Verify an iso image
The simple way:
sha1sum Fedora-7-Live-i686.iso
If an sha1sum file was delivered with the iso image, you can use this command.
sha1sum -c SHA1SUM
The -c tells the program to read files out of the SHA1SUM text file and generate sha1sums on all of those files. Then, it compares the generated value to the value in the text file and tells you if it matches.
Verify a CD
Use this after you have burn the iso image to the CD.
sha1sum /dev/hdc
The source that I found says to use the actual device rather than a link (instead of /dev/cdrom).
