“A quick reference book at an affordable price, that is both
well laid out and sufficiently detailed.”
“This book won’t teach you Linux – it is a quick reference,
after all – but it will prove useful to both the beginner and the
advanced user.“
“The second chapter, which runs to about 160 pages and equals
about a third of the book, contains a detailed table that lists all
the Linux user commands – the ones that aren’t part of specific
shells, programming languages, applications, or the set of
administrator commands – and their switches, with descriptions
listed alphabetically.”
