Whitepaper : The Guide to Learning PowerShell

Microsoft’s Windows PowerShell is a task-based command-line shell and scripting language. It is an automation platform and scripting language that simplifies the management of Windows environments. It is designed primarily for system administration. It is becoming increasingly common as an automation tool for database administrators. Built on the .NET Framework, PowerShell controls and automates the management of the Windows operating system and the applications that run on Windows.

PowerShell provides an operating environment for commands that include cmdlets, functions, filters, scripts, aliases, and executables. PowerShell operates within a hosting application that exposes a command line to the user. It uses a host interface to communicate with the commands invoked by the command line. Utilize a console application, a Windows application, or a web application as the hosting application.

The electronic book with 20 chapters over three volumes provides a comprehensive introduction to PowerShell. This guide to learning PowerShell presents a wide range of topics with an abundance of knowledge. It introduces the PowerShell console, interactive PowerShell, variables, arrays and hash tables, the PowerShell pipeline, objects, conditions, loops, functions, scripts, and error handling. It also discusses scope, text and regular expressions, extensible markup language (XML), the file system, managing the Windows Registry, processes, services, and event logs, Windows Management Instrumentation (WMI), user management, and loading .NET libraries, and compiling the code.
