Git pre-push hook that shows changes and ask for confirmation when pushing to production repo.

README

Whenever you push to remote that has "production" in its name,
this hook will show commits and changes and then ask for confirmation.

Copy or symlink to .git/hooks/pre-push.

Deployment by pushing code to remote github repo are very convenient
but prone to accidents. I wanted something that would force me to
review what's being pushed.

My Bash-foo is very limited to suggestions for improvements are very welcome.

pre-push

#!/bin/bash

if [[ "$1" =~ "production" ]]; then
  read -a array
  pushed_ref=${array[1]}
  remote_ref=${array[3]}

  echo
  echo "# Commits:"
  git log --oneline -5 $remote_ref...$pushed_ref

  echo
  echo "# Files changed:"
  git diff --name-only $remote_ref $pushed_ref

  echo
  echo
  read -p "You're about to push to production, are you sure? [AFFIRMATIVE|NEGATIVE] " -r < /dev/tty
  echo
  if [[ $REPLY = 'AFFIRMATIVE' ]]; then
    exit 0
  else
    exit 1
  fi
else
  exit 0 # push will execute
fi

Excellent!!! Work perfect.
