In SCO Xenix, the C-shell thinks it really is C: test -s /usr/spool/mail/miller returns 0 (assuming the file is nonempty) so the C-shell doesn't evaluate the second half of the conditional expression. && and || both work exactly the opposite of how one would expect them to work (and of how they do in fact work in the Bourne shell). -- Dave Eisen Home: (415) 323-9757 dkeisen@Gang-of-Four.Stanford.EDU Office: (415) 967-5644 1447 N.
