In response to JWP's episode 2697 and ClaudioM's comment, this show covers the
shutdown command as it appeared in Sun Solaris and OpenSolaris, and currently appears in both Oracle Solaris and OpenIndiana.
The quick version:
-i sets the destination init state (5 to shutdown, 6 to reboot, and so on; see
man init for more)
-y to answer "yes" to the safeguard prompt asking you whether you really want to shutdown
-g to set how many seconds until shutdown. Default is 60.
In practise, I don't even use the shutdown command. I use
poweroff, which does a shutdown and poweroff.
Both shutdown and poweroff require root permission. On OpenIndiana, you can either use
sudo bash or
pfexec bash to get a root prompt.

Quite a Different Shutdown
A very informative episode. I hadn't realized how different the shutdown command functions on illumos-based operating systems is from the BSDs and Linux. You've also inspired me to make an HPR episode on a similar command with the same name in another OS I have to use from time to time.
