Well, if you're on a Linux computer, and the files you're testing plus the MD5SUM are all the same directory, just do: md5sum -c MD5SUM How can one file do it all? Simply because this one file knows about all the associated iso images. PS: It seems there's precious little information about md5sum in the man pages or HOWTO docs. I know, because I looked this morning. I had a very similar question just a few hours ago.
