use File::Find;

find (sub {
    my $lc = lc ($_);
    system ("mv $File::Find::dir/$_ $File::Find::dir/$lc");
}, $dir);

# where $dir contains the directory you want to recurse
# to lowercase files... you can actually pass a list of dirs
# to find ()


BTW, use at your own risk.  I don't imagine it messing
up too bad, but be warned I haven't tested it.

hope this helps,
