Here is an example bash script that I created for dealing with filenames
and extensions. It should be straightforward to modify it and stick it
into a for loop to do what you want.
echo 'file name ' $file
echo 'extension' $extension
echo 'root name ' $rootname
echo 'root w/o number ' $rootnonum
echo 'number ' $number
