#PSBlogWeek 4 – Supporting WhatIf and Confirm in Advanced Functions by Jeffrey Hicks

Jeffrey Hicks has written a great article for PSBlogWeek on how you can implement -WhatIf and -Confirm in your advanced functions, providing another level of assurance when testing commands. When I write tools for other team members, I always try to include the -WhatIf parameter, so they can get a level of comfort prior to issuing a command.

#PSBlogWeek 2 – Parameter Validation in Advanced Functions by Mike Robbins

Check out this great post by Mike Robbins, part 2 of #PSBlogWeek, covering basic parameter validation in PowerShell.

You don’t think much about parameter validation while writing scripts for yourself, but they’ll save you a lot of headaches once you start creating tools for other people to use. Properly used, parameter validation can make your script almost self-documenting for a new user, prompting them for the needed information.

If you missed it, be sure to check out Francis-Xavier Cat’s part 1 of #PSBlogWeek, discussing standard and advanced functions (and why you should be writing advanced functions).

Coming Soon

We’ll have some great content coming soon, but the most common question I get with PowerShell is, “What book do you recommend?” So, until I get some content up, the books I recommend:

Learn Windows PowerShell 3 in a Month of Lunches

If you’re new to Windows PowerShell, Learn Windows PowerShell 3 in a Month of Lunches is a great place to start. Each chapter is designed to be completed during a lunch break, sitting at your desk working through the chapters. The scripts you’ll write build on themselves each chapter, refining and improving as you go. A great introduction to the language.

PowerShell in Depth: An administrator’s guide

PowerShell in Depth: An administrator’s guide is a great book, covering the basics and way beyond. I find it indispensable as a reference tool, dog-earing my paper copy and searching my Kindle version quite often. Covers creating your own objects, advanced functions, working with .NET, working with databases, even building a GUI.

Learn PowerShell Toolmaking in a Month of Lunches

Learn PowerShell Toolmaking in a Month of Lunches is my favorite of the bunch. If you’re familiar with PowerShell and you regularly write scripts for other teams / administrators, you need this book. I’m obsessed with advanced functions, [CmdletBinding()], comment-based help, and write-output; so this is right up my alley. They cover proper tool design, ensuring your tool can work with a variety of inputs, as well as providing proper output that other commands can utilize. These techniques will take your scripting and reusable functions to a new level.
