shutdown -i怎么设置其他时间比如2小时

Windows关机命令~

window cmd命令关机和重启

1、在键盘上同时按“Win+R”打开运行窗口，输入“at 18:00 Shutdown -s”命令，如下图所示：

2、如果解除定时关机，可以再去运行窗口中输入“Shutdown.exe -a”命令，如下图所示：

其它参数，能在Shutdown.exe中按需使用。
-f：强行关闭应用程序
-m \\计算机名：控制远程计算机
-i：显示图形用户界面，但必须是Shutdown的第一个选项
-l：注销当前用户
-r：关机并重新启动
-t 时间：设置关机倒计时
-c "消息内容"：输入关机对话框中的消息内容（不能超127个字符）
扩展资料：
注意要点
shutdown-a 如在设置原shutdown时间参数差值太小则有可能来不及操作就已经被执行。
举例如下：
shutdown -s -t 1 （在1秒内关闭计算机）（一般的时候连关机提示框都是一闪而过。）
当这条命令运行时，直到用户输入并执行shutdown -a来取消操作，中间的时间差只有一秒，很明显是不太可能实现的.遗憾的是在Windows中没有类似LINUX下的CTRL+BREAK来强行终止命令的执行。（Ctrl+C似乎可以……）

shutdown -r +2 表示2分钟后重新启动

shutdown 命令可以安全关闭或者重新启动系统。shutdown命令不仅可以关闭系统、也可以重启Linux系统。

命令语法：

/sbin/shutdown [-t sec] [-arkhncfFHP] time [warning-message]
命令参数：

参数

长参数

描叙

-a

Use /etc/shutdown.allow.

-c

中断关机：当执行"shutdown -h 12:00"指令时，只要按+键就可以中断关机的指令

-f

重新启动时不进行磁盘检测（fsck）

-F

重新启动时进行磁盘检测（fsck）

-h

关闭电源

-k

模拟关机（不是真的关机），只是向登录者发送警告信息出去！

-n

不调用init进程进行关机，而是强行关机

-r

关闭系统然后重新启动，类似于Windows平台restart

-t

延迟关机的时间

-w

仅做测试，并不真的将系统重新开机，只会把重开机的数据写入/var/log目录下的wtmp记录文件

SHUTDOWN(8) Linux System Administrator钬檚 Manual SHUTDOWN(8)

NAME
shutdown - bring the system down

SYNOPSIS
/sbin/shutdown [-t sec] [-arkhncfFHP] time [warning-message]

DESCRIPTION
shutdown brings the system down in a secure way. All logged-in users are notified that the system is going
down, and login(1) is blocked. It is possible to shut the system down immediately or after a specified delay.
All processes are first notified that the system is going down by the signal SIGTERM. This gives programs like
vi(1) the time to save the file being edited, mail and news processing programs a chance to exit cleanly, etc.
shutdown does its job by signalling the init process, asking it to change the runlevel. Runlevel 0 is used to
halt the system, runlevel 6 is used to reboot the system, and runlevel 1 is used to put to system into a state
where administrative tasks can be performed; this is the default if neither the -h or -r flag is given to shut-
down. To see which actions are taken on halt or reboot see the appropriate entries for these runlevels in the
file /etc/inittab.

OPTIONS
-a Use /etc/shutdown.allow.

-t sec Tell init(8) to wait sec seconds between sending processes the warning and the kill signal, before
changing to another runlevel.

-k Don钬檛 really shutdown; only send the warning messages to everybody.

-r Reboot after shutdown.

-h Halt or poweroff after shutdown.

-H Halt action is to halt or drop into boot monitor on systems that support it.

-P Halt action is to turn off the power.

-n [DEPRECATED] Don钬檛 call init(8) to do the shutdown but do it ourself. The use of this option is dis-
couraged, and its results are not always what you钬檇 expect.

-f Skip fsck on reboot.

-F Force fsck on reboot.

-c Cancel an already running shutdown. With this option it is of course not possible to give the time argu-
ment, but you can enter a explanatory message on the command line that will be sent to all users.

time When to shutdown.

warning-message
Message to send to all users.

