Using the shutdown command

To stop the system with the shutdown(1M) command:

1. Log in as root.

2. Enter:

      shutdown -gn
   

   where n is the number of minutes before the shutdown is to take place.

   To go from normal operation to system maintenance mode, use this variation:

      shutdown -gn is
   

   The system displays a broadcast message at each terminal, prompting users to finish their work and log out.

   For instructions on customizing the broadcast message see shutdown(1M).

   Once all users are logged out or the specified time has elapsed, the system closes all accounts and displays this message:

      The system has halted and may be powered off
   

3. If you specified single-user mode on the command line, the system proceeds directly to the single-user prompt without rebooting.

4. If you did not specify single-user mode, turn off the computer or press any key to reboot the system.
