I much appreciate the author's efforts in writing such a wonderfull program but speaking about the book... I found it to be a bit hard to follow. The systemization in introducing this technology leaves much to be desired.
Most of the O'Reilly books you can literally can start reading and actually using them without of any prior experience in whatever the subject is, unfortunately it does not apply to the Exploring Expect book.
For example right now I need to find out how to programm cursor movemets via expect in order to navigate menu driven telnet interface, and quess what - the only mentioning of the arrows is on page 286, which asks me to write code, which will do it. SO I an surfing the WWW for the answer. I would think that would be quite common question, but for some reason it is not answered in the book.
Having said all above it is still a-must-to-have for any unix sysadmin it's O'Reilly book after all.
