cron help

[Jiraiya]

i need help on how to create a cron i have looked for tutorials but dont really get it. i want to create a cron that updates a varable in my table every hour

A cron job can do very little on it's own.  It's just capable of firing off an executable with arguments, so the cron wouldn't actually update a value on a table; it would fire off a script or something that would.

 

 

 

 

cron is the program, and it reads cron tabs.  So really, you don't want to create a cron; you want to create a crontab entry.

If you wanted the PHP script /SomeScript.php to run the 33rd minute of every hour, you would add the following line to the crontab file:

 

33 * * * * php /SomeScript.php

 

 

 

Oh, you might want to pipe it to null, by the way:

 

33 * * * * php /SomeScript.php > /dev/null 2>&1
