Git post commit hook to remind me not to add console.log statements

gistfile1.ebuild

​​#!/bin/sh
# Detects a forgotten console.log statement
# Could be made a pre-commit hook forcing the issue, but then adding jQuery.js becomes cumbersome

if $(git show HEAD | grep -q '^\+.*console\.log')
then
  RED='\e[1;31m'
  NC='\e[0m'
  echo -e  "${RED}WARNING:${NC}"
  echo " You left in a console.log statement in your code, please reconsider commiting this"
