Hi All,

This forum helped me a lot! Thanks for your help.

Well, Again I am in problem I need to write a shell script which can compare two files(text files) character wise.

eg.
underscore is space.
------FILE 1---------------
A_B_C
D_E_F
G_H_I
------------------------------

--------FILE 2--------------
A_BC
D_E_F
GH__I
---------------------------

Output should be
_C -> C_
_H -> H_

Actual problem: I need to write a shell script which can give me difference character by character not by line (using comm)

Please HELP HELP!

Thanks,
Vaibhav
