merge

MERGE(1)						      General Commands Manual							  MERGE(1)

NAME

       merge - three-way file merge

SYNOPSIS

       merge [ options ] file1 file2 file3

DESCRIPTION

       merge  incorporates all changes that lead from file2 to file3 into file1.  The result ordinarily goes into file1.  merge is useful for com-
       bining 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.

OPTIONS

       -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 's version number.

DIAGNOSTICS

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

BUGS

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