Cron Jobs with Lynx

[Wildheart]

Lokking for how to setup a cron job every 12 hours with lynx. I want it to access a php script on the server then null the output. if anyone could show me how to do this please explain the logic behind it so I can learn how it works.

Thanks

ok, as the user:

# crontab -e

(that opens your crontab for editing)

then...


* * * * * lynx http://urlyouwanttocall.com/script.php -O /dev/null

The first * is minutes, the second is hours, then day, month year.

Most hourly crons will look something like:

59 * * * * command

That will run the cron at 59 minutes every hour.

You can also do:
*/3 or */2, or */5, etc... to run it every so many minutes.

so if i do 2 entries staRTING WITH * 1 * * * and
* 12 * * *

I could run one once a day at 1 and another once a day at 12??

It would run at 1am and then noon.

Cron works in 24 hr time.

Dear Wildheart,
Hello,

You should take a look at manuals and page info.

# man 5 crontab
# pinfo crontab
