A script for cleaning up Git repositories; it deletes branches that are fully merged into `origin/master`, prunes obsolete remote tracking branches, and as an added bonus will replicate these changes on the remote.

git-cleanup-repo

#!/bin/bash

# Author: Rob Miller <[email protected]>
# Adapted from the original by Yorick Sijsling

git checkout master &> /dev/null

# Make sure we're working with the most up-to-date version of master.
git fetch

# Prune obsolete remote tracking branches. These are branches that we
# once tracked, but have since been deleted on the remote.
git remote prune origin

# List all the branches that have been merged fully into master, and
# then delete them. We use the remote master here, just in case our
# local master is out of date.
git branch --merged origin/master | grep -v 'master$' | xargs git branch -d

# Now the same, but including remote branches.
MERGED_ON_REMOTE=`git branch -r --merged origin/master | sed 's/ *origin\///' | grep -v 'master$'`

if [ "$MERGED_ON_REMOTE" ]; then
	echo "The following remote branches are fully merged and will be removed:"
	echo $MERGED_ON_REMOTE

	read -p "Continue (y/N)? "
	if [ "$REPLY" == "y" ]; then
		git branch -r --merged origin/master | sed 's/ *origin\///' \
			| grep -v 'master$' | xargs -I% git push origin :% 2>&1 \
			| grep --colour=never 'deleted'
		echo "Done!"
	fi
fi

What is the best way to run the first chunk of code, just copy and paste into bash?

@MacDoogle

1. Put the code in a file called git-cleanup-repo
2. Put that file in your path (e.g. in /usr/local/bin)
3. Make sure it's executable (chmod +x /usr/local/bin/git-cleanup-repo)
4. In a repository, run git cleanup-repo and it will run this script

If you want to do that in one go, run this:

$ curl https://gist.githubusercontent.com/robmiller/5133264/raw/1ee11ff5bda524e0aa4074cac95ac98c5c48181a/git-cleanup-repo > /usr/local/bin/git-cleanup-repo && chmod +x /usr/local/bin/git-cleanup-repo

then:

$ cd path/to/your/project
$ git cleanup-repo

Thanks!!

Sorry still a little unclear. I am on Windows 10 if that helps and using Azure DevOps repos.
What file extension should I save this as, aka what type of file?
Since it does not ask me what repo I presume it works in whatever repo you execute it in?

@MacDoogle this is a bash script (look at the first line of the script), you can add the .sh extension to it.
