IHeartPowerShell.com In 2016 And Beyond

I have been neglecting this blog for nearly three years. PowerShell has changed a lot in three years from workflow to desired state configuration and classes. PowerShell is well on its way to becoming the must know language for the Microsoft automation platform. Even that may change as Microsoft continues to push into providing their frameworks and tools for non-Microsoft platforms PowerShell will be usable everywhere. But if you are still following this blog, you probably already know that so I digress...

Even though I haven't shared on this blog what I have been doing with PowerShell, I am still using it almost daily. Even as my job changed from a sysadmin/engineer to a solutions architect I still find myself using PowerShell to either analyze data or implement a proof-of-concept idea. I still evangelize to anyone that will listen the importance of automation and the capabilities PowerShell brings in this DevOps culture.

I will start sharing snippets of some of the work I have been doing over the last three years and the insight that comes in the future.

For now, you can check out a module I posted to the PowerShell Gallery that handles data encryption using certificates. I built this specifically from my experience dealing with DSC credential in files so they can be stored in source control. Feel free to contribute to or get the source over on GitHub

PowerShell SupportsShouldProcess Worst & Best Practices

This has been a very big discussion within the Scripting Games 2013 community and I want to add my two cents in an official blog post.

I've left several people comments on how they might be misunderstanding how SupportsShouldProcess works, but I also realize, everyone of these individuals has given me more insight into its use and perhaps, how it should best be utilized.

For those of you that don't know, SupportsShouldProcess is a parameter on the CmdletBinding attribute you can place on your cmdlets that automatically adds the -WhatIf and -Confirm parameters. These will naturally flow into other cmdlets you use that also SupportsShouldProcess, e.g. New-Item, Move-Item.

The major discussion has been around, should you just let the other cmdlets handle the $PSCmdlet.ShouldProcess feature, and if not how should you implement it. ShouldProcess has the following definitions.

FIM 2010 R2 Self-Service Password Reset Auto-Registration

I have been working on our FIM 2010 R2 SP1 lab environment looking for ways to simplify some of the overly complicated scenarios we had to implement to workaround the limitations in FIM 2010. One of those workarounds was the auto-registration of SSPR for new employees. When we onboard a new employee, we want to create a simple SSPR for them to get their first-time password reset.

Prior to the R2 release we were using the http://fim2010client.codeplex.com/ client and PowerShell to complete the registration process on a daily schedule. I was working on converting this to use the R2 registration cmdlets and combined it with PowerShell 3.0 Workflows to get to a solution similar to this.

PowerShell Error Handling Behavior Debunked

Note: I am using simple error messages as an example, please reference the best practices and guidelines I outlined on when to use custom error messages.

I have been churning in my mind for the last few days all the entries in the 2013 Scripting Games and how they handle errors, or lack thereof.

I am coming to the conclusion through some testing that the simple fact of seeing a try..catch or throw statements does not mean there is proper error handling.

I've been testing several variations and forms of error handling, so lets start with the basics.
function Test-WriteError {      [CmdletBinding()] param()  "Test-WriteError::ErrorActionPreference = $ErrorActionPreference"Move-Item -Path 'C:\Does\Not\Exists.log' -Destination 'C:\No\Where'"Test-WriteError::End"}   Test-WriteError::ErrorActionPreference = Continue
Move-Item : Cannot find path 'C:\Does\Not\Exists.log' because it does not exist.
