Just like all this author's Beginner's Guides, information that should fill no more than 3 pages of A4, was churned into a guide book. He even presumes to add his fictional ramblings as if that ameliorates the original insult of the poor standard of the guide. Why anyone would want to read his stories when his technical nous is limited, is beyond me. There is nothing he offers about the Linux command line that cannot be found on-line anyway. Anyone wishing to read about an Operating System's Command line surely has no interest to read stories. Ridiculous.
