 <h2>NAME</h2>
 <div class="sectionbody">
 <p>gitrepository-layout -
  Git Repository Layout
 </p>
 </div>
 </div>
 <h2>SYNOPSIS</h2>
 <div class="sectionbody">
 <div class="para"><p>$GIT_DIR/*</p></div>
 </div>
 <h2 id="_description">DESCRIPTION</h2>
 <div class="sectionbody">
 <div class="para"><p>You may find these things in your git repository (<tt>.git</tt>
 directory for a repository associated with your working tree, or
 <tt>&lt;project&gt;.git</tt> directory for a public <em>bare</em> repository. It is
 also possible to have a working tree where <tt>.git</tt> is a plain
 ascii file containing <tt>gitdir: &lt;path&gt;</tt>, i.e. the path to the
 real git repository).</p></div>
 <div class="vlist"><dl>
 <dt>
 objects
 </dt>
 <dd>
 <p>
  Object store associated with this repository. Usually
  an object store is self sufficient (i.e. all the objects
  that are referred to by an object found in it are also
  found in it), but there are couple of ways to violate
  it.
 </p>
 <div class="olist"><ol>
 <li>
 <p>
 You could populate the repository by running a commit walker
 without <tt>-a</tt> option. Depending on which options are given, you
 could have only commit objects without associated blobs and
 trees this way, for example. A repository with this kind of
 incomplete object store is not suitable to be published to the
 outside world but sometimes useful for private repository.
 </p>
 </li>
 <li>
 <p>
 You also could have an incomplete but locally usable repository
 by cloning shallowly. See <a href="git-clone.html">git-clone(1)</a>.
 </p>
 </li>
 <li>
 <p>
 You can be using <tt>objects/info/alternates</tt> mechanism, or
 <tt>$GIT_ALTERNATE_OBJECT_DIRECTORIES</tt> mechanism to <em>borrow</em>
 objects from other object stores. A repository with this kind
 of incomplete object store is not suitable to be published for
 use with dumb transports but otherwise is OK as long as
 <tt>objects/info/alternates</tt> points at the right object stores
 it borrows from.
 </p>
 </li>
 </ol></div>
 </dd>
 <dt>
 objects/[0-9a-f][0-9a-f]
 </dt>
 <dd>
 <p>
  Traditionally, each object is stored in its own file.
  They are split into 256 subdirectories using the first
  two letters from its object name to keep the number of
  directory entries <tt>objects</tt> directory itself needs to
  hold. Objects found here are often called <em>unpacked</em>
  (or <em>loose</em>) objects.
 </p>
 </dd>
 <dt>
 objects/pack
 </dt>
 <dd>
 <p>
  Packs (files that store many object in compressed form,
  along with index files to allow them to be randomly
  accessed) are found in this directory.
 </p>
 </dd>
 <dt>
 objects/info
 </dt>
 <dd>
 <p>
  Additional information about the object store is
  recorded in this directory.
 </p>
 </dd>
 <dt>
 objects/info/packs
 </dt>
 <dd>
 <p>
  This file is to help dumb transports discover what packs
  are available in this object store. Whenever a pack is
  added or removed, <tt>git update-server-info</tt> should be run
  to keep this file up-to-date if the repository is
  published for dumb transports. <em>git-repack</em> does this
  by default.
 </p>
 </dd>
 <dt>
 objects/info/alternates
 </dt>
 <dd>
 <p>
  This file records paths to alternate object stores that
  this object store borrows objects from, one pathname per
  line. Note that not only native Git tools use it locally,
  but the HTTP fetcher also tries to use it remotely; this
  will usually work if you have relative paths (relative
  to the object database, not to the repository!) in your
  alternates file, but it will not work if you use absolute
  paths unless the absolute path in filesystem and web URL
  is the same. See also <em>objects/info/http-alternates</em>.
 </p>
 </dd>
 <dt>
 objects/info/http-alternates
 </dt>
 <dd>
 <p>
  This file records URLs to alternate object stores that
  this object store borrows objects from, to be used when
  the repository is fetched over HTTP.
 </p>
 </dd>
 <dt>
 refs
 </dt>
 <dd>
 <p>
  References are stored in subdirectories of this
  directory. The <em>git-prune</em> command knows to keep
  objects reachable from refs found in this directory and
  its subdirectories.
 </p>
 </dd>
 <dt>
 refs/heads/<tt>name</tt>
 </dt>
 <dd>
 <p>
  records tip-of-the-tree commit objects of branch <tt>name</tt>
 </p>
 </dd>
 <dt>
 refs/tags/<tt>name</tt>
 </dt>
 <dd>
 <p>
  records any object name (not necessarily a commit
  object, or a tag object that points at a commit object).
 </p>
 </dd>
 <dt>
 refs/remotes/<tt>name</tt>
 </dt>
 <dd>
 <p>
  records tip-of-the-tree commit objects of branches copied
  from a remote repository.
 </p>
 </dd>
 <dt>
 packed-refs
 </dt>
 <dd>
 <p>
  records the same information as refs/heads/, refs/tags/,
  and friends record in a more efficient way. See
  <a href="git-pack-refs.html">git-pack-refs(1)</a>.
 </p>
 </dd>
 <dt>
 HEAD
 </dt>
 <dd>
 <p>
  A symref (see glossary) to the <tt>refs/heads/</tt> namespace
  describing the currently active branch. It does not mean
  much if the repository is not associated with any working tree
  (i.e. a <em>bare</em> repository), but a valid git repository
  <strong>must</strong> have the HEAD file; some porcelains may use it to
  guess the designated "default" branch of the repository
  (usually <em>master</em>). It is legal if the named branch
  <em>name</em> does not (yet) exist. In some legacy setups, it is
  a symbolic link instead of a symref that points at the current
  branch.
