Refresh a URL from shell script

I have a php page which i run in a browser, it has a the refresh meta tag which refreshes the page after every 15 mins. Now i am running this on a browser. It will refresh and do something and update the database every 15 mins.

So now is there any way i can simulate this using a simple shell script which will hit and refresh this page after a given interval say 15 mins.

I have tried using wget and curl,
with wget i am able to get the response and also download the page but it does not "hit" the php page on the server such that it gets executed and does the jobs like udating database.

Is there any way

Hi
try crontab

Hi venikathir

Crontab part is fine, where in i can schedule the job, the question is "HOW TO" auto refresh a page using a shell script, is there any way, once i get an answer to it, i can configure it in cron.

thanks
