This book introduces the concepts and features of Linux. It describes the features and services of the Internet which have been instrumental in the rapid development and wide distribution of Linux and focuses on the graphical interface, network capability, and extended tools of Linux. It also gives an overview of the wide range of freeware applications available for Linux. Now completely revised and expanded to help the reader take full advantage of the high-performance of Linux 2.0, this third edition lists all of the currently supported hardware; provides the latest information on Linux as client/server; explains the newest applications including StarOffice 3.1, new graphics tools (including GIMP), Xemacs, and LyX; and presents the most up to date information on security and cryptography. Plus, there is a new UNIX command reference with entries grouped by purpose, as well as a new section on how to deal with errors. All in all, the most up-to-date information on Linux available!NIX achieved its widespread propagation, its penetration of UNIX history U the university domain, and its reach into research and industry due to its early dissemination by AT&T to all interested parties at almost no cost and as source code. UNIX's present functionality emanated not just from AT&T developers but also from many external developers who used the product and contributed their own further developments, which they then put at AT&T's disposal. (Consider the contributions of the University of California at Berkeley, for example.) With the rising commercialization of UNIX by AT&T (and the current owner, Novell) since 1983, and with the philosophical wars between the large UNIX vendors such as Sun, HP, Digital, IBM, SCQ, and the UNIX laboratory, as well the more rhetorical than factual discussions between QSF and UNIX International, such creative and cooperative continuing development became increasingly restricted, and UNIX source code today has become unaffordably eló#
