Compare two files and do...

hi people;
i have two texts:

file.txt:
Code:
cell137 1
cell337 1
cell355 1
cell355 2
cell355 3
cell360 1
cell360 2
cell360 3
...

file-new.txt:
Code:
cell137 1
cell355 1
cell355 2
cell355 3
cell360 1
cell360 2
cell370 3
...

the script will compare two files and;

- if the same entry exists in both files, write 'zero' to a third file zero.txt.
- if the entry in file.txt doesnot exist in file-new.txt, write that entry to a third file: back.txt.
- if there is a new entry in file-new.txt, write that entry to a third file: new.txt.

i have tried;
Code:
comm /gc_sw/file.txt /gc_sw/file-new.txt

and the output is:
Code:
                cell137 1
cell337 1
                cell355 1
                cell355 2
                cell355 3
                cell360 1
                cell360 2
cell360 3
        cell370 3

but i couldn't process it! Smilie
