See File::Monitor::Delta. The module is able to monitor changes to file size.

A file can change in many ways. What exactly would you consider a file "change"? Perhaps checking the file's modified time mtime is sufficient enough for your needs?

If you're interested in whether the contents of the file changed, you may want to look at Digest::file.
