Yeah, in Perl, it'd be:

for $old (<*>) {
	($new = $old) =~ y/A-Z/a-z/;
	rename($old,$new) || warn "Cannot rename $old to $new ($!)";
}

But, if you don't have Perl (shame on you!), here's the /bin/sh (et. al.)
solution:

for old in *
do
	mv $old `echo $old | tr A-Z a-z`
done

Of course, with this solution, you are firing off four processes for
each file, but it still works.  Might take a while for 200 names.

Just another Perl hacker,
