githook to validate newly created branch names

Question

Does anyone know if there\'s a githook that will hook into the creation of a branch in order to reject the branch name before it\'s actually created?

I currently use com

Answer 1

There is not (and to some extent it can't be controlled: branch names are transferred across the network during fetch and push, via refspecs, and refspecs are somewhat limited).

There is a git command, git check-ref-format; its documentation describes what Git allows. (Branch names are simply any reference that starts with refs/heads/.)
