Lions’ Commentary on UNIX 6th Edition with Source Code by John LionsThis legendary underground classic, reproduced without modification, is really two works in one:
?? the complete source code to an early version of the UNIX operating system; and
?? a brilliant commentary on that code by John Lions
Dennis Ritchie, Ken Thompson, and other UNIX luminaries have contributed new essays on the enduring value of this Computer Science masterpiece.
Lions’ marriage of source code with commentary was originally used as an operating systems textbook, a purpose for which it remains well-suited. As a self-study UNIX conceptual tutorial, it has informed and inspired computer professionals and advanced operating system students for over twenty years.
Lions’ Commentary on UNIX 6th Edition with Source Code
I consider this to be the single most important book of It shows how UNIX was ported not only to machines which were scarce but also to the minds of young researchers and student programmers which were plentiful. Several generations of both academic computer scientists and students who went on to work for computer or software corporations were trained on photocopies of UNIX source code, with a whiff of toner and illicit circulation: a distributed operating system in the textual sense. The one big chunk of code available then was UNIX, but even this was not open source. Both individuals and bookstores can also order copies from our fulfillment agent Lulu.

It is commonly referred to as the Lions Book. Despite its age, it is still considered an excellent commentary on simple but high quality code. John Lions was an Australian computer scientist. In computing, source code is any collection of code, possibly with comments, written using a human-readable programming language, usually as plain text. The source code of a program is specially designed to facilitate the work of computer programmers, who specify the actions to be performed by a computer mostly by writing source code. The source code is often transformed by an assembler or compiler into binary machine code understood by the computer.

It is commonly referred to as the Lions Book. Despite its age, it is still considered an excellent commentary on simple but high quality code. For many years, the Lions book was the only Unix kernel documentation available outside Bell Labs. Although the license of 6th Edition allowed classroom use of the source code, the license of 7th Edition specifically excluded such use, so the book spread through illegal copy machine reproductions a kind of samizdat. It was commonly held to be the most copied book in computer science. All procedures and symbols are listed alphabetically with a cross reference.
Social Problem in Enterprise Unix Administration. The Peter Principle. Nineteen Eighty-Four. The Good Soldier Svejk. The two parts of this book contained 1 the entire source listing of the Unix Version 6 kernel, and 2 a commentary on the source discussing the algorithms. Because Western Electric wished to maintain trade secret status on the kernel, the Lions Book was only supposed to be distributed to affiliates of source licensees.
