The CHECKSUM file has both the name of the iso and its expected checksum in it. So the command: $ sha256sum -c Fedora-11-i386-CHECKSUM Causes it to look fat the iso in whose name is in the checksum file, generate a checksum for it and compare that generated checksum against the expected one that is held in the CHECKSUM file.
