global-hook

1. Enable git templates:
git config --global init.templatedir '~/.git-templates'
This tells git to copy everything in ~/.git-templates to your per-project .git/ directory when you run git init

2. Create a directory to hold the global hooks:
mkdir -p ~/.git-templates/hooks

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

4. Make sure the hook is executable.
chmod a+x ~/.git-templates/hooks/pre-push

5. Re-initialize git in each existing repo you'd like to use this in:
git init

NOTE if you already have a hook defined in your local git repo, this will not overwrite it.

local-project-hook

1. Copy your script to /path/to/your/project/.git/hooks

2. Remember to keep the name of hook consistent(eg. pre-commit, pre-push, post-commit) - no file extension

3. Remember to chmod a+x on a hook to be executable

pre-push

#!/bin/bash
#
# Check for debugging statements before pushing your code.
#

# List of function names to search for in regex format
FUNCTIONS="binding\.pry|console\.log|dupa"

# If any functions are found as executable, prevent the push.
EXITONFAIL=true

echo "Running the check against debugger functions in your code..."
CMD="grep -Enr --exclude=\*.{png,jpg,jpeg,gif} --exclude-dir={.git,tmp,log,public} \"$FUNCTIONS\""

echo "$CMD"

if [[ -n "$CMD" ]]; then
  echo "Debugging functions were found in your code!"

  eval "$CMD"

  if [[ $EXITONFAIL == true ]]; then
    echo "Changes were not pushed."
    exit 1;
  else
    echo "You may want to clean these up. Changes were pushed anyway."
    exit 0;

else
  echo "No debugging functions were found. Nice job, Ace!";
  exit 0;
