This way, the script will only work on subdirectories.

it will only work on files that are not "plain files", but will still include unwanted entities like symlinks, named pipes, sockets, block and character files.

Instead of next if -f $_; which is not that accurate, it is much better to use the already suggested next unless -d $_; which does the trick of doing no more and no worse of skipping everything that's not a directory.
