.psd1 files are usually used as module manifests

You can test the manifest

PS>  Test-ModuleManifest -Path ‘C:\Program Files\WindowsPowerShell\Modules\Pester\3.4.0\Pester.psd1’ | fl

Description       : Pester provides a framework for running BDD style Tests to execute and validate PowerShell commands inside of PowerShell and offers a powerful set of Mocking Functions that allow tests to mimic and mock the  functionality of any command inside of a piece of powershell code being tested. Pester tests can execute any command or script that is accesible to a pester test file. This can include functions, Cmdlets,  Modules and scripts. Pester can be run in ad hoc style in a console or it can be integrated into the Build scripts of a Continuous Integration system.

which in some ways is more useful as you can easily see what is actually in the manifets rather than dealing with a lot of empty properties.

You can create .psd1 files to hold other data and read them with Import-PowerShellDataFile. Default parameters for your favourite cmdlets is one thing that comes to mind

PowerShell 5.1 preview

Richard Siddaway Richard Siddaway Profile: Richard Siddaway
Powershell

Windows 10 shipped with PowerShell 5.0 installed. The latest preview builds, and presumably, next months anniversary update have had PowerShell 5.1. Windows 2016 TP5 also ships with PowerShell 5.1

A PowerShell 5.1 preview is now available for Windows 7, 8.1, 2008 R2, 2012 and 2012 R2

Parallel copy files over remoting session

Richard Siddaway Richard Siddaway Profile: Richard Siddaway
Powershell

In response to this post – https://richardspowershellblog.wordpress.com/2015/05/28/copy-files-over-ps-remoting-sessions/

I was asked how you could copy files in parallel to multiple machines.

As soon as anyone mentions parallelism I think of workflows so I ended up with this

$computers = ‘W16TP5TGT01’, ‘W16TP5TGT02’

workflow parallelcopy {
param ([string[]]$computername)
foreach -parallel ($computer in $computername) {
InlineScript {
$s = New-PSSession -ComputerName $using:computer
Copy-Item -Path C:\Scripts\New-NanoMachine.ps1 -Destination C:\Source -ToSession $s
Remove-PSSession -Session $s
}
}
}

parallelcopy -computername $computers

A couple of issues I found. First off –Tosession and –FromSession haven’t been added to the Copy-Item workflow activity. This means you have to use an Inline script block to access those parameters

Secondly accessing a emoting session created outside of the workflow generates a session busy error when trying to perform the copy so have to move the session creation into the Inline script.

If you had a lot of files, or a lot of data, to copy to multiple machines this approach may be worthwhile. For small amounts of data then the approach in the original article is probably best.

Biggest innovation in PowerShell is…

Richard Siddaway Richard Siddaway Profile: Richard Siddaway
Powershell

The imminent arrival of PowerShell 5.1 in the Windows 10 Anniversary update (assumption as the Windows 10 Insider previews have been showing PowerShell 5.1 for some time) and Windows Server 2016 (TP5 shows PowerShell 5.1) and the fact that PowerShell was officially released to the world 10 years ago come November started me thinking about what has been the biggest innovation in PowerShell over those 10 years.

Contenders that come to mind include:

– Remoting
– PowerShell modules
– CIM & CIM sessions
– Workflows
– Job engine
– Desired State Configuration
– PowerShell Gallery and package management
– PowerShell classes
– JSON support in PowerShell
– Internationalisation
– Error handling – try/catch
– Debugging enhancements
– REST API and Odata support
– PowerShell support for Microsoft products
– PowerShell support from third part vendors
– PowerShell community

Which do you think?

Or is it something else?

Leave a comment as I’m intrigued as to what people think has been the biggest PowerShell innovation

Summer goodies

Richard Siddaway Richard Siddaway Profile: Richard Siddaway
Windows 10, Windows Server 2016

Looks like we’re set for some summer goodies over the next few months.

First up is Windows 10 anniversary update that’s due 2 August

https://blogs.windows.com/buildingapps/2016/07/12/windows-10-anniversary-sdk-preview-build-14388-released/

Followed by the Windows Server 2016 launch at the end of September

https://blogs.technet.microsoft.com/windowsserver/2016/07/12/windows-server-2016-new-current-branch-for-business-servicing-option/

TP5 is stated to be feature complete – my testing so far shows some rough edges. Hope launch means general availability and not another 2-3 month wait like we had with Windows 2012 R2

The article is also interesting for showing how Windows server and Nano server will be treated differently. Windows server wil get patches in the traditional cycle we’ve come to know and love(?). Nano server will be more like Windows 10 with updates 2-3 times per year – including new features. Hopefully that would include Nano server being able to support more roles
