Question

我在Windows Powershell中执行filename.exe（名称不相关）时遇到问题。 filename.exe可以很容易地从cmd执行，因为文件的路径被添加到PATH环境变量中。所以我可以从命令行执行这样的filename.exe：

filename arg1 arg2

我不知道如何在Powershell中这样做。

修改我尝试过同样的方法但没有成功。我收到了以下消息

    PS D:\> filename
filename : The term 'filename' is not recognized as the name of a cmdlet, function, script file, or operable program.
Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
At line:1 char:1
+ filename
+ ~~~~~~
    + CategoryInfo          : ObjectNotFound: (filename:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

如果您想为该会话添加环境变量，在本例中更新PATH，您可以使用System.Environment的SetEnvironmentVariable方法。

说，我想运行7zip，但其可执行文件的路径不在我的路径中。因此，如果我在Powershell中运行它，我将收到错误：

PS > 7z.exe
7z.exe : The term '7z.exe' is not recognized as the name of a cmdlet, function, script file, or operable program. Check
the spelling of the name, or if a path was included, verify that the path is correct and try again.
At line:1 char:1
+ 7z.exe
+ ~~~~~~
    + CategoryInfo          : ObjectNotFound: (7z.exe:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

让我们将其添加到路径中：

PS> [System.Environment]::SetEnvironmentVariable('PATH',$Env:PATH+';c:\program
files\7-zip')

现在再次运行：

PS > 7z.exe
