I bought this as a present for my son who is currently self-studying Ruby. He is delighted and has learned so much from the book to enhance and short cut his learning. Definitely worth buying.

This book is more about Ruby artefact management than enhancing the Unix shell. It's a kind of `Jack of a few trades' in that respect. Which is great if you're a developer that is using or maintaining a basic Ruby development environment. However, I was looking for a tutorial on Ruby Unix shell one-liners that I could use when working in a PuTTY window; one-liners that go beyond grep and sed and the bash shell. In this regard I was disappointed. This book does cover the basics of gems, YAML, CVS and Cucumber, but Python does similar (Lettuce being Python's Cucumber). This book wasn't for me, I returned it. If you are looking for a book on Unix one-liner shell enhancements, look no further than: `Minimal Perl for Unix and Linux people by Tim Maher'. I just wish there was a Ruby version of that Perl book.
