Adam Bertram has a series on creating Powershell modules:

In this guide, we’ll create a PowerShell module for gathering computer hardware information. This module will help system administrators collect and report on memory, storage, and processor details across multiple systems.

Our module will feature:

• Functions to gather specific hardware information
• Remote system support using PowerShell sessions
• Standardized output format for consistent reporting

Patrick Gruenauer runs a script:

PowerShell scripts can be executed locally or remotely. In this article I will show how scripts can be executed remotely. It is important whether the script is on the source computer or on the target computer. Both scenarios are possible. Let’s dive in.

Adam Bertram is spinning in circles:

One of PowerShell’s key features is its ability to loop through data collections, enabling you to execute a code block repeatedly.

In this tutorial, we will explore three fundamental loop structures in PowerShell: foreach, for, and do loops.

By the end of this tutorial, you will have a solid understanding of how to use these loops to handle repetitive tasks and process collections of data more effectively.

Denny Cherry triggers an action:

Sometimes, you want/need to have PowerShell do an action, but it’s hard to do through PowerShell, or it can’t be done at all. If the website If This Then That (IFTTT) can do it instead, you can still do it through PowerShell, with a little extra work. The way to do this will be to call a webhook on an IFTTT Applet and pass the information you need to send to the third-party service. A great example of this would be if you need to automate posting a new post to FaceBook. Posting to Facebook is shockingly hard as you have to write all the pieces to post to Facebook manually, and there’s no current way to post to Facebook via PowerShell. However, you can call an IFTTT Action and have that action do the actual posting to Facebook for you.

Vlad Drumea shreds a file:

In this post I’ll go over some examples of how to parse log files with PowerShell, specifically my blog’s raw access log from cPanel.

Vlad shares several examples and explains the Powershell scripts. Most of them boil down to writing the correct regular expression and summing up results.

Adam Bertram differentiates the two:

Whenever you execute or run anything in PowerShell, you’re running a “command.” A command is an informal term for executable code, which can be a built-in PowerShell cmdlet, a custom function, or even an object method.

Cmdlets are compiled executable code provided by Microsoft, created in a language like C#, compiled, and added to a PowerShell module by software developers. Functions, on the other hand, are created directly in PowerShell by users. Although functions and cmdlets are technically different, they can be thought of as similar when you’re starting out.

Read on for more information, including a demo. I normally call them all cmdlets, but apparently I’ve been doing it wrong all this time.
