Question

在下面摘录的我正在使用的函数中，有4个对Tee-Object cmdlet的调用。前3个将消息根据需要写入控制台和日志。第四个使用Write-Error，并且仅写入控制台。

# Run this step if the last step was successful...
if($script:BuildStepLastStatus -eq 0) {


    Write-Output $("`n" + "-"*100) | Tee-Object -FilePath  $script:BuildLogFileName -Append
    Write-Output ("[{0:yyyy-MM-dd hh:mm:ss tt}]: Step {1}..." -f (Get-Date), $StepName) | Tee-Object -FilePath  $script:BuildLogFileName -Append

    try {
        . $ScriptBlock | Tee-Object -FilePath  $script:BuildLogFileName -Append
    }
    catch {

        # Show the error details whether we will continue on error or not...
        Write-Error "$($_)`n" | Tee-Object -FilePath  $script:BuildLogFileName -Append

        if($ContinueOnError.IsPresent) {
            # 0 = success
            $script:BuildStepLastStatus = 0
        }
        else {
            # 1 = error condition
            $script:BuildStepLastStatus = 1
        }
    }
}

如何修改此代码以将错误写入控制台和日志？

Answer 1

AFAIK，Tee-Object接受输出流中的内容，因此错误流中的错误将被忽略。您可以做相反的事情。

"$($_)`n" | Tee-Object -FilePath  $script:BuildLogFileName -Append | Write-Error
