Help with Crontab

[SergioM]

I just started working with shell scripts & crontab. A tutorial for shell scripts was very useful. Another fro Cron jobs seems equally simple & straight forward, but I must be missing something obvious.

Basically, my crontab looks like this. I want the computer to reboot at 3:35 PM daily. However, when the time comes, it doesn't actually reboot. Or do anything else. When I set it to a path of a shell (IE /etc/cron.d/shutdown.sh) it also does not do anything.

# m h dom mon dow   command
35 15 * * * sudo shutdown -r 0

Can someone tell me what I missed?

I just saw the e-mail that is sent to /var/mail/zoneminder. It says

[sudo] password for zoneminder:

I guess in the case of rebooting the server, I need to create a shell script & pass it the password on the next line? It seems a little unsafe!

To run a root level crontab you must edit the root users crontab

run

sudo crontab -e

and add your command in there

# m h dom mon dow   command
35 15 * * * shutdown -r 0

You may need to add

PATH=/usr/sbin:/usr/bin:/sbin:/bin

as the first line in the crontab file.
