While writing your app, you’ll likely need to delete old, merged code branches. It’s important to maintain a healthy, clean codebase, which will boost your development team’s productivity. They won’t need to wade through obsolete branches in search of the right one, and they’ll be much less likely to make costly mistakes.

Here’s my one-line script for removing merged branches from remote (run it when you are on the latest master branch):

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

It simply lists all remote branches that have been merged to your current branch (that’s why you need to be on master), skips master itself (grep -v master), removes “origin/” suffix and then passes everything to git push --delete origin.
