Prune merged branches from git local and remote

prune

#!/bin/bash

# This will prune merged and deleted branches from your git repository.
# It assumes you're on a "master" branch tracking the origin you like.
#
# To run it, you need git (duh), perl, cut, grep and xargs. Pretty standard stuff.

git=/usr/bin/git

master=$(git branch | grep "^\*" | cut -f2 -d\ )
origin=$(git branch -vv | grep "^\*" | cut -f2 -d\[ | cut -f1 -d\] | cut -d/ -f1)

# Clean up local clones of remotes
$git fetch --all -p 

# Delete local merged
$git branch --merged | grep -v "^\*" | xargs -r -n 1 $git branch -D 

# Delete merged branches on origin
$git branch -a --merged | grep -v "^\*" | grep "remotes/${origin}/" | cut -f2-3 -d/ | grep -v "${master}" | perl -e 'while (<>) { s#/# :#; print; }' |  xargs -r -n 2 $git push
