Placing Comment-Based Help

What an amazing event. I’m now reading through each of the Advanced entries in a vain attempt to whittle the entries down to a short list. It’s an incredibly difficult task, which is testament to your skill and diligence. We are so lucky to have so many competent scripters in the community.
As I read through the comments on each script, I’ve noticed several that say:
“Help should be nested under the function to work properly.”
Au contraire! This is not true and I want to make sure that people who see this comment are not misled. The Windows PowerShell team designed comment-based help to be really flexible.
As I explained in about_Comment_Based_Help, you can put comment-based help for a function in one of three positions:

  • At the beginning of the function body
  • At the end of the function body
  • On the line before the Function keyword

So, all of these work.

function Move-OldFiles { <# .Synopsis Moves old log files to an archive directory. #> Param ( [parameter(Mandatory=$true)] [String] $InputDirectory ) }function Move-OldFiles { Param ( [parameter(Mandatory=$true)] [String] $InputDirectory ) #Script logic goes here <# .Synopsis Moves old log files to an archive directory. #> }<# .Synopsis Moves old log files to an archive directory. #> function Move-OldFiles { Param ( [parameter(Mandatory=$true)] [String] $InputDirectory ) #Script logic goes here } If you place the comment-based help on the line before the Function keyword, make sure that there is, at most, one blank line between the end of the comment-based help and the line with the function keyword. To avoid this problem, I always make sure that there are no blank lines between the end of the comment-based help and the Function keyword.
When reading the comments about your solutions, please remember that we are all volunteers. Everyone who takes the time to comment on your solution is trying to help, and should be appreciated, but not every comment is correct. Trust, but verify!

PowerShell Escape Room

PowerShell Escape Room by Michiel Hamers

Why on earth you want to create an Escape Room with PowerShell as backend?

I’ve always been a fan of escape rooms, so I decided to create my own for my kids. I wanted to make it something that would be challenging and fun for them, but also educational. I decided to use PowerShell as the backend for the escape room, as I’m a PowerShell developer and I thought it would be a great way to learn more about the language.
The first step was to design the rooms. I wanted to make sure that there were a variety of puzzles and challenges that my kids would have to solve. I also wanted to make sure that the rooms were visually appealing and engaging. Once I had the rooms designed, I started building them.
I used a variety of materials to build the rooms, including wood, cardboard, and fabric. I also used a few electronic components, such as a USB extension cable with a switch and a 3-button keyboard. The USB extension cable with a switch was used to create a physical button that my kids could press to solve one of the puzzles. The 3-button keyboard was used to enter the code that my kids had to find to solve another puzzle.
I also used a few websites to create rebus puzzles that my kids had to solve. I printed out the rebus puzzles and placed them around the rooms. Once my kids had solved all of the puzzles, they were able to enter the code on a single screen to escape the room.
In this blog post, we’ll delve into the process of creating an engaging PowerShell escape room for the global PowerShell community. We’ll emphasize the significance of storytelling and provide a detailed breakdown of the PowerShell structure used for the escape room.
