Git pre-push hook to confirm pushing to master

README.md

Git pre-push hook

It will check if current branch is master, then ask a confirmation, in case of 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
protected_branch='master'  
current_branch=$(git symbolic-ref HEAD | sed -e 's,.*/\(.*\),\1,')

if [ $protected_branch = $current_branch ]  
then  
  
    echo -en "\033[31mYou're about to push master, is that what you intended? [y|n] \033[0m"
    echo -en "\033[1m"
    read -n 1 -r < /dev/tty
    echo -en "\033[0m"
    
    echo
    if echo $REPLY | grep -E '^[Yy]$' > /dev/null
    then
        exit 0 # push will execute
    fi
    exit 1 # push will not execute
else  
    exit 0 # push will execute
fi 

It's on my fork, not really an array but should be sufficient nevertheless: https://gist.github.com/mosra/19abea23cdf6b82ce891c9410612e7e1
