If you're looking at this, you know why you're looking at it, so not going to explain. It is good. 130 or so pages and most of it is commands that are useful for your run books. The book doesn't explain how to interpret the results, but if you can understand it and are comfortable on a shell, you can probably hazard a guess anyways, or Google it. A small amount of the commands are a tiny bit dated, which is expected with a print manual giving you commands for applications/OSes that are always changing, but even if dated, they at least give you the idea of what to run. Just go look up a good replacement application, or check the --help file for updated syntax. Really liked the IR checklist at the back, will incorporate some of that.

Its a book!

Format: Paperback

Obviously, comparable to RTFM, marketed as more geared to responders, or Windows domain admins with a small amount of Linux in their network. My review assumes you know what the book you are shopping for is, you have read or heard about the RTFM and this. Awesome book, you'll likely find or be reminded of something very useful that you can use tomorrow based on flipping through it. Good - What you'd expect, condensed, long listing of commands with brief descriptions. Network, firewall, registry, services, etc etc etc. Command based AV scanning and lots more. Lots of stuff is based on "Basic" commands included in powershell or windows cmd, additional tools sysinternals suite, some typical third party network command tools, as well a few references to less common tools. Eh - Frighteningly short intros to some tools, but for brevity's sake seems necessary, I'd suggest readers try everything in a lab. Bad - Many commands are described from a very basic idea gearing up to fairly complex, complete, long commands, with lots of big font and double spacing. Little to zero instruction is provided for some stuff, for example, the reg query commands, which you can read and see what they do or are for. Lots of lines go to nearly the exact same command (like firewall rules), I feel like they'ed be better if they had more context. The font is bigger (than RTFM), I'd like it if the book made more use of tables, bolding and underlining, and italicizing do differentiate sections of text, along with a smaller font and no double-spacing. I feel like this just adds to the girth of the book. All in all, great book, I definitely recommend it for network or domain admins and defenders.
