I agree that there's no compelling reason not to just call it from system() but if you did need it in Perl code it'd be a fun challenge. I think I'd do it by reading in chunks from each file and doing an MD5 on each chunk with [cpan://Digest::MD5]. Compare the MD5s and if they're different then you've got a difference. Oh, and start by comparing file sizes!
