Comment:
I need to compare two files and get the difference between the two files. F1 is the base file.I need to print out all the lines missing in F2, and the extra lines in F2 and also the mismatched lines between F1 and F2. If they are mismatching then i need to print out the exact column numbers where they are mismatching. I need to do this using unix and awk.Please help.

The output of diff command is diffcult to comprehend. and if both the files have the same contents but if the order is different, still it says they are different.
