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 weather='curl wttr.in'

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 ..='cd ..'

alias ll="ls - l"

My most-used, by far, for decades.

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'

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
}

alias fuck='sudo $(fc -ln -1)'

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 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'

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”

alias ta="tmux attach -t"

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.

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

Here's my .bash_aliases file

Good luck, I'm dogshit at maintaining the comments lol

I don't use aliases. Since I use fish as a login shell, I use abbreviations. I have a lot of them configured. But I think my favorite one is yeet which expands to paru -Rcns.

I made a cool exercise some time ago: checking my top 10 used commands, to see how I can "optimize" them, and maybe create a few aliases to save a few keystrokes. Turns out I don't need that much aliases in the end:

alias v='vis' # my text editor
alias sv='doas vis'
alias ll='ls -l'

And that's pretty much it ^^ I do have a lot of scripts though, some of them being one-liners, but it makes them shell independent, which I like :)

For reference, here is my analysis of my top 10 most used commands.

edit: I do have a bunch of git aliases though for common subcommands I use. I prefer using them as git <alias> over using she'll specific aliases so I can always type "git" and not mentally think wether I need a git command or a shell alias.

*ahem

alias brb='paru -Syu --noconfirm && paru -Sc --noconfirm'

Interesting, git do support aliases too. "git st" etc What is .load.sh?

For git and working with a mix of master and main default branch repos my favourite is gsm='git switch $(git_main_branch)' to switch back to main/master
