git-merge-file - Run a three-way file merge
git merge-file [-L <current-name> [-L <base-name> [-L <other-name>]]]
[--ours|--theirs|--union] [-p|--stdout] [-q|--quiet] [--marker-size=<n>]
<current-file> <base-file> <other-file>
git merge-file incorporates all changes that lead from the <base-file> to <other-file>
into <current-file>. The result ordinarily goes into <current-file>. git merge-file is
useful for combining separate changes to an original. Suppose <base-file> is the original,
and both <current-file> and <other-file> are modifications of <base-file>, then git
merge-file combines both changes.
A conflict occurs if both <current-file> and <other-file> have changes in a common segment
of lines. If a conflict is found, git merge-file normally outputs a warning and brackets
the conflict with lines containing <<<<<<< and >>>>>>> markers. A typical conflict will
look like this:
lines in file A
lines in file B
If there are conflicts, the user should edit the result and delete one of the
alternatives. When --ours, --theirs, or --union option is in effect, however, these
conflicts are resolved favouring lines from <current-file>, lines from <other-file>, or
lines from both respectively. The length of the conflict markers can be given with the
The exit value of this program is negative on error, and the number of conflicts
otherwise. If the merge was clean, the exit value is 0.
git merge-file is designed to be a minimal clone of RCS merge; that is, it implements all
of RCS merge's functionality which is needed by git(1).
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, git merge-file -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.
Send results to standard output instead of overwriting <current-file>.
Quiet; do not warn about conflicts.
--ours, --theirs, --union
Instead of leaving conflicts in the file, resolve conflicts favouring our (or their or
both) side of the lines.
git merge-file README.my README README.upstream
combines the changes of README.my and README.upstream since README, tries to merge
them and writes the result into README.my.
git merge-file -L a -L b -L c tmp/a123 tmp/b234 tmp/c345
merges tmp/a123 and tmp/c345 with the base tmp/b234, but uses labels a and c instead
of tmp/a123 and tmp/c345.
