I'll repeat the request of our Forum Advisor drl:

Quote:
To obtain the best answers quickly when you want help in
processing datasets -- extracting, transforming, filtering,
then:

1. Post representative samples of your data (i.e. data that
should "succeed" and data that should "fail")

2. Post what you expect the results to be, instead of trying
only to describe them.

3. Post what you have attempted to do so far.

4. Place the data within CODE tags, so that it more easily
readable.

Special cases, exceptions, etc., are very important to include
in the samples.

COMM(1) 						    BSD General Commands Manual 						   COMM(1)

NAME
comm -- select or reject lines common to two files SYNOPSIS
comm [-123i] file1 file2 DESCRIPTION
The comm utility reads file1 and file2, which should be sorted lexically, and produces three text columns as output: lines only in file1; lines only in file2; and lines in both files. The filename ``-'' means the standard input. The following options are available: -1 Suppress printing of column 1. -2 Suppress printing of column 2. -3 Suppress printing of column 3. -i Case insensitive comparison of lines. Each column will have a number of tab characters prepended to it equal to the number of lower numbered columns that are being printed. For example, if column number two is being suppressed, lines printed in column number one will not have any tabs preceding them, and lines printed in column number three will have one. The comm utility assumes that the files are lexically sorted; all characters participate in line comparisons. DIAGNOSTICS
The comm utility exits 0 on success, and >0 if an error occurs. SEE ALSO
cmp(1), diff(1), sort(1), uniq(1) STANDARDS
The comm utility conforms to IEEE Std 1003.2-1992 (``POSIX.2''). HISTORY
A comm command appeared in Version 4 AT&T UNIX. BSD
June 6, 1993 BSD
