文件的要求是：每天晚上10点关机，第2天的8点开机，因为我不会用crontab命令，先谢谢了！！！因为老板要求每天关机，怕发火，因为公司发过一次火，所以要求关机

关机容易，开机用手动吧。

whitecat

crontab -e增加一行
0 22 * * * shutdown
根据情况自已修改关机命令

开机不知道行不行

whitecat

关机了crontab还怎么运行啊。如果主板支持的话可以考虑网络唤醒。

System AutoShutdown and AutoWakeup Controls

You can use the Dtpower program to specify times for your system to shut down automatically. This feature is called AutoShutdown. If you have a sun4u desktop machine, you can also set your system to power on automatically at a specified time. This feature is called AutoWakeup.


--------------------------------------------------------------------------------

Note - Read "Choosing to Use Suspend-Resume" before you change the AutoShutdown settings.


--------------------------------------------------------------------------------

AutoShutdown uses the Suspend feature to automatically power off your system. When the system powers up again, the system resumes in the state in which the system was suspended.

Through the Dtpower window, you can activate or deactivate the AutoShutdown and AutoWakeup features. You can also specify the following values:

The number of minutes of idle time before AutoShutdown attempts to suspend the system

The start and finish times when AutoShutdown can occur during each day. If you specify the same time for both start and finish, AutoShutdown can occur at any time of day. See Figure 23-11.

The time of day when the system automatically powers on and resumes (AutoWakeup) after being suspended by AutoShutdown. This feature is only available on sun4u desktop systems.

Figure 23-11 AutoShutdown Configuration for All Day



Note - AutoWakeup does not occur after you suspend a system manually. AutoWakeup can occur only after an AutoShutdown.


--------------------------------------------------------------------------------

To Set an Idle Time for AutoShutdown
Start Dtpower.


--------------------------------------------------------------------------------

Note - Consecutive executions of AutoShutdown do not occur less than five minutes apart, even if the idle time setting is under five minutes.


--------------------------------------------------------------------------------

In the Dtpower basic window, click More.

The window expands to show the Quick Edit tab.

In the Quick Edit tab, check Enable AutoShutdown.

Click Edit.

The AutoShutdown window is displayed.

In Figure 23-12, the AutoShutdown occurs after 1 hour of idle time between the hours of 6:00 p.m. and 8:00 a.m.

Click OK when all the settings you want are displayed.

If you want to reject the displayed settings, select Cancel. The currently active settings are displayed in the window.

To Disable AutoShutdown