The time argument can have different formats. First, it can be an absolute time in the format hh:mm, in which
hh is the hour (1 or 2 digits) and mm is the minute of the hour (in two digits). Second, it can be in the for-
mat +m, in which m is the number of minutes to wait. The word now is an alias for +0.

If shutdown is called with a delay, it creates the advisory file /etc/nologin which causes programs such as
login(1) to not allow new user logins. Shutdown removes this file if it is stopped before it can signal init
(i.e. it is cancelled or something goes wrong). It also removes it before calling init to change the runlevel.

The -f flag means 钬榬eboot fast钬? This only creates an advisory file /fastboot which can be tested by the sys-
tem when it comes up again. The boot rc file can test if this file is present, and decide not to run fsck(1)
since the system has been shut down in the proper way. After that, the boot process should remove /fastboot.

The -F flag means 钬榝orce fsck钬? This only creates an advisory file /forcefsck which can be tested by the sys-
tem when it comes up again. The boot rc file can test if this file is present, and decide to run fsck(1) with
a special 钬榝orce钬?flag so that even properly unmounted filesystems get checked. After that, the boot process
should remove /forcefsck.

The -n flag causes shutdown not to call init, but to kill all running processes itself. shutdown will then
turn off quota, accounting, and swapping and unmount all filesystems.

ACCESS CONTROL
shutdown can be called from init(8) when the magic keys CTRL-ALT-DEL are pressed, by creating an appropriate
entry in /etc/inittab. This means that everyone who has physical access to the console keyboard can shut the
system down. To prevent this, shutdown can check to see if an authorized user is logged in on one of the vir-
tual consoles. If shutdown is called with the -a argument (add this to the invocation of shutdown in /etc/init-
tab), it checks to see if the file /etc/shutdown.allow is present. It then compares the login names in that
file with the list of people that are logged in on a virtual console (from /var/run/utmp). Only if one of those
authorized users or root is logged in, it will proceed. Otherwise it will write the message

shutdown: no authorized users logged in

to the (physical) system console. The format of /etc/shutdown.allow is one user name per line. Empty lines and
comment lines (prefixed by a #) are allowed. Currently there is a limit of 32 users in this file.

Note that if /etc/shutdown.allow is not present, the -a argument is ignored.

HALT OR POWEROFF
The -H option just sets the init environment variable INIT_HALT to HALT, and the -P option just sets that vari-
able to POWEROFF. The shutdown script that calls halt(8) as the last thing in the shutdown sequence should
check these environment variables and call halt(8) with the right options for these options to actually have
any effect. Debian 3.1 (sarge) supports this.

FILES
/fastboot
/etc/inittab
/etc/init.d/halt
/etc/init.d/reboot
/etc/shutdown.allow

NOTES
A lot of users forget to give the time argument and are then puzzled by the error message shutdown produces.
The time argument is mandatory; in 90 percent of all cases this argument will be the word now.

Init can only capture CTRL-ALT-DEL and start shutdown in console mode. If the system is running the X window
System, the X server processes all key strokes. Some X11 environments make it possible to capture CTRL-ALT-DEL,
but what exactly is done with that event depends on that environment.

Shutdown wasn钬檛 designed to be run setuid. /etc/shutdown.allow is not used to find out who is executing shut-
down, it ONLY checks who is currently logged in on (one of the) console(s).

2：马上关闭Linux系统，其中 now 相当于时间为 0 的状态
[root@db-server ~]# shutdown -h now

Broadcast message from root (pts/1) (Sat Jan 10 18:51:34 2015):

The system is going down for system halt NOW!

3：系统2分钟后重新启动，其中+m表示几分钟后关机或开机。

[root@db-server ~]# shutdown -r +2

Broadcast message from root (pts/2) (Sat Jan 10 19:56:00 2015):

The system is going DOWN for reboot in 2 minutes!

