Rather than diff(1), perhaps comm(1) is a better choice.  You still need to
sort the input files though:

   % sort file1 > file1.sorted
   % sort file2 > file2.sorted
   % comm -3 file1.sorted file2.sorted

This will print two columns of output.  The first column consists of lines
that are only in file1, and the second of lines that are only in file2.

	Cheers,
