Original Answer from 5-Jan-10
From Chapter 3 of Pro Git by Scott Chacon:
Deleting Remote Branches
Suppose you’re done with a remote branch — say, you and your collaborators are finished with a feature and have merged it into your remote’s master branch (or whatever branch your stable codeline is in). You can delete a remote branch using the rather obtuse syntax git push [remotename] :. If you want to delete your serverfix branch from the server, you run the following:
$ git push origin :serverfix
- [deleted] serverfix
Boom. No more branch on your server. You may want to dog-ear this page, because you’ll need that command, and you’ll likely forget the syntax. A way to remember this command is by recalling the git push [remotename] [localbranch]:[remotebranch] syntax that we went over a bit earlier. If you leave off the [localbranch] portion, then you’re basically saying, “Take nothing on my side and make it be [remotebranch].”
I issued git push origin :bugfix and it worked beautifully. Scott Chacon was right—I will want to dog ear that page (or virtually dog ear by answering this on StackOverflow).
