I imagine the "safest" way (without writing a utility to do this) would be to use FOR to expand the command line argument (e.g., %1.??). Then, for each file, use FIND (OhMiGod) to extract the pertinent line from a master CHECKSUMS file into a temp file. Use CKSUM.EXE to compute a checksum into yet another temporary file and finally COMP to verify they agree. Sheesh! Sounds like it would be easier to just write it all from scratch (bummer!) -- and people have the NERVE to call DOS an O.S.! > I actually had to do a DOS cksum-like clone, years ago, and for > compatibility it was necessary to sort the file args during the > globbing. Unfortunately this is something ports from UNIX frequently > don't take into account. The cksum.c in FBSD pretty much compiles out of the box -- have to drag in getopt() though... I'd like to stick to using cksum as is simply because of all of the grief over the different versions of cksum over the years. It seems like it would also be a good general purpose utility to have in DOSland for those folks that want to manually do a checksum and verify *by hand* against some published cksums... --don
