<h2>NAME</h2>
<div class="sectionbody">
<p>git-merge-file -
Run a three-way file merge
</p>
</div>
</div>
<h2 id="_synopsis">SYNOPSIS</h2>
<div class="sectionbody">
<div class="verseblock">
<div class="verseblock-content"><em>git merge-file</em> [-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></div>
<div class="verseblock-attribution">
</div></div>
</div>
<h2 id="_description">DESCRIPTION</h2>
<div class="sectionbody">
<div class="paragraph"><p><em>git merge-file</em> incorporates all changes that lead from the <tt><base-file></tt>
to <tt><other-file></tt> into <tt><current-file></tt>. The result ordinarily goes into
<tt><current-file></tt>. <em>git merge-file</em> is useful for combining separate changes
to an original. Suppose <tt><base-file></tt> is the original, and both
<tt><current-file></tt> and <tt><other-file></tt> are modifications of <tt><base-file></tt>,
then <em>git merge-file</em> combines both changes.</p></div>
<div class="paragraph"><p>A conflict occurs if both <tt><current-file></tt> and <tt><other-file></tt> have changes
in a common segment of lines. If a conflict is found, <em>git merge-file</em>
normally outputs a warning and brackets the conflict with lines containing
<<<<<<< and >>>>>>> markers. A typical conflict will look like this:</p></div>
<div class="literalblock">
<div class="content">
<pre><tt><<<<<<< A
lines in file A
=======
lines in file B
>>>>>>> B</tt></pre>
</div></div>
<div class="paragraph"><p>If there are conflicts, the user should edit the result and delete one of
the alternatives. When <tt>--ours</tt>, <tt>--theirs</tt>, or <tt>--union</tt> option is in effect,
however, these conflicts are resolved favouring lines from <tt><current-file></tt>,
lines from <tt><other-file></tt>, or lines from both respectively. The length of the
conflict markers can be given with the <tt>--marker-size</tt> option.</p></div>
<div class="paragraph"><p>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.</p></div>
<div class="paragraph"><p><em>git merge-file</em> is designed to be a minimal clone of RCS <em>merge</em>; that is, it
implements all of RCS <em>merge</em>'s functionality which is needed by
<a href="git.html">git(1)</a>.</p></div>
</div>
<h2 id="_options">OPTIONS</h2>
<div class="sectionbody">
<div class="dlist"><dl>
<dt class="hdlist1">
-L <label>
</dt>
<dd>
<p>
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,
<tt>git merge-file -L x -L y -L z a b c</tt> generates output that
looks like it came from files x, y and z instead of
from files a, b and c.
</p>
</dd>
<dt class="hdlist1">
-p
</dt>
<dd>
<p>
Send results to standard output instead of overwriting
<tt><current-file></tt>.
</p>
</dd>
<dt class="hdlist1">
-q
</dt>
<dd>
<p>
Quiet; do not warn about conflicts.
</p>
</dd>
<dt class="hdlist1">
--ours
</dt>
<dt class="hdlist1">
--theirs
</dt>
<dt class="hdlist1">
--union
</dt>
<dd>
<p>
Instead of leaving conflicts in the file, resolve conflicts
favouring our (or their or both) side of the lines.
</p>
</dd>
</dl></div>

<h2 id="_examples">EXAMPLES</h2>
<div class="sectionbody">
<div class="dlist"><dl>
<dt class="hdlist1">
git merge-file README.my README README.upstream
</dt>
<dd>
<p>
combines the changes of README.my and README.upstream since README,
tries to merge them and writes the result into README.my.

</dd>
<dt class="hdlist1">
git merge-file -L a -L b -L c tmp/a123 tmp/b234 tmp/c345

<dd>
<p>
merges tmp/a123 and tmp/c345 with the base tmp/b234, but uses labels
<tt>a</tt> and <tt>c</tt> instead of <tt>tmp/a123</tt> and <tt>tmp/c345</tt>.
