hi yogesh diff is NOT solving the problem ( i have tried that)..
bcoz the output apart from giving the difference in file contents is also displaying line numbers and other special kind of instructions ...
we got to pick up only the modified data from this third file .. so diff doesn't work out here properly
for eg below is one such display
1c1,2
< 1|2|2|2|4|3

> 1|2|3|2|3|4

zdiff
ZDIFF(1) General Commands Manual ZDIFF(1) NAME
zcmp, zdiff - compare compressed files SYNOPSIS
zcmp [ cmp_options ] file1 [ file2 ] zdiff [ diff_options ] file1 [ file2 ] DESCRIPTION
Zcmp and zdiff are used to invoke the cmp or the diff program on files compressed via gzip. All options specified are passed directly to cmp or diff. If only file1 is specified, it is compared to the uncompressed contents of file1.gz. If two files are specified, their con- tents (uncompressed if necessary) are fed to cmp or diff. The input files are not modified. The exit status from cmp or diff is pre- served. SEE ALSO
cmp(1), diff(1), zmore(1), zgrep(1), znew(1), zforce(1), gzip(1), gzexe(1) BUGS
Messages from the cmp or diff programs may refer to file names such as "-" instead of to the file names specified. ZDIFF(1)
