Compare two files and mismatch report
Hi
I have two files f1 and f2 and comma separated file.
I need to comapre two files by field by field and not by whole line.
If they match then skip the line from both the files. If they don't match
write the mismatch record from f1 to f3.
Assume both the files are sorted on first field.

Code:
f1
a1,a2,a3,a4,a5,a6
b1,b21,b31,b4,b5,b5
c1,c2,c3,c4,c5,c6
 
f2
a1,a2,a3,a4,a5,a6
b1,b2,b3,b4,b5,b6
c1,c2,c3,c4,c51,c61
d1,d2,d3,d4,d5,d6
 
The Output f3
b1,b21,b31,b4,b5,b6
c1,c2,c3,c4,c5,c6

I don't want to compare line by line , this may be required to tuke the data in some field.
I am just looking for Perl or unix script, how should I proceed about this.

Thanks
Dgmm
