renamespace.bash

#!/bin/bash
# This simple script takes two arguments <search> and <replace> and:
# 1. Copies all folders found that match <search> into <replace>, renaming files as required
# 2. Searches through the contents of all files for <search> and replaces it with <replace>

# This script is *not* currently recursive. It won't renamespace modules or themes within other modules or themes.

# This is great for re-namespacing a drupal installation profile from something like "template" to the name of the project.
# Be aware that there's no safety cap on this, if you do something stupid like using the name of a Drupal hook function as your search
# string you'll obviously break things.

# IMPORTANT: I highly recommend that you have your project checked into some kind of version control like git BEFORE running this script
