Linux

alias gl='git log'
alias server-name-here='ssh server-name-here'

I have a bunch of the server aliases. I use those and gl the most.

i use

alias kimg='kitty +kitten icat' 

to display images in my terminal pretty simple but nice

jmpd(jump directory): fuzzy finds and opens directory with fzf

# fish shell
function jmpd
    set _selection $(fzf --walker=dir);
    if test -n "$_selection"
        cd "$_selection";
    end
end

I made this one to find binaries in NixOs and other systems

get_bin_path() {
        paths=${2:-$PATH}
        for dr in $(echo $paths | tr ':' '\n') ; do
                if [ -f "$dr/$1" ] ; then
                        echo "$dr/$1"
                        return 0
                fi
        done
        return 1
}

Then I made this one to, if I have a shell o opened inside neovim it will tell the neovim process running the shell to open a file on it, instead of starting a new process

_nvim_con() {
        abs_path=$(readlink --canonicalize "$@" | sed s'| |\\ |'g)
        $(get_bin_path nvim) --server $NVIM --remote-send "<ESC>:edit $abs_path<CR>"
        exit
}

# start host and open file
_nvim_srv() {
        $(get_bin_path nvim) --listen $HOME/.cache/nvim/$$-server.pipe $@
}

if [ -n "$NVIM" ] ; then
        export EDITOR="_nvim_con"
else
        export EDITOR="_nvim_srv"
fi

Lastly this bit: which if it detects a file and a line number split by a : it will open the file and jump to the line

_open() {
        path_parts=$(readlink --canonicalize "$@" | sed s'| |\\ |'g | sed 's/:/\t/' )
        file=$(echo "$path_parts" | awk ' { print $1 }' )
        line=$(echo "$path_parts" | awk ' { print $2 }' )

        if [ -n "$line" ] ; then
                # has line number
                if [ -n "$NVIM" ] ; then
                        $(get_bin_path nvim) --server $NVIM --remote-send "<ESC>:edit $file<CR>:+$line<CR>"
                        exit
                else
                        $(get_bin_path nvim) --listen $HOME/.cache/nvim/$$-server.pipe $file "+:$line"
                fi
        else
                $EDITOR $file
        fi
}

alias nvim="_open"

all of my bash config is here

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....

Here is on that I actually don't use, but want to use it in scripts. It is meant to be used by piping it. It's simple branch with user interaction. I don't even know if there is a standard program doing exactly that already.

# usage: yesno [prompt]
# example:
#   yesno && echo yes
#   yesno Continue? && echo yes || echo no
yesno() {
    local prompt
    local answer
    if [[ "${#}" -gt 0 ]]; then
        prompt="${*} "
    fi
    read -rp "${prompt}[y/n]: " answer
    case "${answer}" in
    [Yy0]*) return 0 ;;
    [Nn1]*) return 1 ;;
    *) return 2 ;;
    esac
}

Hey OP, consider using $XDG_RUNTIME_DIR instead of /tmp. It's now the more proper place for these kinds of things to avoid permission issues, although I'm sure you're on a single user system like most people. I have clipboard actions set to download with yt-dlp :)

My favorite aliases are:

alias dff='findmnt -D -t nosquashfs,notmpfs,nodevtmpfs,nofuse.portal,nocifs,nofuse.kio-fuse'

alias lt='ls -t | less'

On MacOS, to open the current directory in Finder: alias f='open -a Finder .'

I use Clevis to auto-unlock my encrypted root partition with my TPM; this means when my boot partition is updated (E.G a kernel update), I have to update the PCR register values in my TPM. I do it with my little script /usr/bin/update_pcr:

#!/bin/bash
clevis luks regen -d /dev/nvme1n1p3 -s 1 tpm2

I run it with sudo and this handles it for me. The only issue is I can't regenerate the binding immediately after the update; I have to reboot, manually enter my password to decrypt the drive, and then do it.

Now, if I were really fancy and could get it to correctly update the TPM binding immediately after the update, I would have something like an apt package shim with a hook that does it seamlessly. Honestly, I'm surprised that distributions haven't developed robust support for this; the technology is clearly available (I'm using it), but no one seems to have made a user-friendly way for the common user to have TPM encryption in the installer.

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 my grep lr ~/.bashrc is alias lr="ls -lrth"

For docker: I’m not following best practices. I have a giant docker compose file for my entire home lab, this is how I update things:

alias dockpull="docker compose pull"
alias dockup="docker compose up -d --remove-orphans"

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) &
}

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

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

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'

Not exactly a single script, but I use scm breeze for git stuff. Has a ton of QoL features for working with git

https://github.com/scmbreeze/scm_breeze

g-push

git push origin `git branch --show`

I alias traditional stuff to better, usually drop-in versions of that thing on computers that have the better thing. I often forget which systems have the better thing, so this helps me get the better experience if I was able to install it at some point. For example I alias cat to bat, or top to htop, or dig to drill, etc.

I wrote this suite of scripts a few years ago and still use them to:

1. Boot into Ventoy and select a Debian Live environment
2. Optional: connect a storage device (local partition, USB drive, etc) for persistent storage
3. Modify cfg/cfg.sh if it's the first time using the tool
4. Run setup.sh to configure the environment into a familiar/productive state

The tools are flexible on hardware (more directed toward x64 systems at this time), and I (almost) never have to worry about OS upgrades. Just boot into a newer live OS image once it's ready. They are still a work-in-progress and still have a few customizations that I should abstract for more general use, but it's FOSS in case anyone has merge requests, issues, suggestions, etc.
