Hello
im using sunos and i need to somehow ping other sun in the network but
geting boolean return and not the "sun is alive" response can it be done ?

I think this had been answered already ! ( Not sure, though )

Now you have the required value in $?

its giving me the msg
Ambiguous output redirect

Could you please post the command that you had executed? ( If possible )

We could have a look !!!

ping sun8 2>/dev/null 1>&2

output
Ambiguous output redirect.

can i somhow to prevent the output of
ping: unknown host sun?
when the ping failed?

Thanks

It complains about the output redirect, which is strange cause it is correct as defined. However you can try changing the redirect.

Instead of:
ping sun8 2>/dev/null 1>&2
try:
ping sun8 >/dev/null 2>&1

if that doesn't work you can try:
ping sun8 > /dev/null 2>/dev/null
