          use the following command,



          Example:



          watch -n 10 tail /var/log/LogFileName



          watch -n 10 tail /var/log/auth.log



          We can view the logs for every 10secs of a growing log file.

          • Otherwise, what error do you get, and have you tried "man watch" to get information on the command?
