   I'm not sure, but it's easy enough to script.  See below the signature.
   If you don't have /bin/ksh, change the first line to #!/bin/sh.

   You definitely need either the Linux compatibility stuff or a decent
   version of ncurses installed for this to work.  The basic version of
   tput (/usr/bin/tput) will not do the trick.

   Agreed.  That's why I always install the GNU coreutils package, which
   includes the "md5sum" program.
