A PowerShell PSDrive is a mapping between a PowerShell provider and a resource. The majority of our work is done in a file system PSDrive that corresponds to a file system drive. Let me show you a little trick that might come in handy with a PSDrive. My “trick” should apply to just about any…

PowerShell Pivot Tables
I was working on a question in the Ask Don and Jeff forum about multidimensional arrays. The ultimate goal of sorts was to create an HTML report that contained in essence a pivot table. This device allows you to slice and dice data so that you can identify trends or patterns. In PowerShell, there aren’t…
Friday Fun: Expand Environmental Variables in PowerShell Strings
This week I was working on a project that involved using the %PATH% environmental variable. The challenge was that I have some entries that look like this: %SystemRoot%\system32\WindowsPowerShell\v1.0\. When I try to use that path in PowerShell, it complains because it doesn’t expand %SystemRoot%. What I needed was a way to replace it with the…
PowerShell 3.0 Scheduled Jobs Slides and Demos
Yesterday I did a webinar for Idera on the new Scheduled Jobs feature of PowerShell 3.0. If you missed it, I believe you can go to http://www.idera.com/Events/RegisterWC.aspx?EventID=404 and view the archived webcast. I’m assuming that once you register you’ll be given a link for the webcast. In the meantime, I can also offer a PDF…
Find Required Services with PowerShell
Here’s a little PowerShell tidbit to get the status of all the required services. That is, the services that other services depend upon. When using Get-Service, this is the RequiredServices property which will be a collection of service objects. get-service | where {$_.status -eq “running”} | select -expand RequiredServices I’m intentionally omitting and results so…
Working with Access Rules in PowerShell
Yesterday I posted a function to create a summary report of ACL information using Windows PowerShell. I posted this in response to a question in the Ask Don and Jeff forum at PowerShell.com. I received an appreciative followup. The next step for this IT Pro it seems is to get a detailed list of the…
Get ACL Information with PowerShell
I got a question in the “Ask Don and Jeff” forum on PowerShell.com that intrigued me. The issue was working with the results of the Get-ACL cmdlet. The resulting object includes a property called Access which is a collection of access rule objects. Assuming you are using this with the file system, these are System.Security.AccessControl.FileSystemAccessRule…
TechEd 2012 Slides and Demos
At TechEd North America in Orlando, I presented a great session on Group Policy and Windows PowerShell. The session was entitled Group Policy Reporting and Analysis with Windows PowerShell. I co-presented with Group Policy MVP and guru Jeremy Moskowitz. Jeremy played the part of the “pointy-haired” boss, posing questions about Group Policy such as finding…
Get IP Addresses with PowerShell
In celebration of World IPv6 Day, I thought I’d post a little PowerShell code to return IP addresses for a computer. This information is stored in WMI with the Win32_NetworkAdapterConfiguration class. This class will return information about a number of virtual adapters as well so I find it easier to filter on the IPEnabled property….
Friday Fun: Another PowerShell Console Graph
Late last year I posted a demo script to create a horizontal bar graph in the PowerShell console. I liked it and many of you did as well. But I also wanted to be able to create a vertical bar graph, ie one with columns. This is much trickier since you have to tell PowerShell…
Group Policy Analysis and Reporting with PowerShell
In a few weeks I’ll be presenting at TechEd North America. I hope you already made plans to go because it is sold-out. On Wednesday, June 13th at 8:30AM I’ll be talking about Group Policy and PowerShell; specifically Group Policy Analysis and Reporting with PowerShell. This should be a lot of fun. I’m doing the…
Get My Variable Revisited
Last year I wrote a few articles on working with variables. One task I needed was to identify the variables that I had created in a given PowerShell session with a function I wrote called Get-MyVariable. I also posted an article on identifying the object type for a variable value. While trying to find something…
Query Local Administrators with WMI
I have a quick post today on using WMI to list members of the local administrators group. It is very simple to get the group itself with the Win32_Group class. PS S:\> get-wmiobject win32_group -filter “name=’Administrators'” Caption Domain Name SID ——- —— —- — SERENITY\Adminis… SERENITY Administrators S-1-5-32-544 But the class doesn’t have any methods…
Friday Fun: Get Latest PowerShell Scripts
Probably like many of you I keep almost all of my scripts in a single location. I’m also usually working on multiple items at the same time. Some times I have difficult remembering the name of a script I might have been working on a few days ago that I need to return to. The…
Introducing the ScriptingHelp PowerShell Module
Over the last few weeks I’ve posted articles on the different parameter validation options in Windows PowerShell. More than one person suggested consolidating the articles. That seemed like a good idea. There were a variety of ways to handle this but I wanted something more PowerShell-oriented. Then I realized, why not produce PowerShell About topics?…
