For his usecase of funky i use ~/.bash_aliases, that way i can easily share them between machines. Eg to quickly add a new one: alias als="nvim $HOME/.bash_aliases && source $HOME/.bash_aliases"

Be careful with quoting though, got myself into a situation where every new terminal asked for the root password. Shellcheck found the reason quickly.

(edit) Another benefit is that those aliases abstract over differences of invocation on different distros. Here are some examples:

# PACKAGE MANAGEMENT

alias pcl="sudo zypper cc && sudo zypper purge-kernels"

alias pin="sudo zypper install -y"

alias pla="zypper search"

alias pli="zypper packages --installed-only | rg "

alias plu="zypper list-updates && zypper list-patches"

alias pre="sudo zypper remove"

alias pup="far too long" # upgrade all packages and ask for confirmation

alias pups="far too long + shutdown" # upgrade all packages without confirmation && shut down

# QUICK EDITS

alias als="nvim ~/.alias && source ~/.alias"

alias brc="nvim ~/.bashrc && source ~/.bashrc"

alias egr="sudo nvim /etc/default/grub && sudo update-grub"

alias fst="sudo nvim /etc/fstab"

alias pro="nvim ~/.profile && source ~/.profile"

# QUICK MOVEMENTS

alias ..="cd .."

alias ...="cd ../.."

alias ....="cd ../../.."

alias sc="shellcheck"

# SYSTEMD

alias sden="sudo systemctl enable --now"

alias sdls="sudo systemctl --type=service"

alias sds="sudo systemctl start"

# VIM

alias nrc="cd ~/.config/nvim/ && nvim init.lua"

alias nv="nvim"

alias scratch="nvim scratch.txt"

Instead of creating aliases for .., I use this:

  function ..() { 
    for i in $(seq 1 $1); do cd ..; done 
  }

which enables

  ..    # up 1 dir
  .. 2  # up 2 dirs
  .. 42 # up 42 dirs

Clever. Never seen that idea before.

That's amazing.

This might be a better alternate to preserve functionality of `cd -`

  function ..() {
    cd $(printf '../%.0s' $(seq 1 $1))
  }

Mmh, what do you mean with "preserve"...? `cd -` works like a charm for me.

"cd -" changes to the previous working directory. Your function calls cd multiple times, so calling "cd -" won't bring the user to the previous working directory they expect. ozym4nd145's function only calls cd once.

Aah, now I see. Awesome, I'll try that out. Thank you.

With Zsh, I am using:

    # Expand ... to ../..
    function vbe-expand-dot-to-parent-directory-path() {
      case $LBUFFER in
        (./..|* ./..) LBUFFER+='.' ;; # In Go: "go list ./..."
        (..|*[ /=]..) LBUFFER+='/..' ;;
        (*) LBUFFER+='.' ;;
      esac
    }
    zle -N vbe-expand-dot-to-parent-directory-path
    bindkey "." vbe-expand-dot-to-parent-directory-path
    bindkey -M isearch "." self-insert

Wow, this is complex... but interesting, thank you :-) I use zsh, too.

I made a slightly different thing:

If you are on

  /home/user/projects/app/src/handlers/

and you want to go to `app/`, you'll do:

  > up src

Or give name of any other child folder/file of `app/`. So if `.git` exists in `app/`,

  > up .git

would work too.

I made it for Fish shell: https://gist.github.com/ajitid/81a4993be410586c038f8b3fc140b...

I used to alias .. etc., but then found that Fish shell has helpful commands and behaviours for directory navigation built in:

> Note that the shell will attempt to change directory without requiring cd if the name of a directory is provided (starting with ., / or ~, or ending with /).

> https://fishshell.com/docs/current/cmds/cd.html

So these all work without the cd by default with Fish:

../

../../

~

~/path/to/folder

cdh is also very useful. It shows a history of recent directories with a keyed prompt to jump to a directory.

https://fishshell.com/docs/current/cmds/cdh.html

I’m also a heavy user of aliases and can’t see how I’d use funky. Behavior dependent on a current directory is rarely a good idea, and when it is, you can just create an explicit shell ./script

Funny, never occurred to me to make shortcuts out of .., I like that

You can put sudo in an alias!? [mindblown.gif]
