i there a way to do this?

[mjohn87]

I would like to run a script on my site. I want it to run 24/7 on the server without it having anything to do with ppl lookin on my site. Basically I'm trying to write a script that checks something on a different site and once that thing is there, I want it to e-mail me. Is there anyway this can be done? using php or anything else? thank you in advance.

i am trying to use cron buy it wont work

im using it off my schools netwroks btw, they give each student 125 mb space

heres what i did,i put this in the cron file:
* * * * * /usr/local/bin/php /afs/cad.njit.edu/u/j/m/jmm83/public_html/mail.php
when i use crontab cron in ssh its suppose to run every minute but it doesnt, it never runs not even once

when i just put this command in ssh: /usr/local/bin/php /afs/cad.njit.edu/u/j/m/jmm83/public_html/mail.php
it does run it and i do get the e-mail

it seems my school doesnt allow the use of cron, which is why mine didnt work :\

i would like to somehow run a command or script periodically on the server
