Ping and repeat ?
How do i write a loop ping to see if it get timeout or hang ? it should loop every 30 second to ping a server ?
Code:
ping -c 5 -t 15 www.google.com
if [[ $? != 0 ]]; then
    date '+%Y-%m-%d %H:%M:%S Connection Unavailable' >> /home/sabercats/checkconnection.log
else
    date '+%Y-%m-%d %H:%M:%S Connection Available' /home/sabercats/checkconnection.log
sleep 30
repeat

@sabercats
The syntax and behaviour of the "ping" command varies. Please post what exact Operating System and version you are running and what Shell you use.

@spacebar
Please stop posting on this thread. Your post (now removed) because it does not mention ping .

I guess that what you are asking for is an "endless loop":

Code:
while true do
     ping -c 5 -t 15 www.google.com
     if [[ $? != 0 ]]; then
          date '+%Y-%m-%d %H:%M:%S Connection Unavailable' >> home/sabercats/checkconnection.log
     else
          date '+%Y-%m-%d %H:%M:%S Connection Available' /home/sabercats/checkconnection.log
     sleep 30
done

Any such "endless loop" code needs a controlled exit path. Convention is to test for a "stop" file.
