Mass Rename is a simple pair of shell scripts which make it easier to move, 
rename, or copy multiple files at once. It is intended mainly as an automatic 
and simple way to rename multiple files with a customizable prefix and a 
progressive number. It is also possible to modify the rename format simply 
by editing one of the scripts. It is easy, complete, and efficient, and was 
written only in sh code.
