It works like a real stopwatch, and we control it using its methods, like Start(), Stop(), etc. The Measure-Command Cmdlet uses an object called. If you are serious about the performance variable, and want to keep the script block as clean as possible, we could elaborate our own function, and shape the output as we want. The count of even numbers in 1.100 is 50. Write-Host "The count of even numbers in 1.100 is $evenCount." TotalMilliseconds : 1.3838 Measure-Command -InputObject (1.100) -Expression $scriptBlock |
So we could assign the result to a variable, and work with it. We know that scripts executed with Measure-Object runs in the current scope. If your study also includes the result, there are two ways you can go about it. Measure-Command returns a System.TimeSpan object, but not the result from the script. Get-ChildItem C:\ -Filter SuperCoolFolder | Select-Object FullName Days : 0Īs a cool exercise, try figuring out why the output from New-Item didn’t show up.

Measure-Command returns an object of type System.TimeSpan, giving us more flexibility on how to work with the result. You can use $_ or $PSItem to access them.īesides the two parameters, objects in the pipeline are also passed to the script block. InputObject: Optional input to be passed to the script block.Expression: The script block to be measured.PowerShell has a built-in cmdlet called Measure-Command, which measures the execution time of other cmdlets, or script blocks. Measuring a script execution time is the first step towards script optimization. However, as your scripts become more sophisticated, and you need to work with complex data or big data sizes, performance becomes something to keep in mind. After all, scripts were made to run automation in the background. Most of the time while developing PowerShell scripts we don’t need to worry about performance, or execution time.
