Get-Learning – Introducing a new series of PowerShell Posts

I’ve been blogging here since 2009. In that time, I’ve tried to focus on surprising topics, or at least topics that were things I had recently learned or encountered. One big problem with that approach is that it makes it much more difficult to produce content. I really enjoy writing, and I’m teaching PowerShell very …

Calling Extension Methods in PowerShell

A quick one because it’s Friday night. I recently found myself translating some C# code into PowerShell.  If you’ve done this, you know that most of it is really routine.  Change the order of some things, change the operators, drop the semicolons. In a few places you have to do some adjusting, like changing using …

Specifying PowerShell Parameter Position

Positional Parameters Whether you know it or not, if you’ve used PowerShell, you’ve used positional parameters. In the following command the argument (c:\temp) is passed to the -Path parameter by position. The other option for passing a parameter would be to pass it by name like this: It makes sense for some commands to allow …

Missing the Point with PowerShell Error Handling

I’ve been using PowerShell for about 10 years now.  Some might think that 10 years makes me an expert.  I know that it really means I have more opportunities to learn.  One thing that has occurred to me in the last 4 or 5 months is that I’ve been missing the point with PowerShell error …

Celebrating Fake Internet Points in the PowerShell Community

This week, I (finally) hit 10,000 points on StackOverflow. On some level, I know it’s just fake internet points, but it’s a nice milestone. Like everyone I know in IT, I often find useful answers to questions I have on StackOverflow. Since there are so many answered questions on that site, I generally don’t even …

Voodoo PowerShell – VisioBot3000 Lives Again!

Back in January I wrote a post about how VisioBot3000 had been broken for a while, and my attempts to debug and/or diagnose the problem. In the process of developing a minimal example that illustrated the “breakage”, I noticed that accessing certain Visio object properties caused the code to work, even if the values of …

Get-Command, Aliases, and a Bug

I stumbled across some interesting behavior the other day as I was demonstrating something that I understand pretty well. [Side note…this is a great way to find out things that you don’t know…confidently explain how something works, and demo it.] I was asked to give an overview of how modules work in PowerShell. I’ve been …

Generating All Case Combinations in PowerShell

At work, a software package that I’m dealing with requires that lists of file extensions for whitelisting or blacklisting be case-sensitive. I’m not sure why this is the case (no pun intended), but it is not the only piece of software that I’ve used with this issue. What that means is that if you want …
