What is PowerShell? A Beginner’s Guide

Introduction

If you’ve ever used the Windows Command Prompt, you know it can handle basic commands like navigating folders or pinging a website. But what if you want something much more powerful — something that can automate tasks, manage servers, control cloud environments, and even run scripts across Windows, Linux, and macOS?

That’s where PowerShell comes in.


What is PowerShell?

PowerShell is a task automation and configuration management framework from Microsoft. It’s made up of:

  1. A command-line shell – where you type commands.
  2. A scripting language – for writing scripts to automate repetitive tasks.

Unlike Command Prompt (which only deals with plain text), PowerShell is object-oriented, meaning it works with rich data objects instead of just text strings. This makes it much more powerful and flexible.


Key Features of PowerShell

  • Cross-platform: Runs on Windows, Linux, and macOS.
  • Cmdlets: Uses special built-in commands called cmdlets (pronounced command-lets). Example: Get-Process.
  • Automation: Helps you automate tasks like creating users, managing files, configuring servers, or even deploying apps to the cloud.
  • Integration: Works seamlessly with Microsoft technologies (Azure, Active Directory, Office 365), and also supports tools like AWS, VMware, and Docker.
  • Scripting: Lets you create powerful automation scripts using .ps1 files.
