Reader Testimonials
James Tomasino
VP, Regional Technology Director, CSM at GSW Worldwide
This book is fantastic. Follow the instructions and actually enter all the commands as they happen. Digging into seemingly simple questions really helped me grok everything. I think I'll give one more read to the section on traps, but otherwise I feel so much stronger in my BASH-FU. Do you work in the terminal? Do yourself a favor and read this.

This book has been so valuable to me. I have used bash as needed for a couple years in bit of a haphazard, "just find things that work type way"(not something I am proud of but just being honest). This book provides a great framework for really understanding the topics covered. I do not come from a CS background in school so books like this are what makes it possible for me to do the work I love.
