PowerShell Twitter Update [2013-02-24]

So it’s getting close the end of February, and it’s been several months since I’ve blogged anything new! For today’s post, let’s take a look at what’s going on, on Twitter in the PowerShell universe!

#ConEmu

@tphakala says that he’s discovered a project called #ConEmu. #ConEmu is a project hosted on Google Code and offers a PowerShell console replacement for Windows. Some of the features that #ConEmu includes are: tabbed console support, smooth / friendly window resizing, support for Windows 7 jump lists (cool!), and a lot more!

4Sysops by Jeff Hicks

@JeffHicks is working on Part 8 of his 4Sysops series for Microsoft Certified Professional (MCP) Magazine, which covers changing Windows service account credentials through WMI. This series covers several other topics within WMI that will certainly be of interest to a variety of Windows desktop and server administrators.

Infosec PowerShell Module

@nikhil_mitt is an information security expert, and mentioned on Twitter that he has a security toolkit known as Nishang. This project is hosted on Google Code similar to the #ConEmu project mentioned above. Nikhil was even kind enough to mention that he had used some of my code in this project, which I had no idea about before today (February 24th, 2013)! I’m quite honored to hear that he made good use of some code that I had written a while back. The code we’re talking about here is in the Remove-Update function, which removes Windows software updates from a particular system.

Using Get-Content like Cat

@proxb (Boe Prox) tweeted about an article written by @ScriptingGuys (Ed Wilson) that talks about how to use the Get-Content cmdlet in PowerShell v3 to track changes to text files in realtime. This command is similar to the “cat” command in *nix operating systems.

PowerShell: Getting an access token from Instagram (oAuth 2.0)

So I’ve recently been struggling with the first step of oAuth 1.0a, which is getting a “request token.” Twitter still uses oAuth 1.0a, and although they have fairly decent documentation on the authentication flow, I’m still having a rough time with it. I had read that supposedly oAuth 2.0 would be easier to work with than oAuth 1.0a, but that didn’t really matter to me since Twitter isn’t using oAuth 2.0 yet.

When push came to shove, and oAuth 1.0a was still giving me headaches, I figured I would just try out oAuth 2.0, to see how easy it was to get an access token. As it turns out, it’s REALLY FREAKIN’ easy, and you don’t have to worry about giving out your application’s consumer secret key (aka. consumer key, client secret, etc.), which is sensitive information. Rather, all you need to do is pass in your callback URL (the one that you configure on your application registration), and the consumer ID (aka. client ID) that the service provides you with.

PowerShell: Removing a list of computers from Active Directory

@Kid_Zer0 on Twitter recently asked the following question:

“Need to delete a list of computers from AD – anyone know how to do this in #PowerShell or #VBScript (List is from a file)”

I’ve previously written several versions of an Active Directory cleanup script, but if you’re not seeking something that complicated, you can simply leverage the cmdlets built into Microsoft Windows Server 2008 R2. This simple, one-liner command should take a list of computers from a text file, and remove them from Active Directory:

Get-Content ComputersToDelete.txt | % { Get-ADComputer -Filter { Name -eq $_ } } | Remove-ADComputer -WhatIf

Upon running this command, you should receive output similar to the following (my text file only has one computer account in it):

If you want the script to actually make changes, simply leave the -WhatIf off the end of the script. Keep in mind that this command also depends on the input text file to be in the local directory, otherwise you will need to specify the full path to the text file. Another assumption in this command, is that you are running the command from a server that is a member of the same domain that you want to remove accounts from. If you have a more complex Active Directory environment, you will need to use other parameters to specify the domain / forest, and credentials if necessary, that you need to act against.

Hope this helps!
