2.4 Naming Standard Input
=========================

Often, you may wish to read standard input together with other files.
For example, you may wish to read one file, read standard input coming
from a pipe, and then read another file.

   The way to name the standard input, with all versions of 'awk', is to
use a single, standalone minus sign or dash, '-'.  For example:

     SOME_COMMAND | awk -f myprog.awk file1 - file2

Here, 'awk' first reads 'file1', then it reads the output of
SOME_COMMAND, and finally it reads 'file2'.

   You may also use '"-"' to name standard input when reading files with
