Microsoft releases PowerShell version 7.2
PowerShell is a task automation and configuration management program from Microsoft, consisting of a command-line shell and the associated scripting language.
 
In PowerShell, administrative tasks are generally performed by cmdlets (pronounced command-lets), which are specialized .NET classes implementing a particular operation. These work by accessing data in different data stores, like the file system or registry, which are made available to PowerShell via providers. Third-party developers can add cmdlets and providers to PowerShell. Cmdlets may be used by scripts, which may in turn be packaged into modules.
 
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.
 
Using Visual Studio Code for PowerShell Development
Visual Studio Code(VS Code) is a cross-platform script editor by Microsoft. Together with the PowerShell extension, it provides a rich and interactive script editing experience, making it easier to write reliable PowerShell scripts. Visual Studio Code with the PowerShell extension is the recommended editor for writing PowerShell scripts.
 
Shell
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
  • Supports command and parameter aliases
  • Pipeline for chaining commands
  • In-console help system, similar to Unix man pages
 
Scripting language
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
 
Configuration management
PowerShell Desired State Configuration (DSC) is a management framework in PowerShell that enables you to manage your enterprise infrastructure with configuration as code.
 
With DSC, you can:
  • Create declarative configurations and custom scripts for repeatable deployments
  • Enforce configuration settings and report on configuration drift
  • Deploy configuration using push or pull models
