The final part of displaying PowerShell output is a hidden background call to an Output cmdlet, by default as the last part of the execution process PowerShell calls the default output cmdlet which is typically Out-Host.


Discarding output that you don't need:

PS C:\> get-childitem | out-null

An alternative method, which runs much faster is to use the $null automatic variable:

PS C:\> get-childitem > $null
PS C:\> $null = get-childitem

Another alternative, which also runs much faster is to use the [void] cast:

PS C:\> [void] (get-childitem)
