How to Run `awk' Programs
=========================

   There are several ways to run an `awk' program.  If the program is
short, it is easiest to include it in the command that runs `awk', like
this:

     awk 'PROGRAM' INPUT-FILE1 INPUT-FILE2 ...

where PROGRAM consists of a series of patterns and actions, as
described earlier.

   When the program is long, it is usually more convenient to put it in
a file and run it with a command like this:

     awk -f PROGRAM-FILE INPUT-FILE1 INPUT-FILE2 ...
