Here's what I do on the command line (I'm certain there may be better methods
which may make more sense if you verifying many files):
echo <known good checksum cut/pasted from website/whatever>
md5sum <downloaded file>
then do a visual comparison of the two strings. For example, if I know the
checksum for foo.iso should be "d41d8cd98f00b204e9800998ecf8427e":

Having the known good and the calculated checksum on top of each other makes
comparison easier.
