我们大多数人使用“开始”菜单来关闭Windows系统，但如果您选择使用命令行，是否可能造成损坏？有没有什么特别的命令会造成损害而其他命令不会？今天的超级用户问答帖子回答了一位忧心忡忡的读者的问题。

问题

超级用户读取器FlipFloop想知道使用Windows CMD关闭计算机是否会造成损坏：

When you launch shutdown -i to shut down a computer via the command prompt (CMD), does it damage the computer that is being turned off (either locally or remotely)?

使用Windows CMD关闭计算机会导致损坏吗？

答案

超级用户贡献者Marco Bonelli和LPChip为我们提供了答案。首先，Marco Bonelli：

The shutdown command in Windows performs a normal shutdown/reboot/logoff on the computer (locally or remotely). If you closed all of your running programs and saved your files, there is no difference between running any shutdown command (with any parameter) or using the Windows interface via the Start Menu. The command does not damage the computer or file system in any way.

More About Running Programs

If any programs preventing the shutdown are running, Windows will automatically try to terminate them and, if that is not possible, will prompt you about it. The only problem you can have here arises with programs performing unsaved changes to files. If they provide an automatic recovery of improperly closed sessi*** like Microsoft Office for example, they will save their state to recover it on the next start, otherwise you will lose the unsaved data.

接着是LPChip的答案：

No, it will not. When you use the Start Menu to shut down a computer, it will also use the same shutdown command, just with different parameters.

The shutdown -i option was made to expose features that the Windows Start Menu does not offer without use of the Command Line. For example, shutdown -i can be used to send a shutdown command to another computer.

In the same fashion that shutdown -i will not damage your computer, neither will shutdown -s -t 0.

There is also the -f option, which is used to force a shutdown. This will not damage your Windows system, but it may cause any unsaved data (such as an unsaved open word document) to be lost.

Normally, Windows will show you a dialog of some sort like, “There is a program preventing shutdown. Do you want to cancel or continue anyway?” A timeout will eventually abort the shutdown. With the -f option, instead of showing you the message, it will assume that you wish to continue anyway and close any remaining programs.
