I have codebase of 5k lines. Most used are git commands (squash all to merge base, push to current branch, commit with format etc), work shortcuts for starting projects, time logging, startup programs. Then I have some cli interface for redo commands, size of current folders for disk pruning, abandoned project alias, os commands like brightness adjust, launch game on steam with qwert instead of dvorak keyboard, search cli history, kill with regex matching…
Just anything that I don’t want to Google twice. bash is life
