Writing and Publishing PowerShell Modules

Earlier in August we mentioned that modularity and abstraction are quite helpful. PowerShell modules can help enable these concepts. You might ask “Modules… why can’t I just write a function?” There are a number of benefits to bundling your functions into modules: Simplify code organization Group related functions together Share state between functions, but not with the user Re-use “helper functions” that you don’t want exposed to the user Improve discoverability: Find-Module MyModuleGet-Command -Module MyModule * Simplify distribution: Install-Module MyModule `Where does that last bullet come from?

Basic Exchange Monitoring

Hello Powershell.org! This is the first time I’ve posted for anyone outside of my own powershell blog site PowerShellMasters.com and I just want to thank PowerShell.org for everything they do for our community. I think most of you would agree that this site is one of the best PowerShell sites out there today and I am grateful for the opportunity to reach so many PowerShell people. OK enough with the touchy-feely stuff.

List users logged on to your machines

Password policies are the best 😀 Sometimes they lead to account logouts when someone forgets to logout of a session somewhere on the network though. It might be the TS session they use once a quarter for reporting or maybe you know the feeling when you RDP to a server only to find that it is locked by 2 other admins who forgot to logoff when they left. (Off cause this never happens… we all use PowerShell…) Anyway, this had me searching for a user session somewhere on the network.

Multithreading using jobs

Often I have had to check something against all servers or clients. A classic problem and every time I run into the it it’s time consuming and running the job multithreaded would be nice. A few years back I found a nice little script for multithreading which I have been using quite often. Unfortunately this wasn’t a module. And I can’t remember where it came from. So this week I set my mind on recreating this as a module and to see if I can publish it on PowerShell Gallery.

TEST IT: New IISAdministration Module

It’s no secret that Microsoft’s WebAdministration module isn’t universally loved. It’s functionality isn’t deep, and it doesn’t play well in the PowerShell pipeline. There are also a number of things in it that run really slowly, making bulk administration a pain. Last week, Baris Caglar announced that Windows 10 contains a new IISAdministration module, which is a rough draft of what is hoped to be a final module in Windows Server 2016.

Abstraction and Configuration Data

Modularity and abstraction are a huge benefit in scripting and coding. Which of the following blocks of code are easier to understand? $SQLConnection = New-Object System.Data.SqlClient.SQLConnection $SQLConnection.ConnectionString = 'Server=SqlServer1;Database=MyDB;Integrated Security=True;Connect Timeout=15' $cmd = New-Object system.Data.SqlClient.SqlCommand("SELECT * FROM Table1",$SQLConnection) $ds = New-Object system.Data.DataSet $da = New-Object system.Data.SqlClient.SqlDataAdapter($cmd) [void]$da.fill($ds) $SQLConnection.Close() $ds.Tables[0] Or… # Invoke-Sqlcmd2 -ServerInstance SQLServer1 -Database MyDB -Query 'SELECT * FROM Table1' If you aren’t a masochist, the latter probably looks a bit nicer.

Template based parsing and progress bars

Working with wifi I have often needed to do a survey of the surroundings, and therefor I loved that windows 7 (maybe even Vista) introduced more advanced netsh with wifi support. There’s a lot of useful information but it might be nice to have a more graphical overview. The thing is that a text blob like this is not very handy to work with. Some time late last year I heard a guy from the powershell team on the Powerscripting podcast talk about ConvertFrom-String and the new template based parsing.

Continuous Integration, Continuous Delivery, and PSDeploy

Are you starting to use version control at work? Are you being pestered by fellow PowerShell aficionados to start learning version control? Did you catch the PowerShell.org Crash Course in Version Control and pick up some Git and GitHub experience? Shameless plug, sorry : ) Version control is just the start. What if we want to automate testing? To deploy our files, folders, and other artifacts out to production or other environments?

What are variables anyway…

Fellow Admins. A quick chat if you’re new to variables. So if you’re like me and don’t know any other programing/scripting language then all this PowerShell stuff is a bit daunting. So to help, this articles is on PowerShell Variables. The thing is that Variables in PowerShell are very important. I’m assuming you know what a cmdlet is? The very basic underlying tools that make powershell work. They are like powershell building blocks or bricks in a PowerShell wall.

Introduction to Powershell

Hi Guys, I’m going to have a PowerShell ramble on a semi regular basis. What prompts me to write here on powershell.org is that I love powershell. I makes my job so much better. I’m an IT Pro and work for a large ish world spanning company. I mostly work with windows servers but get to work with other technology too. Like VMware and Citrix for example. The other thing I want to point out is that I’m not a programer.
