Use the unique option of the sort command.
Sort the file using the unique option. Then use diff between the original and the output (of the sort) file. Then use the diff file to remove the records from the output file of the sort.

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
