Get Started with PowerShell

What is PowerShell?

PowerShell is a command-line shell and scripting language from Microsoft for Windows, Linux, and macOS. It helps automate tasks and manage systems.

• Command-line shell: Interactive command prompt with rich features
• Scripting language: Write scripts (.ps1) to automate tasks
• Object-oriented: Commands (cmdlets) return objects, not just text
• Cross-platform: Works on Windows, Linux, and macOS (PowerShell 7+)
• Built on .NET: Uses the .NET runtime for functionality
• Extensible: Supports modules, functions, and custom cmdlets

Command Prompt vs Windows PowerShell vs PowerShell Core

• Command Prompt (cmd.exe): Windows-only legacy shell with text-based output and batch scripting (.bat/.cmd), still available for compatibility but not actively developed.
• Windows PowerShell 5.1: Windows-only object-based shell preinstalled on Windows, uses .NET Framework and verb-noun cmdlets, strong Windows integration but in maintenance mode with no new features.
• PowerShell 7+ (PowerShell Core): Cross-platform(available in Windows, Linux, macOS) object-based shell built on .NET Core, actively developed with modern features, recommended for new automation projects and runs alongside Windows PowerShell 5.1.

Installing PowerShell

On Windows:

• Windows PowerShell 5.1 is preinstalled in Windows 10 and Windows 11. No installation needed, just search for “PowerShell” in Start Menu.
• Install PowerShell using WinGet (recommended)
