This tutorial teaches users how to work with the features and facilities of the Bourne Shell and helps them gain a clear understanding of the Shell's capabilities for programming.
So I was given this book by my dad who learned the basics of shell scripting back in the 90s when he first started learning about computers. He has been working in the industry for around 24 years now and says this was the very start.
I think the book overall is very descriptive. There are many explanations and multiple ways given to solve a given problem. It would be good for anyone trying to learn the basics so they can understand shell scripts when they read them.
Although it is very descriptive, there are so many isolated examples that it makes it difficult for a beginner to apply the principles into a real script.
Another thing I wish the book would do is be consistent in assumption of knowledge. Some sections seem to be written for a 3rd grader while others seem to be written for someone who already has industry experience.
