419 <h2 id="_description">DESCRIPTION</h2>
420 <div class="sectionbody">
421 <div class="paragraph"><p>A <tt>gitignore</tt> file specifies intentionally untracked files that
422 git should ignore.
423 Files already tracked by git are not affected; see the NOTES
424 below for details.</p></div>
425 <div class="paragraph"><p>Each line in a <tt>gitignore</tt> file specifies a pattern.
426 When deciding whether to ignore a path, git normally checks
427 <tt>gitignore</tt> patterns from multiple sources, with the following
428 order of precedence, from highest to lowest (within one level of
429 precedence, the last matching pattern decides the outcome):</p></div>
430 <div class="ulist"><ul>
431 <li>
433 Patterns read from the command line for those commands that support
434 them.
435 </p>
436 </li>
437 <li>
439 Patterns read from a <tt>.gitignore</tt> file in the same directory
440 as the path, or in any parent directory, with patterns in the
441 higher level files (up to the toplevel of the work tree) being overridden
442 by those in lower level files down to the directory containing the file.
443 These patterns match relative to the location of the
444 <tt>.gitignore</tt> file. A project normally includes such
445 <tt>.gitignore</tt> files in its repository, containing patterns for
446 files generated as part of the project build.
447 </p>
448 </li>
449 <li>
451 Patterns read from <tt>$GIT_DIR/info/exclude</tt>.
452 </p>
453 </li>
454 <li>
456 Patterns read from the file specified by the configuration
457 variable <em>core.excludesfile</em>.
458 </p>
459 </li>
460 </ul></div>
461 <div class="paragraph"><p>Which file to place a pattern in depends on how the pattern is meant to
462 be used. Patterns which should be version-controlled and distributed to
463 other repositories via clone (i.e., files that all developers will want
464 to ignore) should go into a <tt>.gitignore</tt> file. Patterns which are
465 specific to a particular repository but which do not need to be shared
466 with other related repositories (e.g., auxiliary files that live inside
467 the repository but are specific to one user&#8217;s workflow) should go into
468 the <tt>$GIT_DIR/info/exclude</tt> file. Patterns which a user wants git to
469 ignore in all situations (e.g., backup or temporary files generated by
470 the user&#8217;s editor of choice) generally go into a file specified by
471 <tt>core.excludesfile</tt> in the user&#8217;s <tt>~/.gitconfig</tt>.</p></div>
472 <div class="paragraph"><p>The underlying git plumbing tools, such as
473 <em>git ls-files</em> and <em>git read-tree</em>, read
474 <tt>gitignore</tt> patterns specified by command-line options, or from
475 files specified by command-line options. Higher-level git
476 tools, such as <em>git status</em> and <em>git add</em>,
477 use patterns from the sources specified above.</p></div>
478 </div>
479 <h2 id="_pattern_format">PATTERN FORMAT</h2>
480 <div class="sectionbody">
481 <div class="ulist"><ul>
482 <li>
484 A blank line matches no files, so it can serve as a separator
485 for readability.
486 </p>
487 </li>
488 <li>
490 A line starting with # serves as a comment.
491 </p>
492 </li>
493 <li>
495 An optional prefix <em>!</em> which negates the pattern; any
496 matching file excluded by a previous pattern will become
497 included again. If a negated pattern matches, this will
498 override lower precedence patterns sources.
499 </p>
500 </li>
501 <li>
503 If the pattern ends with a slash, it is removed for the
504 purpose of the following description, but it would only find
505 a match with a directory. In other words, <tt>foo/</tt> will match a
506 directory <tt>foo</tt> and paths underneath it, but will not match a
507 regular file or a symbolic link <tt>foo</tt> (this is consistent
508 with the way how pathspec works in general in git).
509 </p>
510 </li>
511 <li>
513 If the pattern does not contain a slash <em>/</em>, git treats it as
514 a shell glob pattern and checks for a match against the
515 pathname relative to the location of the <tt>.gitignore</tt> file
516 (relative to the toplevel of the work tree if not from a
517 <tt>.gitignore</tt> file).
518 </p>
519 </li>
520 <li>
522 Otherwise, git treats the pattern as a shell glob suitable
523 for consumption by fnmatch(3) with the FNM_PATHNAME flag:
524 wildcards in the pattern will not match a / in the pathname.
525 For example, "Documentation/&#42;.html" matches
526 "Documentation/git.html" but not "Documentation/ppc/ppc.html"
527 or "tools/perf/Documentation/perf.html".
528 </p>
529 </li>
530 <li>
532 A leading slash matches the beginning of the pathname.
533 For example, "/&#42;.c" matches "cat-file.c" but not
534 "mozilla-sha1/sha1.c".
535 </p>
536 </li>
537 </ul></div>

544 use <em>git update-index &#45;&#45;assume-unchanged</em>.</p></div>
