Cronjob Help

[WebWatcher]

Can somebody show me how I could set up a cronjob to run a particular script every friday night at 7pm

Thanks in advance

How would you make a cron run script.php every 0.1 seconds?

 

[krakjoe]

you wouldn't ...

<?php
/** delcare a function to execute **/
/** in your case **/
/** probably include() a file **/
function lengthy_process( )
{
	for( $i = 0; $i < 10000; $i++ )
	{
		continue ;
	}
}
/** continue forever **/
do
{
	/** execute operation **/
	lengthy_process( );
	/** sleep for 0.1 seconds inbetween ending of **/
	/** execution and beginning the next **/
	usleep( 100000 );
}
while( true );
?>

nohup nice php script.php &

will execute forever untill you kill with

kill procid

you can discover procid by

ps aux | grep script.php

assumes code is named script.php ...

If you don't have that level of access, the best you can do is every minute, of every hour, of every week, of every month ...
