Hi, see man rename:

DESCRIPTION
"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/' *
