Git - ask before commiting to master/main

how-to.md

Outcome: you push to master/main, and get asked if you want to proceed

% git push
Are you sure you want to push to "main" ? (y/n): 

Instructions from here: https://gist.github.com/ColCh/9d48693276aac50cac37a9fce23f9bda

I preferred the script here though so used that instead: https://hammad.ca/blog/2015/03/08/confirm-before-pushing-to-master-branch

To install

1. Enable git templates

git config --global init.templatedir '~/.git-templates'

2. Create a directory to hold the global hooks:

mkdir -p ~/.git-templates/hooks

3. Write your hook in ~/.git-templates/hooks

See file pre-push in this gist.

Copy it to ~/.git-templates/hooks/pre-push

4. Make it executable

chmod a+x ~/.git-templates/hooks/pre-push

5. In currently existing project, do reinit

git init

This will not overwrite existing commits, or existing hooks.

Done!

pre-push

#!/bin/bash
# Warn before pushing to protected branches
# Make script executable with chmod +x pre-push
# Bypass with git push --no-verify

BRANCH=`git rev-parse --abbrev-ref HEAD`
PROTECTED_BRANCHES="^(master|main|dev|release-*|patch-*)"

if [[ "$BRANCH" =~ $PROTECTED_BRANCHES ]]; then
  read -p "Are you sure you want to push to \"$BRANCH\" ? (y/n): " -n 1 -r < /dev/tty
  echo
  if [[ $REPLY =~ ^[Yy]$ ]]; then
    exit 0
  fi
  echo "Push aborted."
  exit 1
fi
exit 0
