Automatic mail sending

[eluser]Roy MJ[/eluser]
Hey,
Ive tried doing the cron job. But i cant find a way as to how the command will be like so that i can add a cron job via cpanel.

* * * * * /usr/local/bin/php -q /home/public_html/system/application/controller/cron.php

But i dont see it working. My cron.php looks like this :

Code:

<?php
class Cron extends My_Controller {
    function cleancache(){
        parent::My_Controller();
        $this->load->model('admin/News_subscribe_model');
        * * * * * /usr/local/bin/php5 $HOME/system/scripts/clean_cache.php
        if($_SERVER['SCRIPT_FILENAME'] != 'clean_cache.php')
          exit;
        
    }
    function index(){
              
                    $to = "[email protected]";
                    $fromemail = $this->config->item('admin_email');
                    $subject = "hi";
                    $message = "heloooooooo";
                    $fromname = "Aroma";
                    mail($to, $subject, $message, "From: $fromname<$fromemail>" );
        }
      
}

?&gt;

Can u please find what im doing wrong here. In cpanel i gave this command as cron job..

Code:

$HOME/system/application/controller/cron.php
