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
# Author: Rob Miller <>
# 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# local master is out of date.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 [ "$MERGED_ON_REMOTE" ]; then
echo "The following remote branches are fully merged and will be removed:"
read -p "Continue (y/N)? "
if [ "$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!"
