如何在powershell脚本中执行cmd文件？ [英] How do I execute cmd file within powershell script?

问题描述

我想自动设置环境变量，而不先执行cmd，然后回显环境以显示环境变量的值。



我试过这个代码，我将值存储为我想要设置为环境变量的cmd文件。如果我想显示环境值，我必须先执行cmd文件。



我尝试过：

I want to set an environment variable automatically, without executing the cmd first, then echo the environment to show the value of the environment variable.

I tried this code, I store the value as cmd file that I want to set as an environment variable. If I want to show the environment value, I have to execute the cmd file first.

What I have tried:

Param(
    [Parameter(Mandatory)] [string] $FilePath,
    [Parameter(Mandatory)] [string] $Key,
    [Parameter(Mandatory)] [string] $Variable_Name,
    [Parameter(Mandatory)] [string] $Store
)

$Found = $False
$FileContents = switch -File $FilePath {
    $Key    { $Found = $True }
    default {
        if ($Found) {
            $_.Substring(1);
            break
        }
    }
}
$FileContents

$Path_Store = $Store
$Output = "set" + " " + $Variable_Name + "=" + $FileContents |
          Out-File $Path_Store\$Variable_Name.cmd -Encoding Ascii

我的期望，一旦我执行PowerShell脚本，我就可以直接显示环境变量

My expectation, once I execute the PowerShell script, I can directly show the environment variable
