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. IDENTIFICATION
