Hi all,
thanks a lot for the overwhelming feedback to my question. I got about
30 answers in 5 minutes. I am still browsing through all the replies.
Most of you suggested to do something like
#!/bin/bash
ping snap >/dev/null
if [ $? != 0 ]; then
echo snap is down! Do something about it...
else
echo snap is already on!
fi
which worked great for me.
Thanks again!
Regards,
Andreas

Original question:
this is a question for shell script gurus. I need a script called by
cron that performs a specific action (call another script) if host snap
is down. I thought about checking this with
bash-2.03# ping snap
no answer from snap
If snap is down the answer "no answer from snap" is returned. But how
can I use this in a shell or expect script to call my action script? If
the answer "snap is alive" is returned I want to do nothing. I guess
this can easily be done but I am unfortunately not such a script expert
yet.
