PowerShell is a cross-platform task automation solution made up of a command-line shell, a scripting language, and a configuration management framework. PowerShell runs on Windows, Linux, and macOS.

PowerShell is a modern command shell that includes the best features of other popular shells. Unlike most shells that only accept and return text, PowerShell accepts and returns .NET objects. The shell includes the following features:

• Robust command-line history
• Tab completion and command prediction (See about_PSReadLine)
• Supports command and parameter aliases
• Pipeline for chaining commands
• In-console help system, similar to Unix man pages

As a scripting language, PowerShell is commonly used for automating the management of systems. It is also used to build, test, and deploy solutions, often in CI/CD environments. PowerShell is built on the .NET Common Language Runtime (CLR). All inputs and outputs are .NET objects. No need to parse text output to extract information from output. The PowerShell scripting language includes the following features:

• Extensible through functions, classes, scripts, and modules
• Extensible formatting system for easy output
• Extensible type system for creating dynamic types
• Built-in support for common data formats like CSV, JSON, and XML
