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 "$(wl-paste)"
}
alias fucking='sudo'
(my coworkers often usedprettyplease
instead)I often want to know the status code of a
curl
request, but I don’t want that extra information to mess with the response body that it prints to stdout.What to do?
Render an image instead, of course!
curlcat
takes the same params ascurl
, but it uses iTerm2’simgcat
tool to draw an “HTTP Cat” of the status code.It even sends the image to stderr instead of stdout, so you can still pipe
curlcat
tojq
or something.#!/usr/bin/env zsh stdoutfile=$( 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
this one is clean asl
LOVE this
I have a few interesting ones.
Download a video:
alias yt="yt-dlp -o '%(title)s-%(id)s.%(ext)s' "
Execute the previous command as root:
alias please='sudo $(fc -n -l -1)'
Delete all the Docker things. I do this surprisingly often:
alias docker-nuke="docker system prune --all --volumes --force"
This is a handy one for detecting a hard link
function is-hardlink { count=$(stat -c %h -- "${1}") if [ "${count}" -gt 1 ]; then echo "Yes. There are ${count} links to this file." else echo "Nope. This file is unique." fi }
I run this one pretty much every day. Regardless of the distro I’m using, it Updates All The Things:
function up { if [[ $(command -v yay) ]]; then yay -Syu --noconfirm yay -Yc --noconfirm elif [[ $(command -v apt) ]]; then sudo apt update sudo apt upgrade -y sudo apt autoremove -y fi flatpak update --assumeyes flatpak remove --unused --assumeyes }
I maintain an aliases file in GitLab with all the stuff I have in my environment if anyone is curious.
Ooooou I got a couple :3
This one is just a basic mirror fixing thing cuz sometimes I go a while without updating pacman:
alias fixpkg='rate-mirrors --protocol https arch | sudo tee /etc/pacman.d/mirrorlist && sudo pacman -Syy'
This function I made to create virtual audio sinks so I can route audios via qpw and play earrape into discord calls if I want XD
create_vsink() { local sink_name=${1:-vsink} # Default sink name is 'vsink' if no input is provided local description=${2:-"Virtual Sink"} # Default description pactl load-module module-null-sink sink_name="$sink_name" sink_properties=device.des> echo "Virtual sink '$sink_name' created with description '$description'." }
Simple parser function I made that makes a whole repo using my git key so it’s not just locally created I kinda forgot why I made it tbh:
git_clone() { local url="${1#https://}" # Remove "https://" if present git clone "https://$git_key@$url" }
Awesome mpv function I made that allows for real time pitch+speed shifting via hotkeys and is flexible with extra parameters and shit:
mpv_pitch() { if [[ -z "$1" ]]; then echo "Usage: mpv_pitch <file> [mpv-options]" return 1 fi local file="$1" shift mpv --input-conf=/dev/stdin "$file" "$@" <<EOF SHIFT+RIGHT add audio-pitch-correction 0; add pitch 0.01; add speed 0.01 # Decrease pit> SHIFT+LEFT add audio-pitch-correction 0; add pitch -0.01; add speed -0.01 # Increase pit> EOF }
Automatic audio router for firefox audio streams that uses the aforementioned create_sink function to make a specific sink that I can use carla on to mix and make cool shit out of haha
firefox_crush() { create_vsink CrunchSink "CrunchSink" firefox --name firefox-vc & (while true; do SINK_INPUT_ID=$(pactl list sink-inputs short | grep "firefox" | awk '{print $1}') if [[ -n "$SINK_INPUT_ID" ]]; then pactl move-sink-input "$SINK_INPUT_ID" CrunchSink break fi sleep 0.25 done) & }
I have started my daily drawing journey which i still am bad at it. To create a new .kra files files every day I use this
#/usr/bin/bash days=$(</var/home/monika/scripts/days) echo "$days" file_name=/var/home/monika/Pictures/Art/day$days.kra if [ -f $file_name ]; then echo file is present else if [[ $days%7 -eq 0 ]]; then echo "Week completed" fi cp "/var/home/monika/scripts/duplicate.kra" $file_name flatpak run org.kde.krita $file_name echo $(($days + 1)) >/var/home/monika/scripts/days fi
Monika from ddlc? :O
it’s somewhat vibe coded but the one i probably use the most is this one to swap between speakers and headset. the device name to look for is just put directly in there, it’d take some adjustment to run it on different machines. this is in my .bashrc:
# switch sinks toggle_audio() { # Find headset sink ID dynamically headset_id=$(pactl list sinks short | grep "Plantronics" | awk '{print $1}') # Find speakers sink ID dynamically speakers_id=$(pactl list sinks short | grep "pci-0000_05_00.6" | awk '{print $1}') # Get current default sink current_sink=$(pactl get-default-sink) # Get current sink ID current_id=$(pactl list sinks short | grep "$current_sink" | awk '{print $1}') # Toggle between the two if [ "$current_id" = "$headset_id" ]; then pactl set-default-sink "$speakers_id" echo "Switched to speakers (Sink $speakers_id)" else pactl set-default-sink "$headset_id" echo "Switched to headset (Sink $headset_id)" fi }
generally i try not to use too many custom things because for work i regularly work on all kinds of different servers and i’ve just been too lazy to set up some solution to keep it all in sync. someday…
#Create a dir and cd into it mkcd() { mkdir -p "$@" && cd "$@"; }
I’ve stolen a bunch of Git aliases from somewhere (I don’t remember where), here are the ones I ended up using the most:
g=git ga='git add' gau='git add --update' gcfu='git commit --fixup' gc='git commit --verbose' 'gc!'='git commit --verbose --amend' gcmsg='git commit --message' gca='git com gd='git diff' gf='git fetch' gl='git pull' gst='git status' gstall='git stash --all' gstaa='git stash apply' gp='git push' 'gpf!'='git push --force-with-lease' grb='git rebase' grba='git rebase --abort' grbc='git rebase --continue'
I also often use
ls='eza' md='mkdir -p' mcd() { mkdir -p "$1" && cd "$1" }
And finally some Nix things:
b='nix build' bf='nix build -f' bb=nix build -f .' s='nix shell' sf='nix shell -f' snp='nix shell np#' d='nix develop' df='nix develop -f'
Because using docker can sometimes cause ownership issues if not properly configured in your docker-compose.yml, I just added an alias to ~/.zshrc to rectify that.
