Since Perl merely acts as a front end to mv and other command line UNIX commands...
Not exactly -- Perl calls the underlying rename system call directly, so there's some efficiency gained in not having to fork and exec. Nonetheless, it's unlikely that reducing that overhead is going to make a significant dent in your execution time.

If you have time on your hands and are good at Perl, the only way to be sure is to write the program and measure. But I'm guessing it won't make a big difference.
