Hide powershell output

Question

Option 1: Pipe it to Out-Null

New-Item -Path c:\temp\foo -ItemType Directory | Out-Null
Test-Path c:\temp\foo

Option 2: assign to $null (faster than option 1)

$null = New-Item -Path c:\temp\foo -ItemType Directory
Test-Path c:\temp\foo

Option 3: cast to [void] (also faster than option 1)

[void](New-Item -Path c:\temp\foo -ItemType Directory)
Test-Path c:\temp\foo
