I find this solution to run a URL every 5 minutes from cPanel you can execute any task by this command.
*/5 * * * * This on run At every 5th minute. so it only runs once in one hour
Here is an example that i use to run my URL every second
*/5 * * * * curl http://www.example.com/;
sleep 5m; curl http://www.example.com/;
sleep 5m; curl http://www.example.com/;
sleep 5m; curl http://www.example.com/;
sleep 5m; curl http://www.example.com/;
sleep 5m; curl http://www.example.com/;
sleep 5m; curl http://www.example.com/;
sleep 5m; curl http://www.example.com/;
sleep 5m; curl http://www.example.com/;
sleep 5m; curl http://www.example.com/;
sleep 5m; curl http://www.example.com/;
sleep 5m; curl http://www.example.com/;
To sleep for 5 seconds, use:
sleep 5
Want to sleep for 5 minutes, use:
sleep 5m
Halt or sleep for 5 hours, use:
sleep 5h
If you do not want any email of cron job just add this to end of the command
