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 ...

   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 ...

   This minor node discusses both mechanisms, along with several
variations of each.

One-shot

Running a short throw-away `awk'

program.

Read Terminal

Using no input files (input from terminal

instead).

Long

Putting permanent `awk' programs in

files.

Executable Scripts

Making self-contained `awk' programs.

Comments

Adding documentation to `gawk'

programs.

Quoting
