RE: Cygwin - diff command does not provide output

Dear Dave Korn,
Thanks for your help.
As you suggested, First me too thought that it might be due to -q option in effect.
So I tried -n, -y options. But still I am getting the same message as "Files x.txt y.txt differ".

And I tried ur other suggestions alias & Set.. Here also I could not find any entries like diff.
Is there any way, I can check if all the files related to diff command are available & if so Which are the directories I should check?

Once Again, thanks for your replies.
Regards
