        SYNTAX

        diff3 [ -ex3 ] file1 file2 file3


        DESCRIPTION

        Diff3 compares three versions of a file, and publishes
        disagreeing ranges of text flagged with these codes:

             ====            All three files differ

             ====1           File1 is different

             ====2           File2 is different

             ====3           File3 is different

        The type of change that occurs in converting a given range of a
        given file to some other is indicated in one of these ways:

             f : n1 a        Text is to be appended after line number n1
                             in file f, where f = 1, 2, or 3.

             f : n1 , n2 c   Text is to be changed in the range line n1
                             to line n2.  If n1 = n2, the range may be
                             abbreviated to n1.

        The original contents of the range follows immediately after a c
        indication.  When the contents of two files are identical, the
        contents of the lower-numbered file are suppressed.

        Under the -e option, diff3 publishes a script for the editor ed
        that will incorporate into file1 all changes between file2 and
        file3, i.e., the changes that normally would be flagged ==== and
        ====3.  Option -x (-3) produces a script to incorporate only
        changes flagged ==== (====3).  The following command will apply
        the resulting script to file1.

                        (cat script; echo '1,$p') | ed - file1
