<h2 id="_description">DESCRIPTION</h2>
<div class="sectionbody">
<div class="paragraph">
<p>A <code>gitignore</code> file specifies intentionally untracked files that
Git should ignore.
Files already tracked by Git are not affected; see the NOTES
below for details.</p>
</div>
<div class="paragraph">
<p>Each line in a <code>gitignore</code> file specifies a pattern.
When deciding whether to ignore a path, Git normally checks
<code>gitignore</code> patterns from multiple sources, with the following
order of precedence, from highest to lowest (within one level of
precedence, the last matching pattern decides the outcome):</p>
</div>
<div class="ulist">
<ul>
<li>
<p>Patterns read from the command line for those commands that support
them.</p>
</li>
<li>
<p>Patterns read from a .<code>gitignore</code> file in the same directory
as the path, or in any parent directory (up to the top-level of the working
tree), with patterns in the higher level files being overridden by those in
lower level files down to the directory containing the file. These patterns
match relative to the location of the .<code>gitignore</code> file.  A project normally
includes such .<code>gitignore</code> files in its repository, containing patterns for
files generated as part of the project build.</p>
</li>
<li>
<p>Patterns read from <code>$GIT_DIR/info/exclude</code>.</p>
</li>
<li>
<p>Patterns read from the file specified by the configuration
variable <code>core.excludesFile</code>.</p>
</li>
</ul>
</div>
<div class="paragraph">
<p>Which file to place a pattern in depends on how the pattern is meant to
be used.</p>
</div>
<div class="ulist">
<ul>
<li>
<p>Patterns which should be version-controlled and distributed to
other repositories via clone (i.e., files that all developers will want
to ignore) should go into a .<code>gitignore</code> file.</p>
</li>
<li>
<p>Patterns which are
specific to a particular repository but which do not need to be shared
with other related repositories (e.g., auxiliary files that live inside
the repository but are specific to one user&#8217;s workflow) should go into
the <code>$GIT_DIR/info/exclude</code> file.</p>
</li>
<li>
<p>Patterns which a user wants Git to
ignore in all situations (e.g., backup or temporary files generated by
the user&#8217;s editor of choice) generally go into a file specified by
<code>core.excludesFile</code> in the user&#8217;s <code>~/.gitconfig</code>. Its default value is
$XDG_CONFIG_HOME/git/ignore. If $XDG_CONFIG_HOME is either not set or
empty, $HOME/.config/git/ignore is used instead.</p>
</li>
</ul>
</div>
<div class="paragraph">
<p>The underlying Git plumbing tools, such as
<em>git ls-files</em> and <em>git read-tree</em>, read
<code>gitignore</code> patterns specified by command-line options, or from
files specified by command-line options.  Higher-level Git
tools, such as <em>git status</em> and <em>git add</em>,
use patterns from the sources specified above.</p>
</div>
</div>
</div>
<div class="sect1">
<h2 id="_pattern_format">PATTERN FORMAT</h2>
<div class="sectionbody">
<div class="ulist">
<ul>
<li>
<p>A blank line matches no files, so it can serve as a separator
for readability.</p>
</li>
<li>
<p>A line starting with # serves as a comment.
Put a backslash ("\") in front of the first hash for patterns
that begin with a hash.</p>
</li>
<li>
<p>Trailing spaces are ignored unless they are quoted with backslash
("\").</p>
</li>
<li>
<p>An optional prefix "!" which negates the pattern; any
matching file excluded by a previous pattern will become
included again. It is not possible to re-include a file if a parent
directory of that file is excluded. Git doesn&#8217;t list excluded
directories for performance reasons, so any patterns on contained
files have no effect, no matter where they are defined.
Put a backslash ("\") in front of the first "!" for patterns
that begin with a literal "!", for example, "\!important!.<code>txt</code>".</p>
</li>
<li>
<p>The slash "<code>/</code>" is used as the directory separator. Separators may
occur at the beginning, middle or end of the .<code>gitignore</code> search pattern.</p>
</li>
<li>
<p>If there is a separator at the beginning or middle (or both) of the
pattern, then the pattern is relative to the directory level of the
particular .<code>gitignore</code> file itself. Otherwise the pattern may also
match at any level below the .<code>gitignore</code> level.</p>
</li>
<li>
<p>If there is a separator at the end of the pattern then the pattern
will only match directories, otherwise the pattern can match both
files and directories.</p>
</li>
<li>
<p>For example, a pattern <code>doc/frotz/</code> matches <code>doc/frotz</code> directory,
but not <code>a/doc/frotz</code> directory; however <code>frotz/</code> matches <code>frotz</code>
and <code>a/frotz</code> that is a directory (all paths are relative from
the .<code>gitignore</code> file).</p>
</li>
<li>
<p>An asterisk "*" matches anything except a slash.
