Shutting down linux at a specific time.

[donaldfarkas]

So at work I usually forget to shut down my computer at the end of the day 5:30 and they switch the breaker off at 6pm which cant be good way to shut down a computer. So i was doing some googling and this is what i come up with.

this is the example i found online

#crontab -e -u root

0 20 * * * /sbin/shutdown -h now

since the above turns it down at 8pm i need to edit it to 5 30pm

0 17:30 * * * /sbin/shutdown -h now

would this be correct?

My method is quite primitive. Hope you get to know of a more efficient way

su -
shutdown -h 120

120 minutes and its off...
