use of ping


I would like to use the ping command to test the remote server in every hour

I tried to add a crontab job as below .

* 5-23 * * * ping 192.168.0.1

but it will add a new ping process in every hour , after hours , there are many ping process in the system , can advise if I only want to ping the remote server
( submit one ping packet will do , no need to continuely ping and do not leave ping process in the system ) , can advise what can i do ? thx

You can try the -c option to set the number of ECHO_REQUESTS and the -W option to set timeout, otherwise ping will run indefinitely until it is interrupted by a kill signal. Then maybe you need to store the output somewhere: you can redirect output to a file and check it periodically.
