Perhaps write a shell script that runs from cron?
I would do something like this:
Put the file size (or better yet, the md5sum) in a file somewhere
Each time the shell script runs (say twice a day from cron), it checks to make sure the list is the same. If it's the same, the script exits. If it's different, it calls the perl script, then updates it's comparison file...
Should be a fun little project!
