 459 <h2 id="_description">DESCRIPTION</h2>
 460 <div class="sectionbody">
 461 <div class="paragraph">
 462 <p>The .<code>gitmodules</code> file, located in the top-level directory of a Git
 463 working tree, is a text file with a syntax matching the requirements
 464 of <a href="git-config.html">git-config(1)</a>.</p>
 465 </div>
 466 <div class="paragraph">
 467 <p>The file contains one subsection per submodule, and the subsection value
 468 is the name of the submodule. The name is set to the path where the
 469 submodule has been added unless it was customized with the <code>--name</code>
 470 option of <em>git submodule add</em>. Each submodule section also contains the
 471 following required keys:</p>
 472 </div>
 473 <div class="dlist">
 474 <dl>
 475 <dt class="hdlist1">submodule.&lt;name&gt;.path</dt>
 476 <dd>
 477 <p>Defines the path, relative to the top-level directory of the Git
 478 working tree, where the submodule is expected to be checked out.
 479 The path name must not end with a <code>/</code>. All submodule paths must
 480 be unique within the .<code>gitmodules</code> file.</p>
 481 </dd>
 482 <dt class="hdlist1">submodule.&lt;name&gt;.url</dt>
 483 <dd>
 484 <p>Defines a URL from which the submodule repository can be cloned.
 485 This may be either an absolute URL ready to be passed to
 486 <a href="git-clone.html">git-clone(1)</a> or (if it begins with .<code>/</code> or <code>..</code><code>/</code>) a location
 487 relative to the superproject&#8217;s origin repository.</p>
 488 </dd>
 489 </dl>
 490 </div>
 491 <div class="paragraph">
 492 <p>In addition, there are a number of optional keys:</p>
 493 </div>
 494 <div class="dlist">
 495 <dl>
 496 <dt class="hdlist1">submodule.&lt;name&gt;.update</dt>
 497 <dd>
 498 <p>Defines the default update procedure for the named submodule,
 499 i.e. how the submodule is updated by the <code>git</code> <code>submodule</code> <code>update</code>
 500 command in the superproject. This is only used by <code>git</code>
 501 <code>submodule</code> <code>init</code> to initialize the configuration variable of
 502 the same name. Allowed values here are <em>checkout</em>, <em>rebase</em>,
 503 <em>merge</em> or <em>none</em>, but not <em>!command</em> (for security reasons).
 504 See the description of the <em>update</em> command in
 505 <a href="git-submodule.html">git-submodule(1)</a> for more details.</p>
 506 </dd>
 507 <dt class="hdlist1">submodule.&lt;name&gt;.branch</dt>
 508 <dd>
 509 <p>A remote branch name for tracking updates in the upstream submodule.
 510 If the option is not specified, it defaults to the remote <code>HEAD</code>.
 511 A special value of . is used to indicate that the name of the branch
 512 in the submodule should be the same name as the current branch in the
 513 current repository.  See the <code>--remote</code> documentation in
 514 <a href="git-submodule.html">git-submodule(1)</a> for details.</p>
 515 </dd>
 516 <dt class="hdlist1">submodule.&lt;name&gt;.fetchRecurseSubmodules</dt>
 517 <dd>
 518 <p>This option can be used to control recursive fetching of this
 519 submodule. If this option is also present in the submodule&#8217;s entry in
 520 .<code>git/config</code> of the superproject, the setting there will override the
 521 one found in .<code>gitmodules</code>.
 522 Both settings can be overridden on the command line by using the
 523 <code>--</code>[<code>no-</code>]<code>recurse-submodules</code> option to <code>git</code> <code>fetch</code> and <code>git</code> <code>pull</code>.</p>
 524 </dd>
 525 <dt class="hdlist1">submodule.&lt;name&gt;.ignore</dt>
 526 <dd>
 527 <p>Defines under what circumstances <code>git</code> <code>status</code> and the diff family show
 528 a submodule as modified. The following values are supported:</p>
 529 <div class="openblock">
 530 <div class="content">
 531 <div class="dlist">
 532 <dl>
 533 <dt class="hdlist1">all</dt>
 534 <dd>
 535 <p>The submodule will never be considered modified (but will
 536 nonetheless show up in the output of status and commit when it has
 537 been staged).</p>
 538 </dd>
 539 <dt class="hdlist1">dirty</dt>
 540 <dd>
 541 <p>All changes to the submodule&#8217;s work tree will be ignored, only
 542 committed differences between the <code>HEAD</code> of the submodule and its
 543 recorded state in the superproject are taken into account.</p>
 544 </dd>
 545 <dt class="hdlist1">untracked</dt>
 546 <dd>
 547 <p>Only untracked files in submodules will be ignored.
 548 Committed differences and modifications to tracked files will show
 549 up.</p>
 550 </dd>
 551 <dt class="hdlist1">none</dt>
 552 <dd>
 553 <p>No modifications to submodules are ignored, all of committed
 554 differences, and modifications to tracked and untracked files are
 555 shown. This is the default option.</p>
 556 </dd>
 557 </dl>
 558 </div>
 559 <div class="paragraph">
 560 <p>If this option is also present in the submodule&#8217;s entry in .<code>git/config</code>
 561 of the superproject, the setting there will override the one found in
 562 .<code>gitmodules</code>.</p>
 563 </div>
 564 <div class="paragraph">
 565 <p>Both settings can be overridden on the command line by using the
 566 <code>--ignore-submodules</code> option. The <code>git</code> <code>submodule</code> commands are not
 567 affected by this setting.</p>
 568 </div>
 569 </div>
 570 </div>
 571 </dd>
 572 <dt class="hdlist1">submodule.&lt;name&gt;.shallow</dt>
 573 <dd>
 574 <p>When set to true, a clone of this submodule will be performed as a
 575 shallow clone (with a history depth of 1) unless the user explicitly
 576 asks for a non-shallow clone.</p>

 586 <p>Git does not allow the .<code>gitmodules</code> file within a working tree to be a
 587 symbolic link, and will refuse to check out such a tree entry. This
 588 keeps behavior consistent when the file is accessed from the index or a
 589 tree versus from the filesystem, and helps Git reliably enforce security
 590 checks of the file contents.</p>
