rename from to files... on *nix.

"I wouldn't even use Perl. I'd just say "rename *.bob *.fred" on the command line."

But you are using Perl, since rename is written in Perl :-)

Update:Many people seem to vote without reading the followups, so, here it is:

RENAME(1) Perl Programmers Reference Guide RENAME(1)

NAME
rename - renames multiple files

SYNOPSIS
rename [ -v ] perlexpr [ files ]

DESCRIPTION
"rename" renames the filenames supplied according to the
rule specified as the first argument. The perlexpr argu?
ment 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/' *

Hello again

Apparently we're talking about 2 different renames:
