test [ "`sha1sum cd.iso`" = "`cat checksumfile.txt`" ] && echo "matches" || "echo "no match" where checksumfile.txt is the one provided by the web site.
Minor correction to the above. I booted to my FC partition and tested it outside and within a script. The proper syntax is: test "$(sha1sum cd.iso)" = "$(cat checksumfile.txt)" && echo "Matches" || echo "No match" or test "`sha1sum cd.iso`" = "`cat checksumfile.txt`" && echo "Matches" || echo "No match" The difference being no square brackets []. Of the two syntaxes above, I've been typically using the back ticks ` (above the tidle ~). But in a BASH scripting book that I have the author uses $() instead of ``. If you have several iso files that youve downloaded along with their checksum files, simply cat all the files into one cat cd1chksum.txt cd2chksum.txt cd3chksum.txt etc... > checkthese.txt and then run the command sha1sum -c checkthese.txt A quick and efficient way to check several checksum files.
