Powershell 2.0写入输出以显示并追加到文件

Question

I would like to display a message in PowerShell and append the message to a log file. In PowerShell 4.0 you can use Tee-Object -Append but I don't think they have the -Append option in PowerShell 2.0. Is there an simple way to write a message to the screen and log file at the same time?

Unfortunately I can't upgrade to PowerShell 4.0.

Answer 1

You can use the Start-Transcript and Stop-Transcript cmdlets (remember to change the dropdown to 3.0 so you can see the 2.0 features). You might need to collapse your output file descriptors using redirection if you wish to capture verbose, warning, error, etc.

Answer 2

尽管有些长，但是可以使用：

    | %{write-host $_; out-file -filepath "$LOG" -inputobject $_ -append}
