Features: This book starts with an overview and guide, discussing the continuous improvement of functions from grep to sed to awk. Both sed and awk share the same command-line syntax, accepting user commands in the form of scripts. Since all three programs use UNIX regular expressions, the book dedicates a chapter to introducing the syntax of UNIX regular expressions. Then, the book explains how to write sed scripts. Starting with writing a few simple scripts, you learn other basic and advanced commands for manual editing operations, as well as the simple program structures introduced by them. These advanced commands include those for handling hold spaces, i.e., buffers with equal proportions.
