Linux and the Unix Philosophy

limbo_14 writes "Mike Gancarz takes his oft'-quoted original book, The Unix Philosophy and spruces it up for the Brave New World of Linux with Linux and the Unix Philosophy. Since The Unix Philosophy was written, Unix has undergone many changes and evolutions. Now with Linux emerging as the new face of Unix, he has updated his book with the same philosophy and tenets that were in the first, but updated the book to include considerations for the Open Source community and the new world of Operating Systems in which we live." Even the old version of The Unix Philosophy is worth finding; it may remind you of Neil Stephenson's In the Beginning Was the Command Line. Read on for the rest of limbo_14's review. Linux and the Unix Philosophy author Mike Gancarz pages 200 publisher Butterworth-Heinemann rating Recommended reviewer limbo_14 ISBN 1555582737 summary An updated and expanded version of Gancarz's original book, The Unix Philosophy.

The good stuff... I enjoyed Mike Gancarz' first book The Unix Philosophy greatly when I was first getting into the Unix world, and was hoping for an updated version. The thing that makes this book stand out in the shelves full of How-To, Dummy, and Administrator guides is the fact that it covers the What and Why of Unix/Linux rather than the How's. I am constantly amazed at Unix books that are mostly printed man files, and things that can easily be googled. This book explains with great precision why Unix is the way it is, and what separates it from other OS paradigms.

I realized the importance of this book after reading it, and being forced to do interviews for a Unix Engineer at my office. Of the 7 candidates, 6 of them seemed to know the textbook stuff. They knew the commands, they knew vi and a handful of scripting languages to a degree of proficiency. Alas, this is what it takes to become a Unix Administrator, not an Engineer that needs to see the whole picture. In this world of "puppy mill" Unix admins who have certifications and know one or two flavors of Unix/Linux, this book really teaches people the core of why Unix/Linux is the way it is, and why it is so attractive to those who really care about which OS to use.

The last chapter -- "Brave New (Unix) World)" -- is the real kicker. Gancarz really drives it home, and shows how the Unix/Linux philosophy has made it into other aspects of technology, and in the world we live in.

The not-so-good stuff ... With every good book, there must be some bad, although this one's errors are quite forgivable. Although I appreciate any book that loosens the RFC style nature of so many technical books, sometimes it can go a little too far. This, however, is for each reader to judge. Some of the puns made me squirm, but for the most part they added a nice touch of levity to the book. So, depending on your threshold for python-esque puns or corny Elvis jokes, the book may not be for you, but knowing the /. Crowd, I don't think it will cause anything more than some groans and giggles. All in All... This is a quality book. It is one that should be re-read every now and then to make sure you do not stray from the Tenets that Gancarz drives home throughout the book via anecdotal evidence.This book can and should be read by anyone from a newbie hacker to a Corporate CEO. It is just technical enough not to make one feel patronized, and eases you into it with general concepts just enough to make it not feel like reading IETF standards. Here are the chapters, which give a good overview of what each is about:

• Table of Contents
• The Unix Philosophy: A Cast of Thousand
• One Small Step for Humankind
• Rapid Prototyping for Fun and Profit
• The Portability Priority
• Now THAT'S Leverage!
• The Perils of Interactive Programs
• More Unix Philosophy: Ten Lesser Tenets
• Making Unix Do One Thing Well
• Unix and Other Operating System Philosophies
• Through the Glass Darkly: Linux vs. Windows
• A Cathedral? How Bizarre!
• Brave New (Unix) World

Although this is not the cheapest book in the rack, it packs more of a punch than half of the books on my shelf, so I think it is worth it. I found it a great read on the metro on the way to work in the morning, and found myself finishing it well within a week. With 200 pages, and by making it fun to read, Linux and the Unix Philosophy breezes by and makes for a great read.

Something I've never been able to figure out.

[Anonymous Coward]

Some of the major tenets of the original UNIX philosophy were:

- Small is beautiful.

- Make each program do one thing well.

Why is it then that there are people out there who spend their entire lives with UNIX/Linux, and who ignore this?

Some of the best examples are sendmail and emacs. And no, this isn't a troll. But I just don't understand why such people just don't get it. Clearly it isn't a lack of intelligence.

But this paradox is something which I've never been able to figure out.

The Unix Philosophy

[cperciva]

The Unix Philosophy can be stated in several ways:

"Small interconnecting components"
"Never use one program where you could use several"
"Plumbing is good"

If is a continual source of amazement to me that GNU tools (eg, tar -AcdrtuxbBCfFGhijykKlLmMnNoOpPRsSTIUvVwWXZz7) are widely used despite this.

UNIX = Commercial way of thinking

The UNIX philosophy has nothing to do with commercial vs Free, or closed vs open and has everything to do with design and problem solving. The comercial aspects of UNIX culture were imposed upon UNIX by shareholders and corporations with little or no regard for who had designed the product, whether they had been compensated, or how future maintainance and development would be accomplished. The development of the EMACS editor, the GNU project, and the GPL license were a reaction to these changes in UNIX development. The GPL was not created as an economic "weapon", nor was it created with money in mind at all. It was motivated by a desire to have the source code available to anybody with an idea and the know-how to implement it.

Many posters here seem to be obsessed with money, and it can't be good for thier thinking. Whether they are dogmatic about giving away for free or about charging for every last thought, it betrays an unwillingness to view subjects and viewpoints as other than economically based. I admit that the economics of software development need be considered in any project, but my opinion is that making design decisions based on monetary arguments is putting the cart before the horse and will often result in poorly designed and inferior software.

The UNIX philosophy is not incompatible with the GPL, nor is it incompatible with comercial licensing In fact, the GPL has very little to do wih money in any way whatsoever. In other words, read the book, come back and discuss philosophy when you're prepared.
