                     20: .it file2,
                     21: which should be in sort,
                     22: and produces a three column output: lines only in

                     24: lines only in
                     25: .it file2;
                     26: and lines in both files.

                     29: .it file3
                     30: is given, the output will be placed there;
                     31: otherwise it will be written on the standard output.
