Introduction to Powershell

What is Powershell?

PowerShell is a powerful scripting language and command-line shell developed by Microsoft. It is built on the .NET framework and designed primarily for automating tasks and managing Windows-based systems. PowerShell is an object-oriented language, meaning it works with objects rather than just text, which allows for more efficient and complex scripting.
