I have modified the command as suggested by you. Now I am getting 00000000 for those lines for which third column is empty. But still the lines unique in file 2 are not getting displayed in merged file.
Try this
Code:
awk 'NR==FNR{a[$1]=$2;next;}{print $1, $2, ( ($1 in a) ? a[$1] : "00000000"); delete a[$1] }END{for(i in a)print i,a[i],"not-exists-in-file1"}' file2 file1

merge
merge(1) General Commands Manual merge(1)NAME
merge - three-way file merge
SYNOPSIS
file1 file2 file3
DESCRIPTION
combines two files that are revisions of a single original file. The original file is file2, and the revised files are file1 and file3.
identifies all changes that lead from file2 to file3 and from file2 to file1, then deposits the merged text into file1. If the option is
used, the result goes to standard output instead of file1.
An overlap occurs if both file1 and file3 have changes in the same place. prints how many overlaps occurred, and includes both alterna-
tives in the result. The alternatives are delimited as follows:
lines in file1
lines in file3
If there are overlaps, edit the result in file1 and delete one of the alternatives.
This command is particularly useful for revision control, especially if file1 and file3 are the ends of two branches that have file2 as a
common ancestor.
EXAMPLES
A typical use for is as follows:
1. To merge an RCS branch into the trunk, first check out the three different versions from RCS (see co(1)) and rename them for
their revision numbers: 5.2, 5.11, and 5.2.3.3. File 5.2.3.3 is the end of an RCS branch that split off the trunk at file 5.2.
2. For this example, assume file 5.11 is the latest version on the trunk, and is also a revision of the "original" file, 5.2.
Merge the branch into the trunk with the command:
3. File 5.11 now contains all changes made on the branch and the trunk, and has markings in the file to show all overlapping
changes.
4. Edit file 5.11 to correct the overlaps, then use the command to check the file back in (see ci(1)).
