MERGE(1)                                                              MERGE(1)

       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 correspond-
              ing 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 's version number.

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

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