How To Install PowerShell
The following article provides an outline for How To Install PowerShell. PowerShell is a task automation engine from Microsoft with a command-line shell and associated scripting language. Windows PowerShell is an open-source whose base source code is available on GitHub. It is built on a .NET framework, while the PowerShell Core is built on .NET Core. It helps administrators and IT professionals to automate system tasks, configure and manage operating systems such as Windows, Linux and macOS, and their applications and processes. Its equivalent in Linux is known as Bash Scripting. It is an object-oriented engine, i.e. it is based on objects. Commands of Windows PowerShell are called cmdlets which are .NET classes. These perform an action and, as output, returns an object that can be pipelined as an input to another command.
PowerShell functions are grouped together for managing particular tasks called PowerShell Modules. These modules allow administrators to reuse the script or code for the automation of a task. The host application for Windows PowerShell is the Integrated Scripting Environment (ISE). It can access command-line tools, .NET class libraries, and COM objects. There are many versions of PowerShell released till date. It was first made public in September 2003 at the Professional Developers Conference with the name Monad. All versions of Windows PowerShell are compatible with the previous versions of it.
