	Description:		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: `shutdown` `-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. Some links: OpenIndiana handbook Sun Microsystem docs (with Oracle branding on it)
