Shutdown Command

AL_3001 — Thu, 11 Oct 2007 12:41:30 GMT

Hi Friends,
I have to issue a shutdown command with a message 15 minutes prior to the shutdown.
shutdown -r -y 900 (i am assuming 900 seconds)

Kindly correct if i am wrong?

Thanks.

That is the correct way and yes 990 is seconds...

With the -y - you won't be prompted to give your own message....

Yes, that's correct if you want the machine to shutdown and then reboot. If you just want it to shut down, then use the -h option instead of -r.

This is the kind of question that should never be asked. A simple "man 1m shutdown" would answer your question for a specific OS version and would be more trustworthy than listening to a bunch of people on the Internet. If you have to ask how to do a routine shutdown then you are probably not the person who should be doing it because the grace period is probably the least significant criterion. Of far more import is "Is it safe to shutdown now?" or "Do all of my applications have graceful rc shutdown scripts?".

If you want to document that you are waiting 15 minutes you can use:
# shutdown -r -y $(( 15*60 ))
