Cron question - run script at fixed times throught the day?

AARRRGH

Hello

I have a PHP script I would like to run at 9am 12pm 3pm 6pm and 9pm.

Is there anyway I can define cron to do this?

Currently I have it running every three hours, but I would prefer to specify the exact times to run the script.

Any help appreciated.

Thanks

0 9,12,15,18,21 * * * yourcurrentcommand

would this not do it for you ?

Ideally this wouldn't be a publically accessible URL as I assume it'll be slightly intensive and you're leaving yourself open to attacks on you system if it becomes common knowledge ... Also ... it won't work as you're trying to load a php file which has already been processed by the server

As he already had it running every 3 hours I left it as yourcurrentcommand

How about something like this:

Crontab:
17 16 * * 0 yourShell.sh > yourlog.log 2>&1

where yourShell.sh contains:

echo "get /yourPage.php" | telnet yourwebserver 80

If required, you could try checking that the remote ip address is the one from which the cronjob is running.

I have a cronjob that uses wget to access a password protected page (just basic htaccess protection):

0 9,12,15,18,21 * * * wget --http-user=TheUser --http-passwd=ThePasswd http://www.yoursite.com/yourpage.php

OP - tell us more about what the script does and the current access method.

Hello

Thanks for all the replies.

I reckon this will do it -

0 9,12,15,18,21 * * * php -f /home/whatever/yourcurrentcommand.php

Thanks again everyone!
