This little script should works perfect and could be a perfect solution to me.
However, owing to the BUG in 'who' (which lists users who have already
logoff'ed and so in the list there are entries with same tty number), it
fails consistently. :-(

Is this bug fixed in 3003? We've just got the update tape and have not
applied it yet.

Thanks for the solution.
