alias ..='cd ..'

mkcd() { mkdir -p “$1” && cd “$1”; }

Make a directory and immediately cd into it. I rarely make a directory and not cd into it.

alias ta="tmux attach -t"

alias ll=“ls - l”

My most-used, by far, for decades.

alias clearswap='sudo swapoff -a && sudo swapon -a'
alias grep='grep --color=auto'
alias ls='ls --color=auto --group-directories-first'
alias la='ls -lAh --color=auto --group-directories-first'
alias timestamp='date +%Y-%m-%dT%H-%M-%S'

I always set these because I’ve been burned too many times:

Turn on interactive mode for dangerous commands

alias cp='cp -iv'
alias mv='mv -iv'
alias rm='rm -iv'

Not exactly an alias but a short script. First, get git-revise which is a replacement for git rebase, and fzf if for some reason you don’t have it yet. Then make a script in your ~/.local/bin called git-f or whatever you’d like:

#!/bin/bash
REF=${1:-origin/main}  # adjust to your favorite trunk branch name
COMMIT=$(git log --pretty=oneline ${REF}.. \
         | fzf --preview "git show -p --stat {+1}" | cut -d' ' -f1)
if [ -n "$COMMIT" ]; then
    exec git revise "$COMMIT"
else
    exit 1
fi

Now hack away in a branch, make some commits, and at some point you will realize you want to modify an earlier commit. Use git add -p to add the relevant lines, but then instead of making a fixup commit just type git f and pick the target commit from the list.

alias clearswap='sudo swapoff -a && sudo swapon -a

alias reload=‘source ~/.bashrc’

scan_local() {

 local_ip=$(ip addr show wlan0 | grep "inet " | awk '{print $2}' | awk -F '/' '{print $1}')

 sudo nmap -sn "$local_ip/24"

}

alias x=“exit”

become="sudo su -"
pb="ansible-playbook"

alias upd=“yay -Syu --devel”

alias cleanup=“yay -Qdtq | yay -Rns-”

alias mirror=“sudo reflector --verbose --country ‘United States’ --protocol https --latest 15 --sort rate --save /etc/pacman.d/mirrorlist && sudo eos-rankmirrors”

I use this function to launch GUI apps from the shell without occupying that shell or cluttering it with their output:

nown() {
        if [ -n "$1" ]
        then
                nohup $@ &> /dev/null & disown
        else
                echo "Don't give me a null command dumbass."
        fi
}

Technically not aliases but I have these in my ~/.bash_aliases so…

bind ‘“\e[A”: history-search-backward’
bind ‘“\e[B”: history-search-forward’

Type a few letters and press up/down arrow to scroll through matching history entries.

Also…

alias s=“cd -”

It’s like Alt+Tab for CLI.

dc=“docker-compose” saves me soooo much time!

alias et='emacsclient -ct'
alias ec='emacsclient -cn'
alias make='make --warn-undefined-variables'
