powershell - 将Write-Host语句重定向到文件

Question

我有一个正在调试的PowerShell脚本，想将所有Write-Host语句重定向到一个文件。有一个简单的方法吗？

Answer 1

Until PowerShell 4.0, Write-Host sends the objects to the host. It does not return any objects.

Beginning with PowerShell 5.0 and newer, Write-Host is a wrapper for Write-Information, which allows to output to the information stream and redirect it with 6>> file_name.

但是，如果您有很多 Write-Host语句，请将它们全部替换为 Write-Log，它使您可以决定是输出到控制台，文件还是事件日志，还是全部输出到这三个。
另请检查:

Add-Content

redirection operators像>, >>, 2>, 2>, 2>&1

Write-Log

Tee-Object

Start-Transcript 。
