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_something.ps1 ; $e=Get-Date; ($e - $s).TotalSeconds

But I would like something simpler like

time .\do_something.ps1

Answer 1

Yup.

Measure-Command { .\do_something.ps1 }

Note that one minor downside of Measure-Command is that you see no stdout output. If you want to see the output, then you can use the .NET Stopwatch object e.g.:

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

Answer 2

You can also get the last command from history and subtract its EndExecutionTime from its StartExecutionTime.

.\do_something.ps1
$command = Get-History | Select-Object -Last 1
$command = Get-History -Count 1
$command.EndExecutionTime - $command.StartExecutionTime
