One could also try:
Code:
awk 'FNR == 1 { fc++ } fc < 3 {d[$0]; next } !($0 in d)' DIFF MATCH ALL

which has been tested.

This requires enough space for the unique records in DIFF and MATCH to be held in memory, but doesn't require space in memory for the unique records in ALL.

ragator

RAGATOR(1)						      General Commands Manual							RAGATOR(1)

NAME

       ragator - aggregate argus(8) data file entries.

COPYRIGHT

       Copyright (c) 2000-2003 QoSient. All rights reserved.

SYNOPSIS

       ragator [-f ragator.conf] [raoptions]

DESCRIPTION

       Ragator	reads argus(8) data from an argus-file, and merges matching argus flow activity records together.  In its default mode of options,
       this effectively converts argus(8) files from detail to non-detail mode, and merges periodic flow report records to a single argus  record,
       thus compressing the argus(8) file to a reduced size.

       You can modify the aggregation strategy used by ragator to merge records together, by using the -f ragator.conf option.	See ragator(5) for
       a complete description of the format and syntax of the flow model file.

OPTIONS

       Ragator, like all ra based clients, supports a number of ra options including filtering of input argus records through a terminating filter
       expression.  See ra(1) for a complete description of ra options.

AUTHORS
