Measure execution time in PowerShell

Posted by Daniel Hölbling on October 13, 2010

I have no idea why, but although having been a Windows user for most of my career, I know the unix commandline pretty well. In fact, one of the best things in Powershell was the ls alias to the Get-ChildItem command.

Naturally, Microsoft could not include an alias for every unix command out there, so I spend a fair amount of time hunting down the Powershell equivalents to Unix commands whenever I need one.

This time it’s the time command that allows you to measure how long the execution of a particular command took. The Powershell equivalent is called Measure-Command and does exactly the same thing, returning a System.TimeSpan.

For example, to measure the execution time of a git checkout:

Measure-Command { git checkout gh-pages }

Switched to branch ‘gh-pages’

Days : 0

Hours : 0

Minutes : 0

Seconds : 0

Milliseconds : 344

Ticks : 3448544

TotalDays : 3,99137037037037E-06

TotalHours : 9,57928888888889E-05

TotalMinutes : 0,00574757333333333

TotalSeconds : 0,3448544

TotalMilliseconds : 344,8544

I considered creating an alias for Mesaure-Command to just time, but the usages are so rare that it’s not really necessary.
