I had to do some text processing and I wanted to learn sed & awk so I picked this book that is, to my knowledge, the only book completely dedicated to these tools. The chapter on 'advanced' sed programming is very scary because when using 'advanced' sed features, the syntax is cryptic. It is nice to know that these features are there but I want to stay away from them and perhaps use awk or perl for the tasks that would require those 'advanced' features. Still, when you stick with the 'basic' and 'intermediate' sed features, you can do cool things easily in shell scripts.

Overall, the book was not thrilling to read but it does a good job to teach you these text processing tools.
