sed & awk-轻识

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 and awk 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.
