PowerShell Basics Quick Reference Project

I noticed that I needed to quickly brush up on PowerShell and as a result, I decided to throw together a quick simple quick reference project to better familiarize myself with the PowerShell scripting language used primarily in Windows environments.

This quick reference project incorporates:

• Command line input parameters
• Reading from a JSON configuration file
• Writing to the console with Write-Host
• Flow control with if, elseif, and else
• Loop iteration with foreach
• Functions with parameters
• Exception handling and throwing with try, catch and finally
• Printing out errors using the $Error automatic variable
• Switch statements
• Enabling and disabling Set-PSDebug
• Unordered and ordered Hashtables
• Sorting unordered hashtables into sorted ordered hashtables
• Filtering out hashtable columns
• Writing to a CSV file
