Clean up merged git branches

cleanup_git.sh

#!/bin/zsh

# Do merged git branches clutter up your local machine?
# This handy script can automatically clean them up for you.

# To install - put the script somewhere on the filesystem and add a source command to your .bashrc / .zshrc
# e.g. - 'source ~/code/scrapbook/cleanup_git.sh'

# When the script is sourced you will get two commands -
# "gitclean" - delete merged branches in current folder (with prompt)
# "gitcleanall" - iterate all my project directories running "gitclean" in each of them

# To change your project dir, edit this line - "export PROJECT_DIR=$HOME/code"

# This script is written for zsh (i.e. macOS), for bash/linux you might need to change the read command
# on line 29 to 'read -p "These branches will be deleted locally - are you sure? " reply'
