微软已经在Powershell的连接网站(2012-02-15 at 4:40 PM)上宣布，在3.0版本中，他们已经扩展了重定向来解决这个问题。

In PowerShell 3.0, we've extended output redirection to include the following streams: 
 Pipeline (1) 
 Error    (2) 
 Warning  (3) 
 Verbose  (4) 
 Debug    (5)
 All      (*)

We still use the same operators
 >    Redirect to a file and replace contents
 >>   Redirect to a file and append to existing content
 >&1  Merge with pipeline output

有关详细信息和示例，请参阅“about_Redirection”帮助文章。

help about_Redirection

powershell ".\MyScript.ps1" > test.log

Use:

Write "Stuff to write" | Out-File Outputfile.txt -Append

我认为你可以修改MyScript.ps1。然后试着像这样改变它:

$(
    Here is your current script
) *>&1 > output.txt

我刚刚用PowerShell 3试了一下。你可以像内森·哈特利的回答一样使用所有的重定向选项。

要在你的脚本中嵌入它，你可以这样做:

        Write-Output $server.name | Out-File '(Your Path)\Servers.txt' -Append

这样应该可以了。
