Git: Prevent pushing to master

pre_push

# For any repository you want to protect, you need to create a new file called pre-push in the .git/hooks directory.
# Also check that the pre-push file is executable (run chmod +x .git/hooks/pre-push on the command line) and try again :)

# Add following code snippets to $YOUR_REPO/.git/hooks/pre-push file
# Then run chmod +x $YOUR_REPO/.git/hooks/pre-push


#!/bin/bash
 
PROTECTED_BRANCH='master'  
CURRENT_BRANCH=$(git symbolic-ref HEAD | sed -e 's,.*/\(.*\),\1,')
 
if [ $PROTECTED_BRANCH = $CURRENT_BRANCH ]  
then  
  read -p "You're about to push master, is that what you intended? [y|n] " -n 1 -r < /dev/tty
  echo
  if echo $REPLY | grep -E '^[Yy]$' > /dev/null
  then
    exit 0

  exit 1
else  
  exit 0
