spring clean your git repos!

gistfile1.sh

# remove any bad refs
git remote prune origin

# pipe into bash and auto-delete any branches that have been merged into master!
git log master --pretty=format:'%d' | grep '^ (origin' | tr -d ' ()' | sed 's/origin\//git push origin :/'

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

@raggi that might delete master...running on my repo gives:

  origin :HEAD -> origin/master
  origin :master

I missed a backslash in the grep -v, that's why :)
