How can I delete all Git branches which have been merged?

Question

I have many Git branches. How do I delete branches which have already been merged? Is there an easy way to delete them all instead of deleting them one by one?

Answer 1

You can add the commit to the --merged option. This way you can make sure only to remove branches which are merged into i.e. the origin/master

Following command will remove merged branches from your origin.

git branch -r --merged origin/master | grep -v "^.*master" | sed s:origin/:: |xargs -n 1 git push origin --delete 

You can test which branches will be removed replacing the git push origin --delete with echo

git branch -r --merged origin/master | grep -v "^.*master" | sed s:origin/:: |xargs -n 1 echo
