git: Delete All Branches but Master

By  on  

Maintenance is incredibly important in any project, but if you want to take your professionalism to the next level, you should keep your git environment in shape.  Unfortunately I'm not that guy -- I leave git branches laying around, even after they've been merged into master.  GitHub even provides a button to do the cleanup but I can't be bothered.  Not good.

When you're ready to do some real cleanup on a repository, throw this at it:

git branch | grep -v "master" | sed 's/^[ *]*//' | sed 's/^/git branch -d /' | bash

The shell command above deletes every branch in your local checkout except for master branch.  This is a dangerous script but you could always check out a given branch from a remote like GitHub if you happen to need it!

  1. The script becomes less dangerous, when it uses the

    git branch -d

    variant instead of the upper case -D. Then branches are only deleted, when they are already merged in any of the remaining branches, and no work is lost. (Also, the error messages show you, which branches have work, that has not yet landed in master.)

  2. git remote prune origin -)

    git branch | grep -v "master" | xargs git branch -d

    Thank you, this worked well for me. I first tried it with -d, which deleted some, and then decided to go for -D, which did end up deleting everything but master.
