Yeah, but they will exit with an error. I think that's what Raphael
wanted to avoid. But you have a point, since:
can be used for that.
Brendan Taylor suggested that "|| true", AFAICF (could find ;).

I don't think it would, because of that ^. But it would, if there is

grep '^lfs:' /etc/passwd
would work (where lfs should be &lfs-user; in general).
