But is THIS book any good? Yes. There are nine broad categories of hints, but little more organization than that, since not much is needed. There is no narrative; these are merely convenient references. And convenient they are: it immediately made itself useful in helping me memorize common ports with a simple list at about the middle of the book under "Networking" - great for future test scores, which unfairly demand memorization of what one normally finds via search engine these days. Anyway, here are the categories:
*NIX
WINDOWS
NETWORKING
TIPS AND TRICKS
TOOL SYNTAX
WEB
DATABASES
PROGRAMMING
WIRELESS
... along with references, an index and a clever conceit of plain old typewriter font all the way through.
Now, it may be annoying to some of you that elementary matters like the meaning of passwd or man are included among more difficult listings. Indeed, I didn't expect to see, under its own heading of "Updating KALI", the ordinary apt-get update and apt-get upgrade spelled out, but that sort of thing makes the book useful to the novice as well as to the more informed. For the latter group, there's things like, under "Native Windows Port Forward", the netsh one-liners that are hard to remember. There's about 20 Cisco commands all in one place, all of which I'd have to look up. And an awk-loaded nmap idea for reverse DNS lookup, which then organizes the results for clarity. And so on.
I'm happy I bought this one; it's continuing to prove useful to fill in the blanks of stuff I should have known by now, and is presented in a familiar and un-complex paper form. 4 stars out of four.
