Batch script to return contrast text between two files

I need to write a batch file which can return the c开发者_如何学Pythonontrasted text between two csv files. So for instance if file1.csv has:

"a,b,c,d,e,f,g,h"

and file2.csv has:

"a,b,c,d,e"

I need to return:

",f,g,h" 

and save it to a new file.

I've tried using the COMP and DIFF (GNU DiffUtils) commands, but haven't been able to get the simple output format I need. I only need the contrasted data between the two files. Does anyone know of a free tool I can use for this?

Many thanks,

-Will

Would this be enough for you?

cat file1.csv | cut -d, -f6-

(How would the content of file2.csv need to be of influence?)

e.g.

echo "a,b,c,d,e,f,g,h"  | cut -d, -f6-
f,g,h

Edit additionally, there is http://os.ghalkes.nl/dwdiff.html This will result in quite different output formats though
