When processing text files, the awk language is ideal for handling data extraction, reporting, and data-reformatting jobs. This practical guide serves as both a reference and tutorial for POSIX-standard awk and for the GNU implementation, called gawk. This book is useful for novices and awk experts alike. In this thoroughly revised edition, author and gawk lead developer Arnold Robbins describes the awk language and gawk program in detail, shows you how to use awk and gawk for problem solving, and then dives into specific features of gawk. System administrators, programmers, webmasters, and other power users will find everything they need to know about awk and gawk. You will learn how to: Format text and use regular expressions in awk and gawk Process data using awk's operators and built-in functions Manage data relationships using associative arrays Define your own functions "Think in awk" with two full chapters of sample functions and programs Take advantage of gawk's many advanced features Debug awk programs with the gawk built-in debugger Extend gawk by writing new functions in C or C++ This book is published under the terms of the GNU Free Documentation License.

Chromatography - A Century of Discovery 1900-2000 represents the combined thinking and contributions of many chromatographers. It includes several in-depth feature chapters covering the Beginnings of Chromatography, which highlights M.S. Tswett, the inventor of chromatography, and several other early pioneers. Included are the contributions of several Nobel Laureates,and 125 Chromatography Award Winners and contributors, an extensive bibliography of publications on the History of the Evolution of Chromatography; a presentation of Major International Symposia supporting chromatography and as a bridge to selected sciences. Special chapters are written by well-known Chromatographers on Support and Stationary Phases, and Separations followed by a chapter on Milestones and Paradigm Shifts in Science. New discoveries in the life sciences and medicine, agriculture, the environment and separations technology in the 21st century will rely immeasurably on the 20th century research tools in chromatography and those yet to be developed.