4：设置系统在那个时间点关机

[root@db-server ~]# shutdown -h 12:30

或

[root@db-server ~]# shutdown -h 12:30 &
[1] 4578

最好是使用命令&将关机命令至于后台处理。不影响当前其它操作。
设置多久时间后执行shutdown命令。时间参数有hh：mm或+m两种模式。hh：mm格式表示在几点几分执行shutdown命令。例如 “shutdown 10：45”表示将在10：45执行shutdown.+m表示m分钟后执行shutdown.比较特别的用法是以now表示立即执行shutdown. 值得注意的是这部分参数不能省略。另外，需要注意如果现在已经22:30，你执行了shutdown -h 22:00 & 那么第二天才会关机。

5：将前一个shutdown命令取消息

如下所示，执行了下面命令让Linux在12:30关机，但是如果发现这个时间点不合适，那么可以使用CTRL+C取消
[root@db-server ~]# shutdown -h 12:30

Shutdown cancelled.
[root@db-server ~]#
也可以在另外一个命令窗口执行下面命令
[root@db-server ~]# shutdown -c

6：向所有登录的用户发出信息
[root@db-server ~]# shutdown -k "now"

Broadcast message from root (pts/2) (Sat Jan 10 20:09:14 2015):

The system is going down to maintenance mode NOW!

Shutdown cancelled.

另外登录的会话窗口会收到如下信息
[root@db-server ~]#
[root@db-server ~]#
Broadcast message from root (pts/2) (Sat Jan 10 20:11:34 2015):

The system is going down to maintenance mode NOW!

一般使用下面语法，如下所示

[root@db-server ~]# shutdown -k now "The Server will shutdown now"

Broadcast message from root (pts/1) (Sat Jan 10 20:14:54 2015):

The Server will shutdown now
The system is going down to maintenance mode NOW!

Shutdown cancelled.

7：重新启动时不进行磁盘检测

[root@db-server ~]# shutdown -fr now

Broadcast message from root (pts/1) (Sat Jan 10 20:23:59 2015):

The system is going down for reboot NOW!

8：在多少秒后关闭系统并给用户发送提示信息

[root@db-server ~]# shutdown -t 10 -h now "System will shutdown 10 sencond later"

Broadcast message from root (pts/1) (Sat Jan 10 20:33:36 2015):

System will shutdown 10 sencond later
The system is going down for system halt NOW!

你说的是XP自动关机设置吗？ 时间好象不是在这里设置的
时间设置我知道的是这个，比如你的电脑要在2:00关机，可以选择“开始→运行”，输入“at 2:00 Shutdown -s"，这样，到了2点电脑就会出现“系统关机”对话框，默认有30秒钟的倒计时并提示你保存工作。如果你想以倒计时的方式关机，可以输入“Shutdown.exe -s -t 7200"，这里表示2小时后自动关机，“7200"代表120分钟。

1、用法: shutdown [-i | -l | -s | -r | -a] [-f] [-m \\\\computername] [-t xx] [-c "comment"] [-d up:xx:yy] 没有参数 显示此消息(与 ? 相同) -i 显示 GUI 界面，必须是第一个选项 -l 注销(不能与选项 -m 一起使用) -s 关闭此计算机 -r 关闭并重启动此计算机 -a 放弃系统关机 -m \\\\computername 远程计算机关机/重启动/放弃 -t xx 设置关闭的超时为 xx 秒 -c "comment" 关闭注释(最大 127 个字符) -f 强制运行的应用程序关闭而没有警告 -d [u][p]:xx:yy 关闭原因代码 u 是用户代码 p 是一个计划的关闭代码 xx 是一个主要原因代码(小于 256 的正整数) yy 是一个次要原因代码(小于 65536 的正整数) 2、举例： 关闭计算机 shutdown –s （方法：”开始”->”运行”->”shutdown -s”->”确定”） 延迟3秒关闭计算机 shutdown –s –t 3（方法：”开始”->”运行”->”shutdown –s –t 3”->”确定”） 取消关闭计算机 shutdown –a （方法：”开始”->”运行”->”shutdown –a”->”确定”） 3、应用： (1)您如果想在1小时后自动关闭计算机，比如：您正在下载一个软件或一部电影，而您有急事要去丽水，您会怎么办？停止下载？太可惜了！继续？下载完后电脑怎么关闭？不用愁！您可以使用该命令解决： shutdown –s –t 7200 (系统在2小时后(7200秒)后关闭计算机，时间自定) (2)出现RPC漏洞而导致倒计时自动关机，使用该命令取消倒计时自动关机：

直接shutdonwn -s -t 7200 就是2小时后关机`!
-t 后面跟关机时间...- s 意思``关机`!
