powershell - 如何在执行期间将 PowerShell 的输出重定向到文件

Question

我有一个 PowerShell 脚本，我想将其输出重定向到文件。问题是我无法更改该脚本的调用方式。所以我不能这样做:

 .\MyScript.ps1 > output.txt

如何在执行期间重定向 PowerShell 脚本的输出？

Answer 1

也许Start-Transcript适合您。如果它已经在运行，则首先停止它，然后启动它，完成后停止它。

$ErrorActionPreference="SilentlyContinue"Stop-Transcript | out-null$ErrorActionPreference = "Continue"Start-Transcript -path C:\output.txt -append# Do some stuffStop-Transcript

You can also have this running while working on stuff and have it saving your command line sessions for later reference.

If you want to completely suppress the error when attempting to stop a transcript that is not transcribing, you could do this:

$ErrorActionPreference="SilentlyContinue"
Stop-Transcript | out-null
$ErrorActionPreference = "Continue" # or "Stop"
