I was using the online copy of this book as they authors were still working on it。 Overall I think if you are new to powershell or if you ever learned enough to just get by， this book will be extremely helpful。 Especially the early chapters， the authors do a great job of explaining the fundamentals and how things work。 It really helped me understand some of the things I've been doing for years， the actual WHY I should or should not be doing them that way。 I think the book falls a little short on I was using the online copy of this book as they authors were still working on it。 Overall I think if you are new to powershell or if you ever learned enough to just get by， this book will be extremely helpful。 Especially the early chapters， the authors do a great job of explaining the fundamentals and how things work。 It really helped me understand some of the things I've been doing for years， the actual WHY I should or should not be doing them that way。 I think the book falls a little short on the MacOS and Linux side of things。 I think early on they did a good job of making sure to do examples for all platforms but from about halfway on they really focused on Windows。 Some of the functionality isn't there on the other platforms which isn't their fault but I do think some of it they could have shown as close as you can get on the other platforms。 They also did some examples with cloud resources， Azure specifically， early on which I thought was great but they again dropped it about halfway。 I would have really liked to have had more cloud resource Powershell scenarios。 Finally， there were some incorrect commands and typos。 I left comments which I'm sure they will fix before it's finalized。 。。。more
