在PowerShell中为命令执行计时

是的。

Measure-Command { .\do_something.ps1 }

注意,measure命令的一个小缺点是您没有看到stdout输出。如果要查看输出,则可以使用.NET秒表对象,例如:

$sw = [Diagnostics.Stopwatch]::StartNew()
.\do_something.ps1
$sw.Stop()
$sw.Elapsed

还可以从历史记录中获取最后一个命令并减去 EndExecutionTime 从其 StartExecutionTime .

.\do_something.ps1  
$command = Get-History -Count 1  
$command.EndExecutionTime - $command.StartExecutionTime

使用 Measure-Command

例子

Measure-Command { <your command here> | Out-Host }

管道到 Out-Host 允许您查看命令的输出,即 其他消费者 测量命令 .

简单模仿

function time($block) {
    $sw = [Diagnostics.Stopwatch]::StartNew()
    &$block
    $sw.Stop()
    $sw.Elapsed
}

然后可以作为

time { .\some_command }

您可能需要调整输出

这是我编写的一个函数,它的工作原理与Unix类似 time 命令:

function time {
    Param(
        [Parameter(Mandatory=$true)]
        [string]$command,
        [switch]$quiet = $false
    )
    $start = Get-Date
    try {
        if ( -not $quiet ) {
            iex $command | Write-Host
        } else {
            iex $command > $null
        }
    } finally {
        $(Get-Date) - $start
    }
}

使用秒表并格式化经过的时间:

Function FormatElapsedTime($ts) 
{
    $elapsedTime = ""

    if ( $ts.Minutes -gt 0 )
    {
        $elapsedTime = [string]::Format( "{0:00} min. {1:00}.{2:00} sec.", $ts.Minutes, $ts.Seconds, $ts.Milliseconds / 10 );
    }
    else
    {
        $elapsedTime = [string]::Format( "{0:00}.{1:00} sec.", $ts.Seconds, $ts.Milliseconds / 10 );
    }

    if ($ts.Hours -eq 0 -and $ts.Minutes -eq 0 -and $ts.Seconds -eq 0)
    {
        $elapsedTime = [string]::Format("{0:00} ms.", $ts.Milliseconds);
    }

    if ($ts.Milliseconds -eq 0)
    {
        $elapsedTime = [string]::Format("{0} ms", $ts.TotalMilliseconds);
    }

    return $elapsedTime
}

Function StepTimeBlock($step, $block) 
{
    Write-Host "`r`n*****"
    Write-Host $step
    Write-Host "`r`n*****"

    $sw = [Diagnostics.Stopwatch]::StartNew()
    &$block
    $sw.Stop()
    $time = $sw.Elapsed

    $formatTime = FormatElapsedTime $time
    Write-Host "`r`n`t=====> $step took $formatTime"
}

使用样本

StepTimeBlock ("Publish {0} Reports" -f $Script:ArrayReportsList.Count)  { 
    $Script:ArrayReportsList | % { Publish-Report $WebServiceSSRSRDL $_ $CarpetaReports $CarpetaDataSources $Script:datasourceReport };
}

StepTimeBlock ("My Process")  {  .\do_something.ps1 }

Measure-Command {echo "Good morning World!" | Write-Host}
