Présentation de l'éditeur
For people who create and modify text files, sed and awk are power tools for editing. sed, awk, and regular expressions allow programmers and system administrators to automate editing tasks that need to be performed on one or more files, to simplify the task of performing the same edits on multiple files, and to write conversion programs.The sed & awk Pocket Reference is a companion volume to sed & awk, Second Edition, Unix in a Nutshell, Third Edition, and Effective awk Programming, Third Edition. This new edition has expanded coverage of gawk (GNU awk), and includes sections on:
- An overview of sed and awk?s command line syntax
- Alphabetical summaries of commands, including nawk and gawk
- Profiling with pgawk
- Coprocesses and sockets with gawk
- Internationalization with gawk
- A listing of resources for sed and awk users
This small book is a handy reference guide to the information presented in the larger volumes. It presents a concise summary of regular expressions and pattern matching, and summaries of sed and awk.Arnold Robbins, an Atlanta native now happily living in Israel, is a professional programmer and technical author and coauthor of various O'Reilly Unix titles. He has been working with Unix systems since 1980, and currently maintains gawk and its documentation.
sed & awk
describes two text processing programs that are mainstays of the UNIX programmer's toolbox. The book lays a foundation for both programs by describing how they are used and by introducing the fundamental concepts of regular expressions and text matching. This edition covers the sed
programs as they are mandated by the POSIX standard. It also includes a discussion of the GNU versions of both programs, which have extensions beyond their UNIX counterparts. Many examples are used throughout the book to illustrate the concepts discussed.
