Hi ctruhn, Thank you for replying so quickly. I was afraid that my post is lengthy and confusing.
My goal is to compare 2 different files and show the result side by side in this format:
Desire output of file1 and file2 separated by a tab
---------------
die1
die2 die2
die3
lb_name1 lb_name1
lb_name2 lb_name2
lb_name3
There should be a tab between the 2 column. (This forum will not let me use tabs .. it turns into spaces
). So when we glance at this output, we will quickly see that the differences between the 2 files are die1, die3, and lb_name3. I've been researching in this post and googling for the past week and have not found a solution to this problem.
Please let me know if there is an easier way than what I proposed in my previous post.
Thanks.

comm
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
