A comprehensive guide to the text editing, formatting, and document preparation tools with the UNIX operating system, from the author of the widely-used The UNIX Operating system. The first chapter acts as a guide to the material in the succeeding 11 chapters. Goes on to cover the UNIX system's most popular text editor: vi; how vi can be retrofitted as a rudimentary word processor for simple jobs; the standard formatters nroff and troff; and the two most popular macro packages, -ms and -mm. Also discusses eqn (the first preprocessor), an aid for typesetting mathematics; The tbl preprocessor, for typesetting tables; refer, an aid for typesetting and managing references. The UNIX system's latest preprocessor, pic, an aid for typesetting line drawings, is also explored, as well as various standard UNIX utility programs that aid document preparation.

GNU Emacs is the most popular and widespread of the Emacs family of editors. It is also the most powerful and flexible. Unlike all other text editors, GNU Emacs is a complete working environment -- you can stay within Emacs all day without leaving. The GNU Emacs Pocket Reference is a companion volume to O'Reilly's Learning GNU Emacs, which tells you how to get started with the GNU Emacs editor and, as you become more proficient, it will help you learn how to use Emacs more effectively.This small book, covering Emacs version 20, is a handy reference guide to the basic elements of this powerful editor, presenting the Emacs commands in an easy-to-use tabular format.

-Teaches the reader how to use Unix, which is the key to basic computing and allows the most flexibility for bioinformatics applications -Written specifically with the needs of molecular biologists in mind -Easy to follow, written for beginners with no computational knowledge -Includes examples from biological data analysis -Can be use either for self-teaching or in courses

If you need to parse or process text data in Linux or Unix, this useful book explains how to use flex and bison to solve your problems quickly. flex & bison is the long-awaited sequel to the classic O'Reilly book, lex & yacc. In the nearly two decades since the original book was published, the flex and bison utilities have proven to be more reliable and more powerful than the original Unix tools. flex & bison covers the same core functionality vital to Linux and Unix program development, along with several important new topics. You'll find revised tutorials for novices and references for advanced users, as well as an explanation of each utility's basic usage and simple, standalone applications you can create with them. With flex & bison, you'll discover the wide range of uses these flexible tools offer. Address syntax crunching that regular expressions tools can't handle Build compilers and interpreters, and handle a wide range of text processing functions Interpret code, configuration files, or any other structured format Learn key programming techniques, including abstract syntax trees and symbol tables Implement a full SQL grammar-with complete sample code Use new features such as pure (reentrant) lexers and parsers, powerful GLR parsers, and interfaces to C++

Shell scripting skills never go out of style. It's the shell that unlocks the real potential of Unix. Shell scripting is essential for Unix users and system administrators-a way to quickly harness and customize the full power of any Unix system. With shell scripts, you can combine the fundamental Unix text and file processing commands to crunch data and automate repetitive tasks. But beneath this simple promise lies a treacherous ocean of variations in Unix commands and standards. Classic Shell Scripting is written to help you reliably navigate these tricky waters.Writing shell scripts requires more than just a knowledge of the shell language, it also requires familiarity with the individual Unix programs: why each one is there, how to use them by themselves, and in combination with the other programs. The authors are intimately familiar with the tips and tricks that can be used to create excellent scripts, as well as the traps that can make your best effort a bad shell script. With Classic Shell Scripting you'll avoid hours of wasted effort. You'll learn not only write useful shell scripts, but how to do it properly and portably.The ability to program and customize the shell quickly, reliably, and portably to get the best out of any individual system is an important skill for anyone operating and maintaining Unix or Linux systems. Classic Shell Scripting gives you everything you need to master these essential skills.

In Sed & Awk, Dale Dougherty and Arnold Robbins describe two text manipulation programs that are mainstays of the UNIX programmer's toolbox. This new edition covers the Sed and Awk systems as they are now mandated by the POSIX standard.
