The title here is appropriate, the only point where I question the content is in the last three sections. The titles are:
*) Tutorial: Programming in C
*) Tutorial: Programming in C++
*) Tutorial: Programming in Java
All three are a maximum of 15 pages long, not enough coverage to provide any worthwhile information. It would have made more sense to do a bit more UNIX.
The remaining material is typical of an introductory course in UNIX and is very understandable, the level is such that the book could be used in a community education course in UNIX. If a position requires some work using UNIX and a new hire has no experience in UNIX but is computer savvy, all you would need to do is hand them this book and turn them loose. A short series of basic exercises appears at the end of each chapter, no solutions are given.
If you have a need for a quick and understandable tutorial on the basics of UNIX on the command line, this book will work well for you.
