mvgp/cpgp is a bash2 shell script that implements two commands for renaming 
or copying groups of files. The new file names are determined using a rule 
specified in the form of a pattern in the files' names to search for, and a 
string with which to replace it. For example, mvgp can be used to rename all 
files in a directory that end in .htm to end in .html instead, or if you
find a directory with 236 files that have the word "linnix" in their names, 
and you want to correct the misspellings, you can do it with a single mvgp 
command.
