Help with Crontabs?

[GTaudiophile]

How often does this crontab run?

00 * * * * sudo sh /root/dyndns_update.sh

Every hour on the hour.

How do I change it to run every like 5 minutes?

*/5 * * * * sudo sh /root/dyndns_update.sh

I think that's right

LoKe almost had it but I'm pretty sure you need the */5 and not just /5

Why are you running this in Cron? IIRC they have a daemon that runs in the background and you can set the update frequency in the .conf file.

*/5 * * * * sudo sh /root/dyndns_update.sh

EDIT : Forgot an asterisk.

Why does that command have to be so incredibly cryptic?

It's not, really. All programming languages looking confusing until you learn them.

Sorry, my mistake. I forgot an asterisk.
