Brett, on this note another tack you could take is to symmetrically encrypt
your list with GPG/PGP, being wary of where you choose to decrypt it. This
kind of thing, using gpg (where the path could be a removable device or
floppy):

opiekey -n 5 0499 xx9909 | sort -rn | ( sleep 10 ; gpg -ca -o /trusted/path )

... adding your preferred  --cipher-algo option as required, then as needed run:

gpg -o - /trusted/path | grep #seq_no

cheers,
