The PowerShell Language
From this point on, this book varies from the usual format of many books on scripting languages, which try to explain scripting concepts instead of showing you actual working scripts. This book focuses on the practical applications of PowerShell.
It's assumed you have a basic understanding of scripting. In addition, because the PowerShell scripting language is similar to Perl, C#, and even VBScript, there's no need to spend time reviewing for loops, if...then statements, and other fundamentals of scripting.
Granted, there are some unique aspects to the PowerShell language, but you can consult the PowerShell documentation for that information. This is not a language reference book; it's about how PowerShell can be applied in the real world. For more detailed information about the PowerShell language, you can download the PowerShell User Guide from www.microsoft.com/downloads/details.aspx?
