About the Technology

Windows PowerShell transformed the way administrators and developers interact with Windows. PowerShell, an elegant dynamic language from Microsoft, lets you script administrative tasks and control Windows from the command line. Because it's a full-featured, first-class Windows programming language, programmers and power-users can now do things in a shell that previously required VB, VBScript, or C#.

It includes full chapters on these topics and also covers new language elements and operators, events, Web Services for Management, and the PowerShell Integrated Scripting Environment.

The First Edition's coverage of batch scripting and string processing, COM, WMI, and .NET have all been significantly revised and expanded. The book includes many popular usage scenarios and is rich in interesting examples that will spark your imagination. This is the definitive book on PowerShell v2!
