Wow that works great. Looks like I need to read up some more on nawk.

One thing though. This is eliminating the rows from FileA that have the same A3 value but the unique A1. In other words, the merged file should contain 1 row for every A1 field that contains an A3 (no matter if its the same as the one above it). This is eliminating the first 2 lines that have a "DDDD" in FileA. There needs to be 3 lines that have a "DDDD" in the merged output since FileA had 3 different A1's with the same A3. "HHHH" is the same way.

How would you alter this to allow those scenarios to be caught?


:::::::::
::FileA::
:::::::::
A1-------A2--------A3---A4---A5--
=================================
DC35S51--XXXXY1----DDDD------44X-
DC35S52--XXXXY2----DDDD------44Y-
DC35S53--XXXXY3----DDDD------44Z-
=================================

:::::::::
::FileB::
:::::::::
B1------B2-------------------B3--------B4--------B5----------
=============================================================
DDDD----+NDMMN.BMXXMNX-------27/98B----NX/778----93010-------
=============================================================

It should come out to this:

:::::::::::::::
::Merged File::
:::::::::::::::
A1--------A3----B2----------------B3------B4------B5------
==========================================================
DC35S51---DDDD--+NDMMN.BMXXMNX----27/98B--NX/778--93010---
DC35S52---DDDD--+NDMMN.BMXXMNX----27/98B--NX/778--93010---
DC35S53---DDDD--+NDMMN.BMXXMNX----27/98B--NX/778--93010---
==========================================================

But instead its coming out like this:

A1--------A3----B2----------------B3------B4------B5------
==========================================================
DC35S53---DDDD--+NDMMN.BMXXMNX----27/98B--NX/778--93010---
==========================================================

eliminating the DC35S51 & DC35S52.

vconsole.conf

VCONSOLE.CONF(5)                                                   vconsole.conf                                                  VCONSOLE.CONF(5)

NAME

       vconsole.conf - configuration file for the virtual console

SYNOPSIS

       /etc/vconsole.conf

DESCRIPTION

       The /etc/vconsole.conf file configures the virtual console, i.e. keyboard mapping and console font.

       The basic file format of the vconsole.conf is a newline-separated list environment-like shell-compatible variable assignments. It is
       possible to source the configuration from shell scripts, however, beyond mere variable assignments no shell features are supported,
       allowing applications to read the file without implementing a shell compatible execution engine.

       Note that the kernel command line options vconsole.keymap=, vconsole.keymap.toggle=, vconsole.font=, vconsole.font.map=,
       vconsole.font.unimap= may be used to override the console settings at boot.

       Depending on the operating system other configuration files might be checked for configuration of the virtual console as well, however only
       as fallback.

OPTIONS

       The following options are understood:

       KEYMAP=, KEYMAP_TOGGLE=
           Configures the key mapping table of for they keyboard.  KEYMAP= defaults to us if not set. The KEYMAP_TOGGLE= can be used to configured
           a second toggle keymap and is by default unset.

       FONT=, FONT_MAP=, FONT_UNIMAP=
           Configures the console font, the console map and the unicode font map.  FONT= defaults to latarcyrheb-sun16.

EXAMPLE

       Example 1. German keyboard and console

       /etc/vconsole.conf:

           KEYMAP=de-latin1
           FONT=latarcyrheb-sun16
