Hide powershell output

Question

I have the following script:

param([Parameter(Mandatory=$true)][string]$dest)

New-Item -force -path "$dest\1\" -itemtype directory New-Item -force -path "$dest\2\" -itemtype directory New-Item -force -path "$dest\3\" -itemtype directory  Copy-Item -path "C:\Development\1\bin\Debug\*" -destination "$dest\1\" -container -recurse -force Copy-Item -path "C:\Development\2\bin\Debug\*" -destination "$dest\2\" -container -recurse -force Copy-Item -path "C:\Development\3\bin\Debug\*" -destination "$dest\3\" -container -recurse -force 

The script takes a string and copies all files and folders from the static origin path to the given root string, amending some folders for structure clarity.

It works fine but prints out the results from the "New-Item" commands and I would like to hide that. I've looked at the net and other questions on SE but no definitive answers to my problem were found.

In case someone is wondering - I am using "New-item" at the beginning in order to circumvent a flaw in PS' -recurse parameter not copying all subfolders correctly if the destination folder does not exist. (I.e. they are mandatory)

Answer 1

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
