how to diff and show only exact differences for 2 long string

Question

I have 2 files- a and b.

a

1,"abc","( @docid =""00123"" or @docid =""00456"") AND a_number is not NULL"

1,"abc","( @docid =""00123"" or @docid =""00456"") AND @a_number is not NULL"

How do I diff this 2 files and show only the part changes in a_number instead of the whole string?

I like to use

$ wdiff a b

# 1,"abc","( @docid =""00123"" or @docid =""00456"") AND [-a_number-] {+@a_number+} is not NULL"

isit possible to use "diff" as the command? – user2518789 Jun 25 '13 at 06:50
I don't think so, or I've never found the option to make him do it :-) – Ju Liu Jun 25 '13 at 06:54
