In Detail

Windows PowerShell is a task-based command-line shell and scripting language designed specifically 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.

PowerShell is great for batch importing or deleting large sets of user accounts and will let you collect a massive amount of detailed system information in bulk via WMI (Windows Management Instrumentation).

Getting Started with PowerShell is designed to help you get up and running with PowerShell, taking you from the basics of installation, to writing scripts and web server automation. This book, as an introduction to the central topics of PowerShell, covers finding and understanding PowerShell commands and packaging code for reusability, right through to a practical example of automating IIS. It also includes topics such as installation and setup, creating scripts, automating tasks, and using Powershell to access data stores, registry, and file systems.

You will explore the PowerShell environment and discover how to use cmdlets, functions, and scripts to automate Windows systems. Along the way, you will learn to perform data manipulation and solve common problems using basic file input/output functions.

By the end of this book, you will be familiar with PowerShell and be able to utilize the lessons learned from the book to automate your servers.

Comments about oreilly Getting Started with PowerShell:

Mostly the examples are how to get lists of information about PowerShell commands. Not much for doing anything practical.

The first chapters let you get a directory of PowerShell commands and sort lists of commands. No practical applications.

The middle chapters give you an idea that PowerShell can be used to create an application and run it. You learn the commands but not what to do with them.

The example of importing TXT files and converting to CVS is weak. If you have a text file called "file.txt" you're ok. If you have a text file with spaces in the file name (e.g. "average output variances.txt") you're sunk. And if the content within the text file isn't formatted precisely, you'll have no idea what to do.

Care to move the contents of one directory to another? Not going to learn that here.

The last few chapters on WMI, CIM, IIS (web server administration) all fit in less than 20 pages, mostly filled with screen shots.

Don't expect a lot of how-to information in this book.

For $10 this might be a good reference of what PowerShell can do. But don't expect to be able to accomplish anything you have in mind when you wanted to learn PowerShell for whatever your application may be.
