Compare the checksum of files in 2 different folders

Hi

I have 2 different folders on different machines. they are supposed to be same but some time for unknown reason they are not. then we have to generate a report for files which are not matching.

I was doing as below -

Code:
cd folder1
find . -type f | sort | cksum >1.txt

cd folder2
find . -type f | sort | cksum >2.txt

1)
Code:
diff -w 1.txt 2.txt

still it shows lot of lines in diff even when file name/path/size/checksum is same. is there any nice and clean way to report the expected result.

2) i was able to generate good results (but not good format) by using -
Code:
cat 1.txt 2.txt | sort -k 3,3 | uniq -u

it does not tell me which file is from which folder (there is no < or > sign as we have in diff)

is there any other best way to do it ?

Thanks
Rel
