Maintenance Commands shutdown(1M)
系統維護命令 shutdown(1M)
NAME
名稱
shutdown - shut down system, change system state
shutdown - 關畢系統,轉換相同的狀態
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(超級用戶)用來轉換機器(系統)的狀態.通常,
是從多用戶狀態(state 2 狀態2)轉換到其他狀態.
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在缺省時執行的結果是把系統轉換成只能在控制臺上登陸的模式.
這種模式叫單用戶模式.
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.
在關畢守護程序并且殺掉進程前,shutdown會發出警告給用戶,缺省情況下,
會有一個請求最后確認的詢問.message是一個打印到標準輸出上的警告信息:
"The system will be shut down in ..."如果這個string包含多個
單詞,必須用單引號(')或雙引號(")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秒為單位進行輸出
到標準輸出上.(參看后邊的例子)
System state definitions are:
下面是系統狀態的定義:
state 0 Stop the operating system.
終止操作系統.
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狀態被認為是管理狀態.在State 1狀態下多用戶文件系統
會被安裝,并且那些需要多擁護文件系統的登陸方式能夠使用.
當系統從(firmware mode)硬件模式進入到state 1時,
只有控制臺能夠被使用,其他的多用戶的服務將不能使用.
請注意從多用戶狀態(state 2)轉換到state 1時,并不是所有的用戶
進程都被殺掉.
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)是所謂的單用戶模式.當進入這種模式的時候
所有的用戶的進程都將被殺掉.在單用戶模式下,多用戶文件系統
將不被安裝.系統只能在控制臺上被使用.多用戶系統的登陸方式將
不可用.

Maintenance Commands shutdown(1M)
系統維護命令 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.
關畢機器,以便把電源關掉.rc0進程將被調用執行
這個任務.
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.
停止操作系統并且把系統重新起動到缺省的狀態如
/etc/inittab里定義的那樣.rc6將被調用來執行這項任務.
OPTIONS
-y Pre-answer the confirmation question so the
command can be run without user intervention.
用來對確認信息進行不敏感確認.(對所有確認都回答yes)
-g grace-period
Allow the super-user to change the number of
seconds from the 60-second default.
以60秒為單位指定警告信息發送的間隔.
-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.
指定轉換到的狀態.如果有警告信息,將要轉換的狀態將被加
到警告信息中去.缺省情況下,>qspq將被執行.
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:主機將在120秒內被關畢.在最后確認之前,
警告信息每隔2分鐘,1分鐘30秒被輸出到標準輸出上..
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...

Thanks, but can you do me a favor to give
a full explanation on those switches?
