PowerShell如何将输出重定向到另一个PowerShell屏幕

本文关键字：PowerShell 另一个 屏幕 重定向 输出 | 更新日期: 2023-09-27 18:04:27

我需要能够将一些自定义输出从当前的PowerShell屏幕(你可以看到这有工作流)重定向到另一个PowerShell屏幕，这将是第一个(父)的子屏幕

注意**重定向到一个文件不是一个选项，因为它必须是"live"

所以我想知道它是否可以简单地在PowerShell中完成，或者在c#中打开流到子PowerShell进程。

谢谢

PowerShell如何将输出重定向到另一个PowerShell屏幕

我认为没有办法直接写入另一个控制台窗口。

最好的办法可能是创建一个脚本来监视对您创建的环境变量的更改。

然后，您可以使用Start-Process、Invoke-Item或其他一些方法(有几种方法可以做到这一点)在一个新的控制台窗口中启动该脚本。

或者您可以使用WPF或浏览器窗口而不是第二个控制台来创建UI元素。

你看过Powershell Jobs (help about_Jobs)吗?

仍然需要一些微调，但似乎工作
