still it shows lot of lines in diff even when file name/path/size/checksum is same. ...
You may want to list, sort and find cksum of each file as shown in the following example:

Code:
$ # go to directory dir1
$ cd dir1
$
$ ls | sort | xargs cksum
1958180199 14 file1
1994293486 14 file2
1996893289 14 file3
$
$ # now do the same for directory dir2
$ cd ../dir2
$
$ ls | sort | xargs cksum
1958180199 14 file1
1994293486 14 file2
1996893289 14 file3
$
$

And as you are doing currently, redirect the output to two files and find the diff.
