How to do it...

Open a terminal window to show your friend the difference between the commands:

1. At the prompt, enter the following (point Get-ChildItem to any valid directory with a noticeable number of files):

PS> $AllAttributes = measure-command { gci $HOME/random/ -rec | select * }PS> # Verbose version: Measure-Command -Expression { Get-ChildItem $HOME/random -Recurse | Select-Object * }

2. And then, to compare, type in the following:

PS> $SelectAttributes = measure-command { gci $HOME/random/ -rec | select name, fullname, creationtime }PS> # Verbose version: Measure-Command -Expression { Get-ChildItem $HOME/random/ -Recurse | Select-Object Name, FullName, CreationTime }PS> ($allattributes - $selectattributes).totalmilliseconds
