Handy git pre-compile hook to prevent yourself from committing passwords

pre-commit

#!/bin/sh

# Save this file in your {repoRoot}/.git/hooks directory with the filename 
# 'pre-commit' (no extension), and replace the passwords with your own. Don't 
# worry: this file does not get committed. It exists only where you place it. 
# Fair warning, though: you are essentially saving your password in plaintext. 
# Ensure that you have other security measures in place to protect your data; 
# e.g., drive encryption, station locking, etc.
