 420 <div class="sectionbody">
 421 <div class="paragraph"><p>Use <tt>git mergetool</tt> to run one of several merge utilities to resolve
 422 merge conflicts.  It is typically run after <em>git merge</em>.</p></div>
 423 <div class="paragraph"><p>If one or more &lt;file&gt; parameters are given, the merge tool program will
 424 be run to resolve differences on each file.  If no &lt;file&gt; names are
 425 specified, <em>git mergetool</em> will run the merge tool program on every file
 426 with merge conflicts.</p></div>

 429 <div class="sectionbody">
 430 <div class="dlist"><dl>

 437 <dd>
 438 <p>
 439         Use the merge resolution program specified by &lt;tool&gt;.
 440         Valid merge tools are:
 441         araxis, bc3, diffuse, ecmerge, emerge, gvimdiff, kdiff3,
 442         meld, opendiff, p4merge, tkdiff, tortoisemerge, vimdiff and xxdiff.
 443 </p>
 444 <div class="paragraph"><p>If a merge resolution program is not specified, <em>git mergetool</em>
 445 will use the configuration variable <tt>merge.tool</tt>.  If the
 446 configuration variable <tt>merge.tool</tt> is not set, <em>git mergetool</em>
 447 will pick a suitable default.</p></div>
 448 <div class="paragraph"><p>You can explicitly provide a full path to the tool by setting the
 449 configuration variable <tt>mergetool.&lt;tool&gt;.path</tt>. For example, you
 450 can configure the absolute path to kdiff3 by setting
 451 <tt>mergetool.kdiff3.path</tt>. Otherwise, <em>git mergetool</em> assumes the
 452 tool is available in PATH.</p></div>
 453 <div class="paragraph"><p>Instead of running one of the known merge tool programs,
 454 <em>git mergetool</em> can be customized to run an alternative program
 455 by specifying the command line to invoke in a configuration
 456 variable <tt>mergetool.&lt;tool&gt;.cmd</tt>.</p></div>
 457 <div class="paragraph"><p>When <em>git mergetool</em> is invoked with this tool (either through the
 458 <tt>-t</tt> or <tt>--tool</tt> option or the <tt>merge.tool</tt> configuration
 459 variable) the configured command line will be invoked with <tt>$BASE</tt>
 460 set to the name of a temporary file containing the common base for
 461 the merge, if available; <tt>$LOCAL</tt> set to the name of a temporary
 462 file containing the contents of the file on the current branch;
 463 <tt>$REMOTE</tt> set to the name of a temporary file containing the
 464 contents of the file to be merged, and <tt>$MERGED</tt> set to the name
 465 of the file to which the merge tool should write the result of the
 466 merge resolution.</p></div>
 467 <div class="paragraph"><p>If the custom merge tool correctly indicates the success of a
 468 merge resolution with its exit code, then the configuration
 469 variable <tt>mergetool.&lt;tool&gt;.trustExitCode</tt> can be set to <tt>true</tt>.
 470 Otherwise, <em>git mergetool</em> will prompt the user to indicate the
 471 success of the resolution after the custom tool has exited.</p></div>
