synopsis
/usr/sbin/shutdown [ -y ] [ -g grace-period ]
[ -i init-state ] [ message ]
description
shutdown is executed by the super-user to change the state
of the machine. in most cases, it is used to change from
the multi-user state (state 2) to another state.
shutdown 被super-user(超级用户)用来转换机器(系统)的状态.通常,
是从多用户状态(state 2 状态2)转换到其他状态.
by default, shutdown brings the system to a state where only
the console has access to the operating system. this state
is called single-user.
shutdown在缺省时执行的结果是把系统转换成只能在控制台上登陆的模式.
这种模式叫单用户模式.
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 standard warning message "the sys-
tem will be shut down in ..." if the string contains more
than one word, it should be contained within single (') or
double (") quotation marks.
在关毕守护程序并且杀掉进程前,shutdown会发出警告给用户,缺省情况下,
会有一个请求最后确认的询问.message是一个打印到标准输出上的警告信息:
"the system will be shut down in ..."如果这个string包含多个
单词,必须用单引号(')或双引号(")引用.
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. see exam-
ples.
警告信息以7200,3600,1800,1200,600,300,120,60,30秒为单位进行输出
到标准输出上.(参看后边的例子)
system state definitions are:
下面是系统状态的定义:
state 0 stop the operating system.
终止操作系统.
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) ser-
vices are unavailable. note that not all
user processes are stopped when transitioning
from multi-user state to state 1.
state 1状态被认为是管理状态.在state 1状态下多用户文件系统
会被安装,并且那些需要多拥护文件系统的登陆方式能够使用.
当系统从(firmware mode)硬件模式进入到state 1时,
只有控制台能够被使用,其他的多用户的服务将不能使用.
请注意从多用户状态(state 2)转换到state 1时,并不是所有的用户
进程都被杀掉.
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 sys-
tem can only be accessed through the console.
logins requiring access to multi-user file
systems cannot be used.
state s(or s)是所谓的单用户模式.当进入这种模式的时候
所有的用户的进程都将被杀掉.在单用户模式下,多用户文件系统
将不被安装.系统只能在控制台上被使用.多用户系统的登陆方式将
不可用.

maintenance commands shutdown(1m)
系统维护命令 shutdown(1m)
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.
关毕机器,以便把电源关掉.rc0进程将被调用执行
这个任务.
state 6 stop the operating system and reboot to the
state defined by the initdefault entry in
/etc/inittab. the rc6 procedure is called to
perform this task.
停止操作系统并且把系统重新起动到缺省的状态如
/etc/inittab里定义的那样.rc6将被调用来执行这项任务.
options
-y pre-answer the confirmation question so the
command can be run without user intervention.
用来对确认信息进行不敏感确认.(对所有确认都回答yes)
-g grace-period
allow the super-user to change the number of
seconds from the 60-second default.
以60秒为单位指定警告信息发送的间隔.
-i init-state if there are warnings, init-state specifies
the state init is to be in. by default, sys-
tem state >qspq is used.
指定转换到的状态.如果有警告信息,将要转换的状态将被加
到警告信息中去.缺省情况下,>qspq将被执行.
examples
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.
下面的例子的目的是:主机将在120秒内被关毕.在最后确认之前,
警告信息每隔2分钟,1分钟30秒被输出到标准输出上..
example# shutdown -i s -g 120 "===== disk replacement ====="
