       merge - three-way file merge

       merge [ options ] file1 file2 file3

       merge incorporates all changes that lead from file2 to file3 into
       file1.  The result ordinarily goes into file1.  merge is useful for
       combining separate changes to an original.  Suppose file2 is the
       original, and both file1 and file3 are modifications of file2.  Then
       merge combines both changes.

       A conflict occurs if both file1 and file3 have changes in a common
       segment of lines.  If a conflict is found, merge normally outputs a
       warning and brackets the conflict with <<<<<<< and >>>>>>> lines.  A
       typical conflict will look like this:

              <<<<<<< file A
              lines in file A
              lines in file B
              >>>>>>> file B

       If there are conflicts, the user should edit the result and delete one
       of the alternatives.

       -A     Output conflicts using the -A style of diff3(1), if supported by
              diff3.  This merges all changes leading from file2 to file3 into
              file1, and generates the most verbose output.

       -E, -e These options specify conflict styles that generate less
              information than -A.  See diff3(1) for details.  The default is
              -E.  With -e, merge does not warn about conflicts.

       -L label
              This option may be given up to three times, and specifies labels
              to be used in place of the corresponding file names in conflict
              reports.  That is, merge -L x -L y -L z a b c generates output
              that looks like it came from files x, y and z instead of from
              files a, b and c.

       -p     Send results to standard output instead of overwriting file1.

       -q     Quiet; do not warn about conflicts.

       -V     Print RCS's version number.

       Exit status is 0 for no conflicts, 1 for some conflicts, 2 for trouble.

       The full documentation for RCS is maintained as a Texinfo manual.  If
       the info(1) and RCS programs are properly installed at your site, the

              info rcs

       should give you access to the complete manual.  Additionally, the RCS


       has news and links to the latest release, development site, etc.

       It normally does not make sense to merge binary files as if they were
       text, but merge tries to do it anyway.
