Greg Moore walks us through Powershell’s ability to display help info:
Shortly after writing my last article on Parameters, I had to update a script, and I wanted to make it easier for others to run. One of the features I wanted to add was the ability to show them what the script would do with the provided parameters without actually running the script, in other words, provide “help”.
There is a thoughtful way to do this, and Greg walks us through it, while also showing us a few false starts along the way.
