Cron Script reqeust

I have changed my url. Now i want to setup the new cron. How can i request the new cron job like in step 6 by the installation ? I looked in hosting tools but couldn`t find a way to access it directly.

Upload the attached 'path.php' to your dolphin root folder and view it - http://mydolphinURL/path.php
It will echo the correct path to put into your cron job.

File contents (displayed for security reasons):

<?php
echo ($_SERVER["DOCUMENT_ROOT"])."/periodic";
?>

Cron line (path reflects my own install, change it to the path the above page displays):

MAILTO=admin@your.site
* * * * * cd /var/www/html/dol/periodic; /usr/bin/php -q cron.php
