This is not a book I liked, however it may be good for you.
This is a book about solving problems with shell scripts, the style may be what you like, but I did not like the style and gave up reading half way though and only skimmed the second half of the book.
You need to know the following and then decide if it's for you:
I did not like the book because the code chunks were too long for a printed book and there was not enough discussion about why things worked and how they worked. Additionally there were not enough recipes, I much prefer the O'Reilly cookbook series books.
I also felt that I would not choose shell to solve some of the problems, for example I would choose Perl to solve some of the problems. While shell can do some things internally, it is not a full language like Perl or Python, and my style is to use shell to join together lots of other basic tools to get jobs done, not to write whole applications in shell. YMMV.
