PowerShell Deep Dives
Here is a quote of the description of the book from the Manning website:
PowerShell Deep Dives is a trove of essential techniques and practical guidance. It is rich with insights from experts who won them through years of experience. The book’s 28 chapters, grouped in four parts (Administration, Scripting, Development, and Platforms), were hand-picked by four section editors: Jeffery Hicks, Richard Siddaway, OisÃn Grehan, and Aleksandar Nikolić.
Whether you’re just getting started with PowerShell or you already use it daily, you’ll find yourself returning to this book over and over.
