Err read the man page? -Pn assumes the host is up (skips the initial ping in case
something drops that when you are interested in a port) so it will say the host is up in
that case - but we don't care about the host being up... we want the service so you
need to parse the service output.
My point being, grepping for "Host is up" doesn't fill the bill. You're
saying what I said....just differently.
I still prefer tcping since there is no need to grep or awk anything. Or worry about text
being changed in a later release. Just rely on exit status.
Don't be bullied by the judgmental grammar and spelling police.