The character "?" matches any one character except "<code>/</code>".
The range notation, e.g. [<code>a-zA-Z</code>], can be used to match
one of the characters in a range. See fnmatch(3) and the
FNM_PATHNAME flag for a more detailed description.</p>
</li>
</ul>
</div>
<div class="paragraph">
<p>Two consecutive asterisks ("**") in patterns matched against
full pathname may have special meaning:</p>
</div>
<div class="ulist">
<ul>
<li>
<p>A leading "**" followed by a slash means match in all
directories. For example, "**/foo" matches file or directory
"<code>foo</code>" anywhere, the same as pattern "<code>foo</code>". "**/foo/bar"
matches file or directory "<code>bar</code>" anywhere that is directly
under directory "<code>foo</code>".</p>
</li>
<li>
<p>A trailing "<code>/</code>**" matches everything inside. For example,
"<code>abc/</code>**" matches all files inside directory "<code>abc</code>", relative
to the location of the .<code>gitignore</code> file, with infinite depth.</p>
</li>
<li>
<p>A slash followed by two consecutive asterisks then a slash
matches zero or more directories. For example, "<code>a/</code>**/b"
matches "<code>a/b</code>", "<code>a/x/b</code>", "<code>a/x/y/b</code>" and so on.</p>
</li>
<li>
<p>Other consecutive asterisks are considered regular asterisks and
will match according to the previous rules.</p>
</li>
</ul>
</div>
</div>
</div>
<div class="sect1">
<h2 id="_configuration">CONFIGURATION</h2>
<div class="sectionbody">
<div class="paragraph">
<p>The optional configuration variable <code>core.excludesFile</code> indicates a path to a
file containing patterns of file names to exclude, similar to
<code>$GIT_DIR/info/exclude</code>.  Patterns in the exclude file are used in addition to
those in <code>$GIT_DIR/info/exclude</code>.</p>
</div>
</div>
</div>
<div class="sect1">
<h2 id="_notes">NOTES</h2>
<div class="sectionbody">
<div class="paragraph">
<p>The purpose of gitignore files is to ensure that certain files
not tracked by Git remain untracked.</p>
</div>
<div class="paragraph">
<p>To stop tracking a file that is currently tracked, use
<em>git rm --cached</em> to remove the file from the index. The filename
can then be added to the .<code>gitignore</code> file to stop the file from
being reintroduced in later commits.</p>
</div>
<div class="paragraph">
<p>Git does not follow symbolic links when accessing a .<code>gitignore</code> file in
the working tree. This keeps behavior consistent when the file is
accessed from the index or a tree versus from the filesystem.</p>
</div>
</div>
</div>
<div class="sect1">
<h2 id="_examples">EXAMPLES</h2>
<div class="sectionbody">
<div class="ulist">
<ul>
<li>
<p>The pattern <code>hello.</code>* matches any file or directory
whose name begins with <code>hello.</code>. If one wants to restrict
this only to the directory and not in its subdirectories,
one can prepend the pattern with a slash, i.e. <code>/hello.</code>*;
the pattern now matches <code>hello.txt</code>, <code>hello.c</code> but not
<code>a/hello.java</code>.</p>
</li>
<li>
<p>The pattern <code>foo/</code> will match a directory <code>foo</code> and
paths underneath it, but will not match a regular file
or a symbolic link <code>foo</code> (this is consistent with the
way how pathspec works in general in Git)</p>
</li>
<li>
<p>The pattern <code>doc/frotz</code> and <code>/doc/frotz</code> have the same effect
in any .<code>gitignore</code> file. In other words, a leading slash
is not relevant  if there is already a middle slash in
the pattern.</p>
</li>
<li>
<p>The pattern <code>foo/</code>*, matches <code>foo/test.json</code>
(a regular file), <code>foo/bar</code> (a directory), but it does not match
<code>foo/bar/hello.c</code> (a regular file), as the asterisk in the
pattern does not match <code>bar/hello.c</code> which has a slash in it.</p>
</li>
</ul>
