Updating a Git branch that is not checked outEdit

If you're on branch foo and want to make branch bar point at the HEAD of foo without having to first checkout bar, you can use:

$ git branch -f bar HEAD

Note that HEAD is actually the default, so the above can be simplified to:

$ git branch -f bar
