1. Introduction


Awk is a programming language designed to make many

common information retrieval and text manipulation tasks

easy to state and to perform.


The basic operation of awk is to scan a set of input

lines in order, searching for lines which match any of a set

of patterns which the user has specified. For each pattern,

an action can be specified; this action will be performed on

each line that matches the pattern.
