execute operate in wordpress plugin utilizing crontab

So, I need to run a operate on my plugin from crontab. For the instance, I need to run it day-after-day at 1:10am

operate my_cronjob_action () {
    //this operate is in my plugin
    // code to execute on cron run
    syslog(LOG_DEBUG, 'executed by unix cron');
} add_action('my_cronjob_action', 'my_cronjob_action');

I’ve disabled wp-cron by including outline( 'DISABLE_WP_CRON', true ); into wp-config.php
what is the subsequent step so the operate could be executed from crontab?

Thanks earlier than.
