A bash script that can be used in prepush Git hook to warn when pushing changes to master or an otherwise protected branch

prepush.sample

protected_branch='master'
current_branch=$(git symbolic-ref HEAD | sed -e 's,.*/\(.*\),\1,')

# define bash colors to display
yellow='\033[0;33m'
red='\033[0;31m'
green='\033[0;32m'
no_color='\033[0m'


if [ $protected_branch = $current_branch ]; 
then echo "${yellow}You're about to push to $protected_branch, is that what you intended? [y|n]${no_color}" 
    read  < /dev/tty 
    if echo $REPLY | grep -E '[^Yy]$' > /dev/null; then
        echo "${red}This commit has been aborted.${no_color}"
        exit 1 # push will not execute if there is not explicit 'Y' typed
    else 
        echo "${green}This commit is proceeding...${no_color}"
        exit 0 # push will execute
    fi
else 
	exit 0 # push will execute
fi
