       Description: In this article, you will learn how to use git hooks to
       prevent a branch from being pushed.
       
       # Introduction
       
       I was looking for a simple way to prevent pushing a specific git
       branch.  A few searches on the Internet didn't give me good results, so
       let me share a solution.
       
       # Hooks
       
       Hooks are scripts run by git at a specific time, you have the "pre-"
       hooks before an action, and "post-" hooks after an action.
       
       We need to edit the hook "pre-push" that happens at push time, before
       the real push action taking place.
       
       Edit or create the file .git/hooks/pre-push:
       
       ```shell
       #!/bin/sh
       
       branch="$(git branch --show-current)"
       
       if [ "${branch}" = "private" ]
       then
           echo "Pushing to the branch ${branch} is forbidden"
           exit 1
       fi
       ```
       
       Mark the file as executable, otherwise it won't work.
       
       In this example, if you run "git push" while on the branch "private",
       the process will be aborted.
