So I imagine that you ideally want to run this once to save a set of MD5 checksums and then later you would want to run a similar program to compare the 'saved set' versus the 'new set'?

Well you could create a function that creates a file containing filename,checksum records per line and another function that reads that first file, record by record, and computes the new checksum and does a compare and then outputs your print statement saying that they are different, if they are different.
