You could look at the File::Compare module here http://search.cpan.org/~rgarcia/perl-5.10.0/lib/File/Compare.pm But you should consider your data first. If you simply need to know whether a two files are identical or not you should consider calculating a checksum. If you need to know /where/ files are different then it would speed things up dramatically if they were sorted.
