How to run cronjob?
Please use this example command to run cronjob:
php -f /home/YOUR_CPANEL_USERNAME/public_html/file.php
Please note that if you run very heavy cronjobs, your account may be suspended for server overload, so please make sure your cronjobs do not make any heavy queries.
If you are not sure how to setup cronjob to be launched at desired time intervals, please refer to Google or cPanel documentation for more details.
