That doesn't work, because you get only the filenames from readdir and not their paths. You will have to prefix "/home/costas/test/" yourself:

my $path = '/home/costas/test';

opendir (DIR, $path) or die "Can't opendir: $!";

for (readdir DIR) {
    rename("$path/$_", "$path/" . lc);
}

closedir DIR;

You need something like this:

$path = 'c:/TEST';
opendir DIR, $path or die "Cant open $path, perl says $!\n";
while (my $file = readdir DIR) {
    next if -d "$path/$file" or -l "$path/$file";
    $lc_name = lc $file;
    rename "$path/$file", "$path/$lc_name" or print STDERR "Can't rena
+me $path/$file, perl says $!\n";
}

This avoids 1)lowercasing the whole path (won't exist) and 2) skips dirs and symlinks and lc's all else

Update

Okay:
change

to:

print "profeth still\n" if /bird|devil/;

This is really bad code. First you lowercase the whole file path ensuring that any uppercase path will break this code (as when you lowercase it you will then try to write along a non existant path). Next you seem to have forgotten that '.' and '..' are not the only directories you might find. Finally you should never print unescaped arbitrary strings in HTML.

Changing:

rename("$path/$_", lc("$path/$_")) or print "Couldn't rename $file: $!\n";

To

rename("$path/$_", "$path" . lc("/$_")) or print "Couldn't rename $file: $!\n";

Would allow upper case letters in your path.
