Hi, see man rename:


	"rename" renames the filenames supplied
	according to the rule specified as the first argument.  The
	perlexpr argument is a Perl expression which is expected to
	modify the $_ string in Perl for at least some of the
	filenames specified.  If a given filename is not modified by
	the expression, it will not be renamed.  If no filenames are
	given on the command line, filenames will be read via
	standard input.

       	For example, to rename all files matching "*.bak" to strip
       	the extension, you might say

	       rename 's/\e.bak$//' *.bak

       To translate uppercase names to lower, you'd use

	       rename 'y/A-Z/a-z/' *


... don't touch the bang bang fruit
