Ask HN: What are the best things in your shell config? Functions, aliases, etc.

What are the most useful/essential things in your shell configuration file. Be it custom function, wrappers, aliases, etc. Please provide an explanation since it isn't always obvious to others.

I have a couple of favorites (bash): # Only provide CDPATH when interactive... if [[ $- = *i* ]]; then export CDPATH=:"$HOME"/Projects/ fi `CDPATH` is great. It's like having z, j or zoxide installed for configurable paths. While it doesn't fully replace the former, it provides a lot of the useful functionality for me. _cleanup_files() { # Cleanup files local OFFENDERS=( "$HOME"/.java "$HOME"/.oracle_jre_usage "$HOME"/.pki "$HOME"/.wget-hsts "$HOME"/.xsession-errors ... ) for FILE in "${OFFENDERS[@]}"; do if [[ -e "$FILE" ]]; then trash-put "$FILE" fi done } # Prompt export PROMPT_COMMAND=_cleanup_files There are certain files that get created from various apps that I run that aren't really useful (font caches, etc). Try as I might, I can't get them into appropriate XDG-style locations. I could wrap them in boxxy, but this seems simpler. I put them in the trash in case something blew up and I need to recover it.

I have `git fsync` which pulls and deletes all the local branches when the remote branch is deleted. fsync = !git pull --rebase && git fetch -p && git branch -vv | grep ': gone]' | awk '{print $1}' | xargs git branch -D This is probably my most-used alias on my machine, by far.

I always alias rm, mv, cp, ln to -i. Also, gt, gtt, gl, ga, gc, gu, gp, gd, gd2 for git status -s, status, log, add, commit, pull, push, diff, diff to rev. All with useful (to me) flags. My prompt looks like this: \n [<status>] user@site [<cwd>]\n $ So that I see where I am, all commands line up, the last status is obvious and also there’s never this: $ cat nonewline.txt Oops no newline$ _ My .inputrc always contains https://stackoverflow.com/a/1030206 https://stackoverflow.com/a/1030206
