Shell script for cron url

Hi guys,

I have a serious issue with running cron command. My host not supported format below mentioned, just the URL.) http://www.mysite/example.php ( I�m affraid a bit, the host do not going to support the sh as well�anyway)

Somehow I need to �wrap� this command, to able to call cron:

php "/web/mysite/mysite.com/administrator/components/comex/helpers/cron.php" username="admin" passwd="adminpass" template_id="50"

Could somebody help me out, how can I solve?
Thanks in advance
