Here's the script I use to remove my merged branches, both remote and local. Disclaimer: Don’t blame me if you use this script to remove something you wanted do keep. Maybe add the `-n` flag to `git push` while you’re trying out how the script works. If in trouble, read [man git-reflog](http://git-scm.com/docs/git-reflog).

gistfile1.sh

git checkout master
git pull
git remote prune origin
git branch -r --merged | grep bquorning | awk -F'/' '{ print ":" $2 "/" $3 }' | xargs git push origin
git branch --merged | grep -v "\* master" | xargs git branch -d

# That was actually a somewhat simplified version. Here's what I really use:

git checkout master && git pull && (git remote prune origin && git branch -r --merged | grep bquorning | awk -F'/' '{ print ":" $2 "/" $3 }' | xargs git push origin) & ; git branch --merged | grep -v "\* master" | xargs git branch -d
