The following procedures and examples describe how to shut down a system by using the shutdown and init commands.
For information about shutting down a system for recovery purposes, including using the halt command, see SPARC: How to Stop a System for Recovery Purposes.
For Oracle Solaris systems that are used as multiuser timesharing systems, you might need to determine if any users are logged into the system before shutting it down. Use the following procedure in these instances.
$ who holly console May 7 07:30 kryten pts/0 May 7 07:35 (starlite) lister pts/1 May 7 07:40 (bluemidget)
Data in the first column identifies the user name of the logged-in user.
Data in the second column identifies the terminal line of the logged-in user.
Data in the third column identifies the date and time that the user logged in.
Data in the fourth column, if present, identifies the host name if the user is logged in from a remote system.
# who
A list of all logged-in users is displayed.
# shutdown -iinit-state -ggrace-period -y
Brings the system to an init state that is different from the default of S. The choices are 0, 1, 2, 5, and 6.
Run levels 0 and 5 are states reserved for shutting the system down. Run level 6 reboots the system. Run level 2 is available as a multiuser operating state.
Indicates a time (in seconds) before the system is shut down. The default is 60 seconds.
Continues to shut down the system without intervention. Otherwise, you are prompted to continue the shutdown process after 60 seconds.
For more information, see the shutdown(1M) man page.
Do you want to continue? (y or n): y
If you used the shutdown -y command, you will not be prompted to continue.
Type Ctrl-d to proceed with normal startup, (or give root password for system maintenance): xxxxxx

Example 3-1 Bringing a System to a Single-User State (Run Level S) by Using the shutdown Command
In the following example, the shutdown command is used to bring a system to run level S (the single-user state) in three minutes.
# who root console Apr 15 06:20 # shutdown -g180 -y Shutdown started. Fri Apr 15 06:20:45 MDT 2011 Broadcast Message from root (console) on portia Fri Apr 15 06:20:46...

Example 3-2 Bringing a System to a Shutdown State (Run Level 0) by Using the shutdown Command
In the following example, the shutdown command is used to bring a system to run level 0 in five minutes without requiring additional confirmation.
# who root console Jun 17 12:39... userabc pts/4 Jun 17 12:39 (:0.0) # shutdown -i0 -g300 -y Shutdown started.

Apr 15 06:41:57 The system is down. Shutdown took 69 seconds. syncing file systems... done Press any key to reboot. Resetting...
If you are bringing the system to run level 0 to turn off power to all devices, see Turning Off Power to System Devices.
Example 3-3 Bringing a System to a Multiuser State (Run Level 3) by Using the shutdown Command
In the following example, the shutdown command is used to reboot a system to run level 3 in two minutes. No additional confirmation is required.
# who root console Jun 14 15:49 (:0) userabc pts/4 Jun 14 15:46 (:0.0) # shutdown -i6 -g120 -y Shutdown started.

Regardless of why you shut down a system, you will probably want to return to run level 3, where all file resources are available, and users can log in. For instructions on bringing a system back to a multiuser state, see Chapter 4, Booting a System (Tasks).
Use this procedure when you need to shut down a stand-alone system.
# init 5
For more information, see the init(1M) man page.
Example 3-4 Bringing a System to a Shutdown State (Run Level 0) by Using the init Command
In this example, the init command is used to bring a stand-alone system to the run level where it is safe to turn off power.
# init 0 # INIT: New run level: 0 The system is coming down. Please wait. . . . The system is down. syncing file systems... [11] [10] [3] done Press any key to reboot
