Not much here for any price....WARNING THIS "BOOK" IS 46 PAGES LONG! It is so short it really should be called a pamphlet.

I feel cheated by buying this book. And who cares? It cost less than $9. BUT I have four other O Reilly Pocket Reference books and I concluded they are a great value especially since they are all priced around $8-11 each. All of them over 100 pages long and some close to 200 pages and packed full of very concise, organized information. For something around $10 per pocket reference and the amount of content per book - I concluded they are a GREAT value. THAT IS until I bought this "Sed and Awk: Pocket Reference" . I have developed the feeling that it can be faster to just grab a pocket reference and look it up - much like using a dictionary. Especially if you don't remember the exact command - thumbing thru one of these pocket references can be faster and more efficient then a web search. It can save time sorting thru a Google search or have pops up harassing you to join a forum. But you need some info in your pocket reference and since this thing is a total length of 46 pages there is not much here. And the Awk coverage begins on page 18 - so you get (46-18) or 28 pages of Awk. And after the 'regex' boiler plate info in the beginning of this book - about a dozen pages of Sed info. Since I have used Awk intensely on occasion - I feel there is a lot more to Awk then 28 pages. But I don't use Awk frequently enough to master it - so I really wanted a quick Awk and Sed reference. And this book is not that.
It is strange since I have Arnold Robbins Bash Pocket Reference and it is not bad at over 100 pages and I find it organized and useful. I use it for the occasional shell script. But I think Robbins is taking advantage of the good reputation of these other pocket references. I think it is important to note that he has written a 456 page "Effective Awk Programming" book for around $40 on Amazon. It is almost like Robbins is saying - "you want some reference on Awk? - then buy my $40 book otherwise here is a teaser book with a few pages on Sed and Awk". It seems very little effort was exerted in writing this "Sed and Awk" Pocket Reference. Since I was so happy with my other pocket references - I had high expectations and did not bother to read the product description that this 'book' is less than 50 pages. It is about 1/8 inch or 4mm thick - it is more like a pamphlet. So, I can't recommend this book.
