This is a really useful well written book - I have it in hardback. Unfortunately the Kindle edition which I just bought is almost unusable. All the coding examples are presented as tiny images, clicking on the image enlarges it but the quality is dreadful and you can then not see the explanatory text. Why do publishers not look at the quality of what they produce before selling it?
Short concise examples that are easy to understand, but probably not for more experienced bash users. I am a beginner and this book suited me down to the ground currently working in IT sector using bash for the first time.
