About PowerShell

Function Get-HelloWorld {
	Param(
		[Parameter(Mandatory=$false, Position=0)]
		[string]$Person = "World"
	)

	return "Hello, $Person!"
}

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 professionals and power users control and automate the administration of the Windows operating system and applications that run on Windows.

Windows PowerShell commands, called cmdlets, let you manage the computers from the command line. Windows PowerShell providers let you access data stores, such as the registry and certificate store, as easily as you access the file system. In addition, Windows PowerShell has a rich expression parser and a fully developed scripting language.

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.

PowerShell has been open sourced and when released, PowerShell Core 6 will be supported on Windows, Linux and MacOS.

Detailed documentation on many PowerShell concepts and features can be found at https://docs.microsoft.com/en-us/powershell

A tremendous learning opportunity to explore the depth of your own knowledge

Exercism is fantastic in learning new languages but that is not the extent of it. If you are a "more experienced" programmer you may have encountered impostor syndrome: the idea you don't really know what you think you know. Exercism lets you solve problems and put them in the space of open feedback which is a tremendous learning opportunity to explore the depth of your own knowledge. Even if you have been programming in a language for awhile it is worth checking into Exercism to see where you stand with current implementation practices.

Relaxed. Encouraging. Supportive.

I use Powershell daily to help get my work done. Love it for DevOps work on Windows and now on Linux.
Fun. Challenging. Interesting
