in thread Renaming Sub Dir/Files.

That should read 
    rename $_, lc($_) or warn "Could not rename $_ to @{[lc($_)]}: $!\
+n";

In case the target filename already exists in the directory (especially if case-sensitive filesystems are involved). Or warn instead of die. Or break lc($_) out into a variable to avoid the code interpolation. Whatever.
