NAME
shutdown - shut down system, change system state
SYNOPSIS
/usr/sbin/shutdown [-y] [-g grace-period] [-r | -p | -i init-state]
[message]
DESCRIPTION
shutdown is executed by a system administrator to change the run level
of the machine. In most cases, it is used to change from the multi-user
state to another state.
shutdown must be run with an effective uid of 0, which may be provided
by the Maintenance and Repair rights profile.
By default, shutdown brings the system to a state where only the con‐
sole has access to the operating system. This state is called single-
user.
Before starting to shut down daemons and killing processes, shutdown
sends a warning message and, by default, a final message asking for
confirmation. message is a string that is sent out following the stan‐
dard warning message:
The system will be shut down in ...
If the string contains more than one word, it should be contained
within single (') or double (") quotation marks.
The warning message and the user provided message are output when there
are 7200, 3600, 1800, 1200, 600, 300, 120, 60, and 30 seconds remaining
before shutdown begins. The user provided message (as much as will fit)
is added to the wtmpx record generated by init(8). See EXAMPLES.
System state definitions are:
state 0 Stop the operating system.
state 1 State 1 is referred to as the administrative state. In
state 1 file systems required for multi-user operations
are mounted, and logins requiring access to multi-user
file systems can be used. When the system comes up from
firmware mode into state 1, only the console is active
and other multi-user (state 2) services are unavailable.
Note that not all user processes are stopped when transi‐
tioning from multi-user state to state 1.
state s, S State s (or S) is referred to as the single-user state.
All user processes are stopped on transitions to this
state. In the single-user state, file systems required
for multi-user logins are unmounted and the system can
only be accessed through the console. Logins requiring
access to multi-user file systems cannot be used.
state 5 Shut the machine down so that it is safe to remove the
power. Have the machine remove power, if possible. The
rc0 procedure is called to perform this task.
state 6 Stop the operating system and reboot to the state defined
by the initdefault entry in /etc/inittab. The rc6 proce‐
dure is called to perform this task.
See init(8) for more information on the system run levels corresponding
to these states.
OPTIONS
-y
Pre-answer the confirmation question so the command can be run
without user intervention.
-g grace-period
Specify the number of seconds to wait and warn users before switch‐
ing states. If this option is not used, the default is 60 seconds.
-i init-state
Specify the init-state to change to at the end of the grace period,
as if 'init init-state' was run. By default, system state 's' is
used.
-r
Equivalent to specifying -i6.
-p
Reboots to prom. This flag can be used to reboot the system through
firmware without changing the default reboot behavior as denoted by
the config/fastreboot_default property setting in the system/boot-
config service.
The -p and -i options are mutually exclusive.
EXAMPLES
Example 1 Using shutdown
In the following example, shutdown is being executed on host foo and is
scheduled in 120 seconds. The warning message is output 2 minutes, 1
minute, and 30 seconds before the final confirmation message.
example# shutdown -i S -g 120 "===== disk replacement ====="
Shutdown started. Tue Jun 7 14:51:40 PDT 1994
Broadcast Message from root (pts/1) on foo Tue Jun 7 14:51:41...
The system will be shut down in 2 minutes
===== disk replacement =====
Broadcast Message from root (pts/1) on foo Tue Jun 7 14:52:41...

NOTES
When a system transitions down to run level 1 or single user (run level
S or s), the /etc/nologin file (see nologin(5)) is created. Upon subse‐
quent transition to run level 2, 3, or 4 (multi-user state), the
/etc/nologin file is removed.
When you shut down an image, services are shut down in reverse depen‐
dency order.
Shutdown may be blocked if an admin has used sysadm(8) to place the
system into a noreboot maintenance mode, or if the config/noreboot
property is set to true on the svc:/system/boot-config SMF service.
