Incorrect. The sha256sum program can automatically check these for
you. That's what the -c option does. There are two basic modes of
operation for sha256sum. When run without the -c option, the program
calculates the sha256 hash of a given file or files and prints those
hashes. When run with the -c (or --check) option, the program will
read the contents of a file (which is the output of a previous
sha256sum) and check whether the hashes listed in the check sum file
match the files that are specified in that check sum file.
Take a look at the sha256sum man page for details (man sha256sum).

I interpret the above as ... sha256sum Fedora-xxx-xxx-CHecksum and the program looks for the iso and calculates the number and checks them with the checksum file for a match or no match? No? If so, this
doesn't work. It is the same answer as Steve Searle's and Doc Savage's.
I think more detail is needed.
