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, gitmerge-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 --marker-size option.
The exit value of this program is negative on error, and the number
of conflicts otherwise (truncated to 127 if there are more than that
many conflicts). 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
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
Quiet; do not warn about conflicts.
Show conflicts in "diff3" style.
--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.
