Powershell Tutorial Online


Windows PowerShell is Microsoft's task automation framework, consisting of a command-line shell and associated scripting language built on top of .NET Framework. PowerShell provides full access to COM and WMI, enabling administrators to perform administrative tasks on both local and remote Windows systems.

Windows PowerShell includes the following features:

  • Cmdlets for performing common system administration tasks, such as managing the registry, services, processes, and event logs, and using Windows Management Instrumentation (WMI).
  • A task-based scripting language and support for existing scripts and command-line tools.
  • Consistent design. Because cmdlets and system data stores use common syntax and naming conventions, data can be shared easily and the output from one cmdlet can be used as the input to another cmdlet without reformatting or manipulation.
  • Simplified, command-based navigation of the operating system, which lets users navigate the registry and other data stores by using the same techniques that they use to navigate the file system.
  • Powerful object manipulation capabilities. Objects can be directly manipulated or sent to other tools or databases.
  • Extensible interface. Independent software vendors and enterprise developers can build custom tools and utilities to administer their software.

Output is Always a .NET Object Please, Remember that PowerShell output is always a .NET object. That output could be a System.Diagnostics.Process a object or System.IO.FileInfo object or a System.String object. Basically it could be any .NET object whose assembly is loaded into PowerShell including your own .NET objects.
