Overview

PowerShell is a cross-platform command-line shell and scripting language developed by Microsoft. It provides a powerful automation framework for system administrators and developers to manage systems, automate tasks, and build infrastructure-as-code solutions.

The platform is available across Windows, Linux, and macOS, with multiple editions and supporting tools. PowerShell includes utility modules like Crescendo, PlatyPS, PSScriptAnalyzer, and SecretManagement, along with Desired State Configuration (DSC) for infrastructure automation. The PowerShell Gallery serves as the central package repository for community and official modules.
