g'day all,
a mate is maving a problem with the following, and i tried the
behaviour under zsh and it doesn't work either. is there a
reason why this doesn't work? and what would be a good
solution? (i suggested setopt multios; prog x y z > /dev/stdout
> filename)
thanks zsh gurus!

Subject: [slug-chat] Script challenge with tee
Envelope-to: andrep@localhost
X-Mailer: Endymion MailMan Standard Edition v3.0.26
I have a problem, I want to tee and still get the return code:
prog x y z | tee
echo $?
Will always show zero because this is the return code of tee. I need the
return value of prog.
{
prog x y z
echo $?
} | tee
works but I want to capture the values so that I can exit much later with the
value of this program.
{
prog x y z
RC=$?
} | tee
lp ...
exit $RC
RC is does not appear to be available to the script.
Any suggestions?
