Delete all git branches that have been merged

Question

I have a lot of branches and I want to delete all of them. Is there a way of deleting them all at a time?

Answer 1

To delete all branches on remote that are already merged:

git branch -r --merged | grep -v master | sed 's/origin\//:/' | xargs -n 1 git push origin

In more recent versions of Git

git branch -r --merged | grep -v master | sed 's/origin\///' | xargs -n 1 git push –delete origin

Answer 2

To delete all local branches that are already merged into the currently checked out branch:

git branch --merged | egrep -v "(^\*|master|dev)" | xargs git branch -d

master and dev are excluded in case they are an ancestor.

You can delete a merged local branch with:

git branch -d branchname

If it's not merged, use:

git branch -D branchname

To delete it from the remote in old versions of Git use:

git push origin :branchname

In more recent versions of Git use:

git push --delete origin branchname

Once you delete the branch from the remote, you can prune to get rid of remote tracking branches with:

git remote prune origin

or prune individual remote tracking branches, as the other answer suggests, with:

git branch -dr branchname
