如何将Powershell变量传递给CMD命令？ [英] How can I pass a powershell variable into a CMD command?

问题描述

我正在尝试通过Powershell运行以下命令：

I am trying to run the following command through powershell:

schtasks /query /s $compname /v /fo csv | ConvertFrom-Csv

$ compname在powershell脚本的第一部分中设置，但不能传递给这样的命令。例如，当我尝试传递$ localhost时，出现以下错误：

$compname is set in the first part of the powershell script, but cannot be passed into the command like this. For example, when I try passing in $localhost, I get the following error:

ERROR: Invalid syntax. Value expected for '/s'.
Type "SCHTASKS /QUERY /?" for usage.

是否可以将变量传递给此命令？我不打算更改为Powershell的本机方式（通过COM对象）访问计划任务。

Is there a way to pass the variable into this command? I don't plan to change to powershell's native way to access scheduled tasks (through a COM object).

推荐答案

为我工作，已在v2中进行了测试。如果将变量用双引号引起来（例如 $ compname），是否有帮助？

Working for me, tested in v2. Does it help if you enclose the variable in double quotes (e.g "$compname") ?

$compname = 'localhost'
schtasks /query /s $compname /v /fo csv | ConvertFrom-Csv
