Windows PowerShell is a task-based command-line shell and scripting language designed especially for system administration. Built on the .NET Framework, Windows PowerShell helps IT Administrators control and automate the administration of the Windows operating system and applications that run on it.
Windows PowerShell is a task-based CMD shell and scripting language designed and built on .NET Framework.
PowerShell helps system administrators and power-users rapidly automate tasks that manage operating systems (Linux, macOS, and Windows) and processes. It’s commands let you manage computers from the command line. PowerShell providers let you access data stores, such as the registry and certificate store, as easily as you access the file system. PowerShell includes a rich expression parser and a fully developed scripting language.
Windows PowerShell design goals
PowerShell is designed to improve the command-line and scripting environment by eliminating long-standing problems and adding new features.
PowerShell makes it easy to discover its features. For example, to find a list of cmdlets that view and change Windows services
Managing systems can be a complex task. Tools that have a consistent interface help to control the inherent complexity. Unfortunately, command-line tools and scriptable Component Object Model (COM) objects aren’t known for their consistency.
The consistency of PowerShell is one of its primary assets. For example, if you learn how to use the Sort-Object cmdlet, you can use that knowledge to sort the output of any cmdlet. You don’t have to learn the different sorting routines of each cmdlet.
Additionally, cmdlet developers don’t have to design sorting features for their cmdlets. PowerShell provides a framework with the basic features that forces consistency. The framework eliminates some choices that are left to the developer. But, in return, it makes the development of cmdlets much simpler.
Interactive and scripting environments
The Windows Command Prompt provides an interactive shell with access to command-line tools and basic scripting. Windows Script Host (WSH) has scriptable command-line tools and COM automation objects, but doesn’t provide an interactive shell.
PowerShell combines an interactive shell and a scripting environment. It can access command-line tools, COM objects, and .NET class libraries. This combination of features extends the capabilities of the interactive user, the script writer, and the system administrator.
PowerShell is based on object not text. The output of a command is an object. You can send the output object, through the pipeline, to another command as its input.
This pipeline provides a familiar interface for people experienced with other shells. PowerShell extends this concept by sending objects rather than text.
Easy transition to scripting
PowerShell’s command discoverability makes it easy to transition from typing commands interactively to creating and running scripts. It transcripts and history make it easy to copy commands to a file for use as a script.
PowerShell Explained Further
Windows PowerShell is a command-line shell and scripting language designed especially for system administration. Its analogue in Linux is called as Bash Scripting. Built on the .NET Framework, It helps users to control and automate the administration of the Windows operating system and applications that run on Windows Server environment.
Windows PowerShell commands, called cmdlets, let you manage the computers from the command line. It providers let you access data stores, such as the Registry and Certificate Store, as easily as you access the file system.
In addition, it has a rich expression parser and a fully developed scripting language. So in simple words you can complete all the tasks that you do with GUI and much more. It’s Scripting is a fully developed scripting language and has a rich expression parser.
Features of Windows PowerShell
Cmdlets − Cmdlets perform common system administration tasks, for example managing the registry, services, processes, event logs, and using Windows Management Instrumentation (WMI).
Task oriented − PowerShell scripting language is task based and provide supports for existing scripts and command-line tools.
Consistent design − As cmdlets and system data stores use common syntax and have common naming conventions, data sharing is easy. The output from one cmdlet can be pipelined to another cmdlet without any manipulation.
Simple to Use − Simplified, command-based navigation lets users navigate the registry and other data stores similar to the file system navigation.
Object based − It possesses powerful object manipulation capabilities. Objects can be sent to other tools or databases directly.
Extensible interface − PowerShell is customizable as independent software vendors and enterprise developers can build custom tools and utilities using PowerShell to administer their software.
PowerShell variables are named objects. As it works with objects, these variables are used to work with objects.
All the tools are basically developed by Microsoft to ease the use of IT and also to make us understand the Information Technology. One of the best software made by Microsoft is Office which helps businesses and non-business users to work efficiently and make work simple.
