how to shutdown after 5 min?

[reinerm]

I want to showdown the system, but first warn all currently login users and delay for about 5 min and do the shutdown. I've tried

shutdown -r -t 300

but it only shows me the options on how to use the shutdown command.Any help?


thanks!

try

shutdown -h +5

[reinerm]

thanks it work! but what happened with this?

shutdown -r -t 300

is it wrong?

[btberch]

shutdown -r -t 300

-r is to reboot
-h is to halt the system
for time you: +minutes, now or you can hh:mm for a time

you could also put a message at the end

shutdown -h +5 System back up in an hour.

Hope this helps

just want to clarify..
whats the difference between:

+5 and -t 300

I thought they do the same thing, send some warning message,delay, then do the shutdown. Am I correct?

I have not saw -t used with shutdown, but that doesn't mean you can't, i just haven't saw it. and i have only saw time with + minutes not seconds.

maybe someone smarter than me can answer those questions.
