Powershell silent mkdir

PetSerAl is correct, added to by SimonS
Out-Null is your best bet but as SimonS stated > $null is quicker

Just to add another solution: mkdir returns an object and if I just execute the code below, I don't have any output. Further more, I can use $dir to make my own output if needed

$dir = mkdir c:\foo\bar

As a side note, I've tested this PowerShell Version

PS> $PSVersionTable.PSVersion
