hide stdout but need exit status
Hi:

Code:
echo "Escriba el nombre de usuario: \c"
read user

lsuser -a $user 2>/dev/null || (echo "Usuario no valido en el sistema. Abortando." &&  exit 1)

I want:
- If 'lsuser -a $user' fails, script exits but hide stderr.
- If 'lsuser -a $user' succeeds, script continue, and hide stdout.

thx in advance
Israel.

1>/dev/null at the end of your statement which outputs to the screen.

but if I use 1>/dev/nulll when 'lsuser -a $user' fails I see stderr on screen...I want to hide stderr or stdout on both ways (fails or succeeds)

regards
Israel.

Maybe
Code:
lsuser -a $user >/dev/null 2>&1 || (echo "Usuario no valido en el sistema. Abortando." && exit 1)

umm.. there is something odd here... I realized the problem is in (echo "Usuario no valido en el sistema. Abortando." && exit 1) string... if I use:

lsuser -a $user >/dev/null 2>&1 || exit 1 it works

do you know why?
I'm using ksh93 on AIX.

thanks again
