- This command brings the system to a state where nothing is running so the
- power can be turned off.
-
- By default, the user is asked questions that control how much warning the
- other users are given. The options:
-
- ----yyyy prevents the questions from being asked and just gives the warning
- messages. There is a 60 second pause between the warning messages.
-
- ----YYYY is the same as ----yyyy except it has no pause between messages. It is
- the fastest way to bring the system down.
