WMF 5.0 – Clipboard cmdlets

The April 2015 WMF 5.0 preview brings new functionality in the shape of cmdlets for working directly with the clipboard.

You use Set-Clipboard to put data onto the clipboard


£> get-command Set-Clipboard -Syntax

Set-Clipboard [-Append] [-WhatIf] [-Confirm] [<CommonParameters>]

Set-Clipboard [-Value] <string[]> [-Append] [-WhatIf] [-Confirm] [<CommonParameters>]

Set-Clipboard -Path <string[]> [-Append] [-WhatIf] [-Confirm] [<CommonParameters>]

Set-Clipboard -LiteralPath <string[]> [-Append] [-WhatIf] [-Confirm] [<CommonParameters>]


For instance:

Set-Clipboard -Value "test"


You can add text or files to the clipboard. Notice that you can use –Append to add to the clipboard content rather than overwriting any existing data.


The contents of the clipboard are retrieved using Get-Clipboard

£> Get-Clipboard -Raw


As well as raw data you can pull data in a number of formats.

£> Get-Command Get-Clipboard -Syntax

Get-Clipboard [-Format <ClipboardFormat>] [-TextFormatType <TextDataFormat>] [-Raw] [<CommonParameters>]


Format can be one of: Text, FileDropList, Image, Audio


TextFormat type can be one of:  Text, UnicodeText, Rtf, Html, CommaSeparatedValue


These all produce the same result:

£> Get-Clipboard -Raw


£> Get-Clipboard -TextFormatType Text
£> Get-Clipboard -Raw
£> Get-Clipboard -Format Text
£> Get-Clipboard -Raw


Notice how use the TextFormatType Text or Format Text cause get-Clipboard to be called again with the –Raw parameter


One obvious and useful tasking for the clipboard cmdlets is copying commands between PowerShell sessions:


On the source machine

£> Get-History -Id 43

  Id CommandLine
  -- -----------
  43 Find-Package -Name PSReadline -Source PSGallery | fl *


Set-Clipboard -Value (Get-History -Id 43 | select -ExpandProperty Commandline)


On the target machine:

Invoke-Expression -Command (Get-Clipboard -Raw)


This is one set of cmdlets that will generate many more uses as you experiment with them

WMF 5.0–New-TemporaryFile

Creating a temporary file in PowerShell 4.0 and earlier has been possible using a number of techniques such as:

£> $file = [System.IO.Path]::GetTempFileName()
£> $file


With the April 2015 WMF 5.0 preview this becomes much easier

£> $file2 = New-TemporaryFile
£> $file2

    Directory: C:\Users\Richard\AppData\Local\Temp

Mode                LastWriteTime         Length Name
----                -------------         ------ ----
-a----        4/30/2015  12:42 PM              0 tmp1FE1.tmp


Now you can create files simply and easily without having to remember the .NET syntax.


Notice that the temporary files are automatically created in your TEMP folder.

£> $env:TEMP

WMF 5.0 April 2015 Preview is available

The PowerShell team have released the April 2015 WMF 5.0 preview.  Details from

Blocksize missing?

I recently had a question asking why the Bloacksize property on Win32_LogicalDisk is empty but is populated on Win32_Volume.

The thing is to remember the underlying thing that these 2 CIM classes represent.


A logical disk is a subdivision of an extended partition. An extended partition can hold one or more logical disks.


When you create a volume on a disk you use either a primary partition or a logical disk from an extended partition. Until you format the volume you can’t have a block size as that is determined by the parameters you use to perform the format.


The documentation for Win32_LogicalDisk states that block size is not populated for logical disks

DSC is a major theme with the opening sessions covering this topic -  Don Jones on resource design and Jason Helmick on using DSC to deploy IIS and PWA.
