 What is PowerShell ?

Powershell consists of two parts: a command -line shell and a scripting language. It started out as a framework to automate administrative tasks in Windows.powershell has grown into a cross-platform tool That’S used for many kinds of tasks.

A command-line shell lacks a graphical interface, where you use a mouse to interact with graphical elements. Instead, you type text commands into a computer console. Here are some of Benefits of using a console:

 

• Interacting with a console is even faster than using a graphical interface.
• In console, you can run botches of commands, so it’s ideal for task automation for continuous-integration pipelines.
• You con use a console to interact with cloud resources and other resources.
• You con store commands and scripts in a tent file and use a source-control system. This capability is one of the biggest benefit,  because your commands are repeatable and auditable. In many systems, specially government systems, everything must be traced and evaluated a kaudited. Audit Cover everything

Features

PowerShell share some features with traditional shells.

• built-in help system-PowerShell offered a comprehensive help system that provides detailed information about commands and their pacesetters. This system often links to online resources for
  in-depth learning, making it easy for users to understand and utilize PowerShell effectively.
  
• Pipeline – one of the core concepts of PowerShell is pipeline.it allows for chaining multiple commands together, where the output of one command becomes input of the next. Unlike traditional shells that Operate on text,Power Shell works with objects, enabling more powerful and flexible operations.
  
• Aliases – to facilitate a smooth transition for users family with other shells, PowerShell supports aliases.

PowerShell differs from a traditional command-line shell in few ways:

• It operate object over text -PowerShell uses objects as input and output. Reducing the need for formatting and data extraction. This makes scripting more efficient compare  to tradition shells that rely on tent based input and output.
  
• PowerShell uses cmdlets – PowerShell uses cmdlets, Built on a common runtime, For consistent behaviour they typically take object input and return object output. Core cmdlets are built in .NET core I and open-source. PowerShell can be extended with custom cmdlets, scripts, and functions.
  
• It has many types of commands – PowerShell commands can be native executables, Cmdlets, functions, script, or aliases. Cmdlets are a type of command built on a common runtime.
