通过cmd命令解压缩文件（7-zip） [英] Unzip files (7-zip) via cmd command

问题描述

我尝试通过CMD解压缩文件。

I try to unzip a file via CMD.

所以我安装winzip（及其插件cmd），winrar和7-zip。

So I install winzip (and its plugin to cmd), winrar and 7-zip.

但是当我尝试通过CMD 执行命令时：

But when I try to execute a command via the CMD:

7z e myzip.zip

b $ b

它给出下一个错误：

It gives the next error:

7z is not recognized as an internal or external command

此外，我将7-z的文件夹添加到环境变量（属性 - >高级 - >环境变量 - >用户变量 - >选择路径，并添加 C：\Program Files\7-Zip

In addition, I added the folder of 7-z to the environment variables (Properties--> advanced --> Environment Variables --> user variable --> choose path, and add C:\Program Files\7-Zip

可能的原因是什么？

推荐答案

在命令提示符中执行以下操作适用于我，环境变量也很好：

Doing the following in a command prompt works for me, also adding to my User environment variables worked fine as well:

set PATH=%PATH%;C:\Program Files\7-Zip\
echo %PATH%
7z

您应该看到输出类似 - 这是在我的笔记本电脑上运行Windows 7）：

You should see as output (or something similar - as this is on my laptop running Windows 7):

C:\Users\Phillip>set PATH=%PATH%;C:\Program Files\7-Zip\

C:\Users\Phillip>echo %PATH%
