Rename/Duplicate PyroCMS Module Bash Script

rename_module.sh

#!/bin/bash

##
# Modified version of https://gist.github.com/3680107
# 
# Tested for use on Mac OS X 10.7.5 with Bash 3.2.48(1)-release
#
# Old module needs to be in system/cms/modules and a single word (Ex: blogs not site_blogs)
##

##
# Script created by David Lewis (highwayoflife@gmail.com) 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 receive LOADS of "sed: can't read" errors when I use this. It does copy and rename the module to /news/ but it does not rename references to blog inside the files.

Worked for me. Had many "in-place editing only works for regular files" errors on sed while running the script but the files, as it seems, where search and replaced correctly by the script. (Mac Os X Yosemite, GNU bash, version 3.2.53(1)-release (x86_64-apple-darwin14))
