Rename/Duplicate PyroCMS Module Bash Script

rename_module.sh

#!/bin/bash

##
# Script created by David Lewis ([email protected]) for PyroCMS
# This script will rename an existing (core) CMS module and duplicate it into the 
# addons/shared_addons/modules directory, while renaming it and all file contents to 
# match
#
# Usage: ./rename_module.sh "old_module" "new_module"
# 
# TODO:
# 1. Ideally, this would work for all plugins/widgets/addons/modules, regardless
#   of location.
# 2. Error-check input and ensure it comes in as lowercase alpha-numeric with 
#   underscores

I have created a fork of this for use on Mac OS X 10.7.5 with Bash 3.2.48(1)-release
