UNIX

The first edition of this book was originally published in 1993 by John Wiley under the same name, Advanced Topics in UNIX. It was named an Alternate Main Selection of the Newbridge Book Club in the same year. That book stayed in print for thirteen years, an eternity in the computing literature. Due to changes in the publishing industry, this edition of the book is only available electronically. I was motivated to revise the book because of the increased popularity of several variants of UNIX and on what I learned from reviews of the previous published version of this book. Linux has become increasingly popular, due in no little part to it being so popular in the open source community and also because it is serving as the basis of the operating system for the Google Android phone. The Mach operating system, originally developed at Carnegie Mellon University, is the basis for the operating systems used to control Apple Macintosh computers. Solaris, originally developed by Sun Microsystems, is now considered by Oracle to be the top enterprise operating system and also claimed to have been especially built for cloud computing. It was clear to me that a revision of the book was necessary. I am currently running versions of both Linux (Ubuntu) and Solaris on my Windows PC. Of course, the operating system on my Macintosh is based on Mach. My experience with multiple versions of UNIX-like operating systems showed me that end users, application programmers, system programmers, and system administrators often had difficulties in making programs and utilities work well across different UNIX variants, due to differences in file system organization, different locations of critical configuration files, and important, yet subtle, differences in how system calls operate. There are also issues with different utilities, many of which are either not available on all UNIX versions, or else require a substantial effort to even get them to install properly. One of the most interesting problems required detailed analysis of several Linux variants in order to get a single public domain application to work - the different Linux variants from Fedora (formerly Red Hat), SUSE, and Ubuntu were examined before the application would install and work properly. Many second editions dump material from older technologies. I have chosen a different approach, guided by my own research and experience in the efficient development of large, high-quality, software systems in both UNIX and non-UNIX environments over much of the last twenty-five years. Much of my research in this area is based on the application of systematic approaches to software reuse as part of the software development process. In fact, I chose to produce a second edition of my book Software Reuse: Methods, Models, Costs before I began revising this book, Advanced Topics in UNIX. What is the relevance of software reuse to a book on UNIX? A huge percentage of current software applications for UNIX and other operating systems are built using existing software components that are either partially or entirely reused. Older software components necessarily have been built using older technology and are likely to use some of the older system calls as well as newly created calls. You need to understand the differences in different generations of system calls and their behavior if you are redeploying existing software components. That is, after all, the reason for learning system calls if you are an applications programmer. The same holds true for systems-level programming, especially kernel-level programming, since operating systems are rarely written from scratch. There are 11 chapters: Introduction to UNIX, The User Interface, Input and Output, UNIX File Systems, Introduction to Processes, Memory and Process Management, Introduction to Interprocess Communication, The System V IPC Package, Signals, Sockets, and RPC, IPC Comparison, and Fault-Tolerant UNIX Software.

Ronald J. Leach recently retired as Professor and Chair Emeritus from the Department of Systems and Computer Science at Howard University, where he had taught since 1969. He received the B.S., M.S., and Ph.D. degrees from the University of Maryland at College Park and the M. S. degree in Computer Science from Johns Hopkins University. His research interests include distributed systems, performance modeling and capacity planning; and most areas of software engineering, especially software reuse, fault-tolerance, and software performance measurement and their empirical foundations. Some of his current work includes the application of computing to the social sciences, especially in the area of name matching within historical documents, using both his computer search skills and genealogical knowledge. He is a frequent member of ABET site visit teams. He is an experienced cruise ship lecturer, with special emphasis on identity theft and computer forensics. He also lectures to other groups. Ron Leach is the author of seven print books: Using C in Software Design, Academic Press Professional, Advanced Topics in UNIX, John Wiley; Object-Oriented Design and Programming in C]+, Academic Press Professional, Software Reuse: Methods, Models, and Costs, McGraw-Hill, Introduction to Software Engineering, CRC Press, Genealogy for the Information Age, Disruptive Publishing, and Relative Genealogy, Disruptive Publishing. He has published two books on the subject of identity theft: Twelve and a Half Steps to Avoid Identity Theft, as an ebook, and Identity Theft in the Cyber Age, which is available as both an ebook and in print. Revised editions of many of these are available as ebooks. Dr. Leach has offered technical training and seminars on software reuse, reengineering, and testing on three continents. He has lectured on a variety of other topics between continents! He is also the author or co-author of more than one hundred technical papers. In his spare time, he is the co-Editor of the Maryland Genealogical Society Journal and is webmaster for its newly designed website.
