    I'm partial to

            echo $0 | at now + 18 hours

    since it continues to work even if the script gets moved/renamed and I forget
    to change self references inside the script. Data duplication is bad. ;)
    This is assuming the use of a shell that puts the command in $0, obviously.

    It might be a good idea to touch a file (/var/state/scriptname, perhaps)
    to ensure that the script's running periodically, and have a cron job that
    sends a warning email if that file's older than 18 hours or so...
