commands without a password
      %sudo ALL=(root) NOPASSWD: COMMANDS

    Wouldn’t say I use it often, but this thing resolves a domain name to an IP address:

    function resolve() {
      case $1 in
        -4)
          getent ahostsv4 $2 | grep STREAM | head -n 1 | cut -d ' ' -f 1
          ;;
        -6)
          getent ahostsv6 $2 | grep STREAM | head -n 1 | cut -d ' ' -f 1
          ;;
        -p)
          getent hosts $2 | head -n 1 | cut -d ' ' -f 1
          ;;
        *)
          getent ahosts $1 | grep STREAM | cut -d ' ' -f 1 | sort -u      
          ;;
      esac
    }
    

    All my aliases are just default arguments for programs or shorthands for my other scripts, most of which are specific for my setup.

    This is a very good argument for ffmpeg and ffprobe, by the way:

    alias ffmpeg="ffmpeg -hide_banner"
    alias ffprobe="ffprobe -hide_banner"

      Do you often (if at all) run into conflicts with the .. alias? I can’t think of any case on top of my head, but it feels a bit sketchy. The more than 2 dots however I imagine is pretty safe.

        No, never. I rarely use the 4 dots, but 2 and 3, all the time.

        Tab completion shows this:

        $ ..<Tab><Tab>
        ../   ...   ....

    It’s not terribly exciting but I find myself using this a lot:

    #!/bin/sh
    
    echo "$*" | sed -e "s/x/*/g" | bc -l
    

    Just a little shorthand for bc that allows me to write “x” instead of “*” to avoid shell expansion nonsense. I put it in ~/.local/bin/= so I can e.g. just write = 17+4x5. Combined with a Quake-style terminal this is much faster than launching a calculator app. It’s a script instead of an alias so it works regardless of the shell I’m currently using.

    The call to bc -l could be replaced with one to qalc -t if you know qalc to be present on the system .

    Not an alias, but expanding -h to --help has been very useful in cases where the program just prints “see --help for options” when you just use -h

    I use glola from oh-my-zsh every day to see an overview of my projects

    Ans ns/nss is very convenient to run one-off commands with software I don’t already have installed!

    Oh and cdt = cd $(mktemp -d) is nice to have when you just need a temporary clean directory to do something quick

    in my .gitconfig i have

    [alias]
    	glg = log --oneline --decorate --all --graph
    

    This allows me to get a quick overview over all branches with pushes that are recent enough for most cases.

      I was unfamiliar with the decorate flag, but I can’t see any difference after trying.

      I will say this is one command I absolutely refuse to create an alias for.

      I have force committed to memory the command: git log --graph --remotes --all (and the variation with the --oneline flag appended to the end if needed) so I can use it anywhere.

      It’s the one command I can’t live without.

    I am using Music Player Daemon, and I use the following script to turn gPodder into a client. My music is in ~/Music and I put the podcasts in ~/Music/Podcasts. The script works for both streaming or downloaded podcasts.

    [~]$ cat bin/mpcut.sh
    #!/bin/bash
    if [ "$(echo "$1" | cut -b-4)" = "http" ]; then
        /usr/bin/mpc pause
        /usr/bin/mpc insert "$1"
        /usr/bin/mpc toggle
        /usr/bin/notify-send -i gpodder "$1 inserted to next spot in playlist."
    else
        /usr/bin/mpc pause
        /usr/bin/mpc add "Podcasts/$(echo "$1" | cut -d"/" -f6-)"
        /usr/bin/mpc toggle
        /usr/bin/notify-send -i gpodder "$(echo "$1" | cut -d"/" -f7-)" "added to end of playlist."
    fi
    

    Audio Player in gPodder preferences is set to this: /home/christopher/bin/mpcut.sh %F

    I have an application shortcut Super-G set to this in xfce4-keyboard-settings: env GTK_THEME=Adwaita-dark GPODDER_HOME=/home/christopher/.config/gPodder/ GPODDER_DOWNLOAD_DIR=/home/christopher/Music/Podcasts/ /usr/bin/gpodder

    or you could use an alias: alias gpodder='GTK_THEME=Adwaita-dark GPODDER_HOME=/home/christopher/.config/gPodder/ GPODDER_DOWNLOAD_DIR=/home/christopher/Music/Podcasts/ /usr/bin/gpodder --verbose'

    Simple bash function that runs something fully detached even if its parent closes, and is not dependent on any software feature such as bash’s disown