-edit- Only run this script in your user owned directories, e.g. anything from ~/ (or /home/<your_username>) you might otherwise cause ownership issues for your system.
## Set ownership of files/folders recursively to current user alias iownyou="sudo chown -R $USER:$GROUP"
Ooooh tmpv is a smart name for your little tool. I may steal it lol
My desktop text editor has an autosave feature, but it only works after you’ve manually saved the file. All I wanted is something like the notes app on my phone, where I can jot down random thoughts without worrying about naming a new file. So here’s the script behind my text editor shortcut, which creates a new text file in ~/.drafts, names it with the current date, adds a suffix if the file already exists, and finally opens the editor:
#!/bin/bash name=/home/defacto/.drafts/"`date +"%Y%m%d"`"_text if [[ -e "$name" || -L "$name" ]] ; then i=1 while [[ -e "$name"_$i || -L "$name"_$i ]] ; do let i++ done name="$name"_$i fi touch -- "$name" pluma "$name" #replace pluma with your editor of choice
Here are probably the most useful ones. I prefer for
rm
to be interactive so I don’t accidentally delete something important and formkdir
to create a parent directory if necessary.alias rm='rm -i' alias mkdir='mkdir -p' alias podup='podman-compose down && podman-compose pull && podman-compose up -d'
This extract function (which I didn’t make myself, I got it from when I was using nakeDeb) has been pretty useful too.
function extract() { if [ -f $1 ] ; then case $1 in *.tar.bz2) tar xvjf $1 ;; *.tar.gz) tar xvzf $1 ;; *.bz2) bunzip2 $1 ;; *.rar) unrar x $1 ;; *.gz) gunzip $1 ;; *.tar) tar xvf $1 ;; *.tbz2) tar xvjf $1 ;; *.tgz) tar xvzf $1 ;; *.zip) unzip $1 ;; *.Z) uncompress $1 ;; *.7z) 7z x $1 ;; *.xz) unxz $1 ;; *) echo "'$1' cannot be extracted via >extract<" ;; esac else echo "'$1' is not a valid file" fi }
To answer your question realistically I did
history | sed "s/.* //" | sort | uniq -c | sort -n
which returned as first non standard command
lr
which from mygrep lr ~/.bashrc
isalias lr="ls -lrth"
A few days ago I posted a one-liner to do the same thing too. It will resolve aliases from your history and expand program paths to its fullpath. I thought you might be interested: https://beehaw.org/post/20584479
type -P $(awk '{print $1}' ~/.bash_history | sort -u) | sort
Thanks for sharing, always nice to learn alternative ways to do so!
I’ll share 3:
alias chx='chmod +x' alias rr='rm -rf' alias shrug="echo '¯\_(ツ)_/¯'"
i also have the chmod one, but mine is named just x:
alias x='chmod +x'
I also have the
yt-dlp "$(wl-paste)"
one, but its build around a custom script. So sharing it here makes no sense. Its funny how often we do same thing in different ways (extracting or creating archives in example). Often aliases get development into function and then they turn into scripts. For some of the more simple aliases, here a selection:alias f='fastfetch -l none' alias vim='nvim' alias baloo='balooctl6'
I replaced rm with trash-put, just in case I realize I need some files that I removed down the line.
alias rm='trash-put'
Official author don’t recommend it due to different semantics. But honestly for my own personal use case its fine for me.
Also I like to alias xclip:
alias clippy='xclip -selection clipboard' # cat things.txt | clippy
Official author don’t recommend it due to different semantics. But honestly for my own personal use case its fine for me.
I don’t recommend that either. If you get used to that ‘rm’ doesn’t actually remove files and then your alias is missing for whatever reason it’ll bite you in the rear at some point. And obviously the same hazard goes with a ton of other commands too.
Little tip: In case you need to use
rm
directly, even with the alias in effect, you can put a backslah in front of the command to use its original meaning:\rm filename
oooh so does that apply to any command/user binary on the system?
I’m not sure what you mean with the question. If you have any alias like
alias rm='ls -l'
in your .bashrc in example, then you cannot use the original commandrm
anymore, as it is aliased to something else. I’m speaking about the terminal, when you enter the command. However, if you put a backslash in front of it like\rm
in the terminal, then the alias for it is ignored and the original command is executed instead.Edit: Made a more clear alias example.
Oh ty ty that answers my question! I am fairly new to being a poweruser on linux so I may have worded that wrong XD
