Timing a command's execution in PowerShell

Question

Is there a simple way to time the execution of a command in PowerShell, like the \'time\' command in Linux?
I came up with this:

$s=Get-Date; .\\do_somet         


        

Answer 1

Using Stopwatch and formatting elapsed time:

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"
}

Usage Samples

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

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