Timing a command's execution in PowerShell

Yup.

Measure-Command { .\do_something.ps1 }

Note that one minor downside of Measure-Command is that you see no stdout output.

[Update, thanks to @JasonMArcher] You can fix that by piping the command output to some commandlet that writes to the host, e.g. Out-Default so it becomes:

Measure-Command { .\do_something.ps1 | Out-Default }

Another way to see the output would be to use the .NET Stopwatch class like this:

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

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

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

Use Measure-Command

Example

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

The pipe to Out-Host allows you to see the output of the command, which is otherwise consumed by Measure-Command.
