How do I get a script to run every say half hour on any system. I want it to run and check to see if something has been updated. How do I get it to do that?
On unix you use cron
man crontab man 5 crontab
crontab -e (warning: the above may drop you into the vi editor. It's not easy to exit out. Look for a vi basic commands tutorial first.)
I'm sure a task scheduler of some sort exists for win32.
also if you don't have a cgi version and want to run the script on the web, you would use
lynx -dump http://someserver.com/my-script.php
to force the php script on the server to run..
take some precautions to make sure not just anyone can force the script to run..
