This is the code fragment I use to check ping. Wrapper it with a while
`true` and a sleep 60.
ping "$i" 2 > /dev/null 2>&1
if [ $? -ne 0 ]; then
echo "host \"$i\" not answering ping...aborting"

Long time reader, first time asker here!
Just wondering if someone could help with a "simple" script in $bash
i have to make.
I need a script that´s pings a certain ip, reads the reply and ... if
there is any reply, it reschedules itself to ping the ip again in
lets say 60 secs.
Otherwise it starts a daemon, firewall, backup smb daemon, etc. .
My doubt is on how to get the script to read the ping awnser
(afirmative or not).
The main interest in this is that if the primary firewall fails (UPS
probs i´m having and lack of $$ to other one ;) ) the backup one goes
Sorry for the lamme question and thanks in advance for your opinions
on how can i do it.
