rename multiple files #util

	# Rename multiple files
	# http://www.24hourapps.com/2009/03/linux-tips-10-rename-multiple-files.html

	# Renaming multiple files in Linux is surprisingly difficult given the simplistic power
	# provided by many other system commands. Unlike DOS, which provided a rename command that
	# allowed wild cards, Linux's rename/mv command is less versatile. Therefore to rename files
	# one needs to write a loop. Luckily bash helps a lot here.

	# Lets say we have in our directory a number of .txt files that we need to rename to .nfo.
	# To do this we would need to use the command:
