Git Pre-push Hook

Since I always forget how to write a git hook to prevent pushing certain branches to remotes, I'm writing this gist to, hopefully, help my future self remember...

To prevent local branch "work" from being pushed to the github remote:

#!/bin/sh

remote="$1"
url="$2"

while read local_ref local_sha remote_ref remote_sha
do
    if [ "$local_ref" = "refs/heads/work" ]
    then
        if [ "$remote" = "github" ]
        then
            echo "Can't push work branch to github"
            exit 1
        fi
    fi
done

exit 0

In order to determine the ref of the local branch you are using:

git show-ref

When done writing the file, name it pre-push, save it in .git/hooks, and be sure to make it executable.
