Your calculations seem to assume that there will always be exactly two lines with a given 3rd field value. Are these pairs of lines always adjacent (as in your sample input and output)? Can there be just one or more than two lines with a given 3rd field value (and, if so, should the division be by 2 or by the number of lines with that 3rd field value)?
Quote:
No there will be not exactly two lines with given 3rd field value. It can 1,2 or 3 . Depending on input data.These pairs of lines will always adjacent(because 3rd key column is sorted).
Why are you printing ten fields to your output file when there are only nine input fields? This is adding a trailing space to each line of your output file that is not present in the sample output that you say you want???
Quote:
This 10th value printed by mistake. You can skip that.
Does the width of any of your input columns vary, or are the column widths for each column constant for files this script will process?
Quote:
the width of columns may change. This is the major issue I am facing here.
If you could give the solution for this to be printed dynamically with updated value of column 8 will be very helpful.

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.
ENVIRONMENT
The LANG, LC_ALL, LC_COLLATE, and LC_CTYPE environment variables affect the execution of comm as described in environ(7).
EXIT STATUS
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'').
The -i option is an extension to the POSIX standard.
HISTORY
A comm command appeared in Version 4 AT&T UNIX.
BUGS
Input lines are limited to LINE_MAX (2048) characters in length.
