# Find and replace text in multiple files
# http://www.24hourapps.com/2009/03/linux-tips-17-find-and-replace-text-in.html

# Multiple file find and replace is a rarely used, but an extremely time saving, ability of
# Linux that I cannot live without. It can be achieved by chaining a few commands together
# to get the list of files you want to change (find), make sure the files contain the strings
# you want to replace (grep), and do the replacements (sed).

# Lets say we have a lot of code that uses the function registerUser that was implemented when
# there was only one class of users, but now another class of users need to access the system
