Thanks DGPickett. Am notsure what change needs to be done for the above script. I did tried them by changing head1 to oldfile path and head2 newfile path.

Could you please correct me.
Code:
diff -U0 <(
cd /usr/config_check/oldfiles/
find * -type f | sort ) <(
cd /usr/config_check/newfile/
find * -type f | sort ) | while read diff_ind cksum sz path
do
case "$diff_ind" in
(-)
echo "Deleted file '$path'."
;;
(+)
echo "New file '$path':"
cat head2/$path
;;
(*)
echo "Changed file '$path':"
sdiff /usr/config_check/oldfiles/$path /usr/config_check/newfile/$path
;;
esac
done

After running above script, i get this error
Code:
root@att02 # ./cfile.sh
Changed file '':
sdiff: Cannot open: /usr/config_check/oldfiles//newfile/

rredtool

RREDTOOL(1)							     REPREPRO							       RREDTOOL(1)

NAME

       rredtool - merge or apply a very restricted subset of ed patches

SYNOPSIS

       rredtool --help

       rredtool [ options ] --merge patches...

       rredtool [ options ] --patch file-to-patch patches...

       rredtool directory newfile oldfile mode

DESCRIPTION

       rredtool  is  a	tool to handle a subset of ed patches in a safe way.  It is especially targeted at ed patches as used in Packages.diff and
       Sources.diff.  Is also has a mode supposed to be called from reprepro as Index Hook to generate and update a Packages.diff/Index file.

MODI

       One of the following has to be given, so that rredtool know that to do.

       --version
	      Print the version of this tool (or rather the version of reprepro which it is coming with).

       --help Print a short overview of the modi.

       --patch
	      The first argument of rredtool is the file to patch, the other arguments are ed patches to apply on this one.

       --merge
	      The arguments are treated as ed patches, which are merged into a single one.

       --reprepro-hook (or no other mode flag)
	      Act as reprepro index hook to manage a Packages.diff/index file.	That means it expects to get exactly 4 arguments  and  writes  the
	      names of files to place into filedescriptor 3.

	      If neither --patch nor --merge is given, this mode is used, so you can just put

	       DebIndices: Packages Release . .gz /usr/bin/rredtool

	      into  reprepro's	conf/distributions  file  to  have a Packages.diff directory generated.  (Note that you have to generate an uncom-
	      pressed file (the single dot).  You will need to have patch, gzip and gunzip available in your path.)

OPTIONS

       --debug
	      Print intermediate results or other details that might be interesting when trying to track down bugs in rredtool but not	intresting
	      otherwise.

       --max-patch-count=count
	      When generating a Packages.diff/Index file, put at most count patches in it (not counting possible apt workaround patches).

       -o|--output
	      Not yet implemented.

ENVIRONMENT

       TMPDIR, TEMPDIR
	      temporary files are created in $TEMPDIR if set, otherwise in $TMPDIR if set, otherwise in /tmp/.
