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)"
}

    alias clip='xclip -selection clipboard'

    When you pipe to this, for example ls | clip, it will stick the output of the command ran into the clipboard without needing to manually copy the output.

    I try to organise my data in the cleanest way possible, with the less double possible etc… I end up using a lot of symbolic links. When doing maintenance, sometimes I want to navigate in the “unlogical” way the data are organized, but the PWD variable is not necessarily very cooperative. This alias is really useful in my case :

    alias realwd='cd -P .'

    Here is an example :

    $ echo $PWD  
/home/me  
$ cd Videos/Torrents/  
$ echo $PWD  
/home/me/Videos/Torrents  
$ realwd  
$ echo $PWD  
/home/me/data/Torrents/Video

    I also do some X application, compositor and WM development, and I have a few aliases to simplify tasks like copying from an Xorg session to an Xnest (and the other way around), or reload the xrandr command from my .xinitrc without duplicating it.

    alias screenconf='$(grep -o "xrandr[^&]*" ~/.xinitrc)'  
alias clip2xnext='xclip -selection clip -o -display :0 | xclip -selection clip -i -display :1'  
alias clip2xorg='xclip -selection clip -o -display :1 | xclip -selection clip -i -display :0'

    I have an alias for using MPV+yt-dlp with my firefox cookies :

    alias yt="mpv --ytdl-raw-options='cookies-from-browser=firefox'"

    I can’t stand too long lines of text on my monitor, particularly when reading manpages, so I set the MANWIDTH env variable.

    # Note : if you know that *sometimes* your terminal will be smaller than 80 characters  
# refer to that https://wiki.archlinux.org/title/Man_page  
export MANWIDTH=80

    I use null-pointers a lot, with a shorthand.

    # Note: env.sh actually provide other helpful aliases on their homepage  
function envs.sh() {  
	if [ $# != 1 ]; then  
		1>&2 printf "Error, need one argument.\n"  
		return 1  
	fi  
	curl -F'file=@'"$1" https://envs.sh/  
}

    The usual fake editor in my path, so that browsers and other applications open Vim the correct way.

    #!/bin/sh  
# st_vim.sh - executable in my ~/.local/bin  
# for example in firefox's about:config :  
#   - view_source.editor.path : set to the value of $(which st_vim.sh)  
#   - view_source.editor.external : set to true  

st -- $EDITOR "$*"

    My .xinitrc is quite classical, I still have this in it (setup for dwm’s title bar, people usually install much complicated programs) :

    while true; do xsetroot -name "$(date +"%d %H:%M")"; sleep 60; done &

    I also have a lot of stupid scripts for server and desktop maintenance, disks cleaning etc… those are handy but are also very site-specific, let me know if your interested.

    I wrote a script called please. You input please followed by any other command (e.g. please git clone, please wget blahblah) and a robotic voice will say “affirmative,” then the command will run, and when it completes, the robotic voice reads out the exit code (e.g. “completed successfully” or “failed with status 1” etc.)

    This is useful for when you have a command that takes a long time and you want to be alerted when it’s finished. And it’s a gentleman.

    I often want to know the status code of a curl request, but I don’t want that extra information to mess with the response body that it prints to stdout.

    What to do?

    Render an image instead, of course!

    curlcat takes the same params as curl, but it uses iTerm2’s imgcat tool to draw an “HTTP Cat” of the status code.

    It even sends the image to stderr instead of stdout, so you can still pipe curlcat to jq or something.

    #!/usr/bin/env zsh

stdoutfile=$( mktemp )
curl -sw "\n%{http_code}" $@ > $stdoutfile
exitcode=$?

if [[ $exitcode == 0 ]]; then
  statuscode=$( cat $stdoutfile | tail -1 )

  if [[ ! -f $HOME/.httpcat$statuscode ]]; then
    curl -so $HOME/.httpcat$statuscode https://http.cat/$statuscode
  fi

  imgcat $HOME/.httpcat$statuscode 1>&2
fi

cat $stdoutfile | ghead -n -1

exit $exitcode

    Note: This is macOS-specific, as written, but as long as your terminal supports images, you should be able to adapt it just fine.

      With how many new Linux users we get recently, I don’t like this joke at all without a disclaimer. Yes yes, its your own fault if you execute commands without knowing what it does. But that should not punish someone by deleting every important personal file on the system.

      In case any reader don’t know, rm is a command to delete files and with the option rm -r everything recursively will be searched and deleted on the filesystem. Option -f (here bundled together as -rf) will never prompt for any non existing file. The / here means start from the root directory of you system, which in combination with the recursive option will search down everything, home folder included, and find every file. Normally this is protected todo, but the extra option --no-preserve-root makes sure this command is run with the root / path.

      Haha I know its funny. Until someone loses data. Jokes like these are harmful in my opinion.

    on most of my systems I get tired of constantly lsing after a cd so I combine them:

    cd(){
    cd $1 && ls
}

    (excuse if this doesn’t work, I am writing this from memory)

    I also wrote a function to access docker commands quicker on my Truenas system. If passed nothing, it enters the docker jailmaker system, else it passes the command to docker running inside the system.

    docker () {
        if [[ "$1" == "" ]]; then
                jlmkr shell docker
                return
        else
                sudo systemd-run --pipe --machine docker docker "$@"
                return
        fi
}

    I have a few similar shortcuts for programs inside jailmaker and long directories that I got sick of typing out.

        That’s very good.

        Generalization and line feed customisation :

        function sloooower() {
	BASE_INTERVAL=${1:-0.05}
	RET_ADD_INTERVAL=${2:-0.1}
	CHAR_ADD_INTERVAL=${3:-0}
	while IFS= read -r -n1 char; do
		if [[ -z "$char" ]]; then
			sleep "${RET_ADD_INTERVAL}"
			printf "\n"
		else
			sleep "${CHAR_ADD_INTERVAL}"
			printf "%s" "$char"
		fi
		sleep "${BASE_INTERVAL}"
	done
}
alias sl='ls | sloooower'
