Cleaning up local Git repositories

clean-up-git.sh

// Check there's nothing that hasn't been committed and synced
git status;

// Push to the remote to make sure it has a record of any local commits/branches
git push;

// Now, prune your local repos
git remote prune origin;

// And clean up any tracked branches not in the list of remotes (https://stackoverflow.com/questions/13064613/how-to-prune-local-tracking-branches-that-do-not-exist-on-remote-anymore)
// WANRING: `-D` _force_ deletes your branches, so do a dry run if you want to make sure nothing important is going bye-bye
git branch -r | awk '{print $1}' | egrep -v -f /dev/fd/0 <(git branch -vv | grep origin) | awk '{print $1}' | xargs git branch -D
