shutdown
The shutdown command is similar to the restart command, but it simply shuts the computer down and does not reboot.
If the optional <delay seconds> parameter is provided, the shutdown will happen automatically after the specified delay.
If a user is logged in, a UI will be displayed that shows the delay counting down. In this case, the UI will have a Shutdown Now button instead of a Cancel button.
If the delay parameter is not specified, the user is prompted to press a button to shut down the computer.
Syntax
shutdown [<delay seconds>]
Where delay seconds is an optional parameter to provide a lag before shutting down.
Example
shutdown 180
This command will shut down the computer in three minutes.
CAUTION
The delayed shutdown is a forced shutdown; it will not prompt the user to save changes to documents, etc. The machine will shut down without further prompting.
