Gitclean - a simple shell script (aimed at macos paths but you can adapt for linux) to automate the pruning of deleted git branches

gitclean-setup

# Create the script and place it in ~/.local/bin/gitclean, setting it +x
echo '#!/usr/bin/env bash

# Update remote references
git fetch --prune

# Identify and delete local branches that no longer exist on remote
git branch -vv | grep "gone]" | awk "{print \$1}" | xargs git branch -D
' > ~/.local/bin/gitclean && chmod +x ~/.local/bin/gitclean

# Add the path to your $path
echo 'export PATH="~/.local/bin:$PATH" >> .zshrc

# Change the paths as you need!
