gawk: Patterns and Actions

 
 7 Patterns, Actions, and Variables
 **********************************
 
 As you have already seen, each 'awk' statement consists of a pattern
 with an associated action.  This major node describes how you build
 patterns and actions, what kinds of things you can do within actions,
 and 'awk''s predefined variables.
 
    The pattern-action rules and the statements available for use within
 actions form the core of 'awk' programming.  In a sense, everything
 covered up to here has been the foundation that programs are built on
 top of.  Now it's time to start building something useful.
