I have a similar, but not identical problem.

I have data like this:
It's sorted by the 2nd field (TID).

I want to do the following:
Check the second field to see if the TID is the same as the previous line. If the TID has been seen before then check the 7th field to see if that is the same as the previous line. If both are the same, I want to remove the line and increment a counter.

My ideal output would look something like this.
11,envoy,90000000000000634600010001,04/11/2008,23:19:27,RB00266,0015,DETAIL,ERROR,

etc.

I figure I actually need to do an awk script rather than a 1 liner. The other option is for the last 3 fields to be one field and compare by the TID field and the error field, then split them into 3 on the output.

Any thoughts? I've looked at other stuff removing dups with awk and it's mostly one liners.

I'd love to ask get some explanation of WHY it works so that I can mod it if need be.

gpg-error-config

LIBGPG-ERROR(1) 					      General Commands Manual						   LIBGPG-ERROR(1)

NAME

       libgpg-error-config - script to get information about the installed version of libgpg-error

SYNOPSIS

       libgpg-error-config [--prefix[=DIR]] [--exec-prefix[=DIR]] [--version] [--libs] [--cflags]

DESCRIPTION

       libgpg-error-config  is a tool that is used to configure to determine the compiler and linker flags that should be used to compile and link
       programs that use libgpg-error. It is also used internally to the .m4 macros for GNU autoconf that are included with libgpg-error.

OPTIONS

       libgpg-error-config accepts the following options:

       --version
	       Print the currently installed version of libgpg-error on the standard output.

       --libs  Print the linker flags that are necessary to link a libgpg-error program.

       --cflags
	       Print the compiler flags that are necessary to compile a libgpg-error program.

       --prefix=PREFIX
	       If specified, use PREFIX instead of the installation prefix that libgpg-error was built with when  computing  the  output  for  the
	       --cflags  and  --libs options. This option is also used for the exec prefix if --exec-prefix was not specified. This option must be
	       specified before any --libs or --cflags options.

       --exec-prefix=PREFIX
	       If specified, use PREFIX instead of the installation exec prefix that libgpg-error was built with when computing the output for the
	       --cflags and --libs options.  This option must be specified before any --libs or --cflags options.
