Rejected custom branch

pre-commit

#!/bin/sh

# This script checks if you're pushing to any of protected branches and asks you to confirm your intention
#
# It detects even if you're trying to push to the branch with different name.
# Let's say that the current branch is 'feature' but you want to push to protected "release" branch.
# Next command push will be detected and the script will ask you to confirm the push 
# $ git push -f origin HEAD:release
#
# To skip just add "--no-verify" argument:
# $git push --no-verify origin develop
#
# Edit "protected_branches" variables if you need:
# > protected_branches=('main' 'develop' 'release')