 </p>
 <div class="para"><p>HEAD can also record a specific commit directly, instead of
 being a symref to point at the current branch. Such a state
 is often called <em>detached HEAD</em>, and almost all commands work
 identically as normal. See <a href="git-checkout.html">git-checkout(1)</a> for
 details.</p></div>
 </dd>
 <dt>
 branches
 </dt>
 <dd>
 <p>
  A slightly deprecated way to store shorthands to be used
  to specify URL to <em>git-fetch</em>, <em>git-pull</em> and <em>git-push</em>
  commands is to store a file in <tt>branches/&lt;name&gt;</tt> and
  give <em>name</em> to these commands in place of <em>repository</em>
  argument.
 </p>
 </dd>
 <dt>
 hooks
 </dt>
 <dd>
 <p>
  Hooks are customization scripts used by various git
  commands. A handful of sample hooks are installed when
  <em>git-init</em> is run, but all of them are disabled by
  default. To enable, they need to be made executable.
  Read <a href="githooks.html">githooks(5)</a> for more details about
  each hook.
 </p>
 </dd>
 <dt>
 index
 </dt>
 <dd>
 <p>
  The current index file for the repository. It is
  usually not found in a bare repository.
 </p>
 </dd>
 <dt>
 info
 </dt>
 <dd>
 <p>
  Additional information about the repository is recorded
  in this directory.
 </p>
 </dd>
 <dt>
 info/refs
 </dt>
 <dd>
 <p>
  This file helps dumb transports discover what refs are
  available in this repository. If the repository is
  published for dumb transports, this file should be
  regenerated by <em>git-update-server-info</em> every time a tag
  or branch is created or modified. This is normally done
  from the <tt>hooks/update</tt> hook, which is run by the
  <em>git-receive-pack</em> command when you <em>git-push</em> into the
  repository.
 </p>
 </dd>
 <dt>
 info/grafts
 </dt>
 <dd>
 <p>
  This file records fake commit ancestry information, to
  pretend the set of parents a commit has is different
  from how the commit was actually created. One record
  per line describes a commit and its fake parents by
  listing their 40-byte hexadecimal object names separated
  by a space and terminated by a newline.
 </p>
 </dd>
 <dt>
 info/exclude
 </dt>
 <dd>
 <p>
  This file, by convention among Porcelains, stores the
  exclude pattern list. <tt>.gitignore</tt> is the per-directory
  ignore file. <em>git-status</em>, <em>git-add</em>, <em>git-rm</em> and
  <em>git-clean</em> look at it but the core git commands do not look
  at it. See also: <a href="gitignore.html">gitignore(5)</a>.
 </p>
 </dd>
 <dt>
 remotes
 </dt>
 <dd>
 <p>
  Stores shorthands to be used to give URL and default
  refnames to interact with remote repository to
  <em>git-fetch</em>, <em>git-pull</em> and <em>git-push</em> commands.
 </p>
 </dd>
 <dt>
 logs
 </dt>
 <dd>
 <p>
  Records of changes made to refs are stored in this
  directory. See <a href="git-update-ref.html">git-update-ref(1)</a>
  for more information.
 </p>
 </dd>
 <dt>
 logs/refs/heads/<tt>name</tt>
 </dt>
 <dd>
 <p>
  Records all changes made to the branch tip named <tt>name</tt>.
 </p>
 </dd>
 <dt>
 logs/refs/tags/<tt>name</tt>
 </dt>
 <dd>
 <p>
  Records all changes made to the tag named <tt>name</tt>.
 </p>
 </dd>
 <dt>
 shallow
 </dt>
 <dd>
 <p>
  This is similar to <tt>info/grafts</tt> but is internally used
  and maintained by shallow clone mechanism. See <tt>--depth</tt>
  option to <a href="git-clone.html">git-clone(1)</a> and <a href="git-fetch.html">git-fetch(1)</a>.

	<div class="sectionbody">
	<div class="para"><p>You may find these things in your git repository (<tt>.git</tt>
	directory for a repository associated with your working tree, or
	<tt><project>.git</tt> directory for a public <em>bare</em> repository. It is
	also possible to have a working tree where <tt>.git</tt> is a plain
	ascii file containing <tt>gitdir: <path></tt>, i.e. the path to the
	real git repository).</p></div>
	<div class="vlist"><dl>
	<dt>
	objects
	</dt>
	<dd>
	<p>
	Object store associated with this repository. Usually
	an object store is self sufficient (i.e. all the objects
	that are referred to by an object found in it are also
	found in it), but there are couple of ways to violate
	it.
	</p>
	<div class="olist"><ol>
	<li>
	<p>
	You could populate the repository by running a commit walker
	without <tt>-a</tt> option. Depending on which options are given, you
	could have only commit objects without associated blobs and
	trees this way, for example. A repository with this kind of
	incomplete object store is not suitable to be published to the
	outside world but sometimes useful for private repository.
	</p>
	</li>
	<li>
	<p>
	You also could have an incomplete but locally usable repository
	by cloning shallowly. See <a href="git-clone.html">git-clone(1)</a>.
	</p>
	</li>
	<li>
	<p>
	You can be using <tt>objects/info/alternates</tt> mechanism, or
	<tt>$GIT_ALTERNATE_OBJECT_DIRECTORIES</tt> mechanism to <em>borrow</em>
	objects from other object stores. A repository with this kind
	of incomplete object store is not suitable to be published for
	use with dumb transports but otherwise is OK as long as
	<tt>objects/info/alternates</tt> points at the right object stores
	it borrows from.
	</p>
	</li>
	</ol></div>
	</dd>
	<dt>
	objects/[0-9a-f][0-9a-f]
	</dt>
	<dd>
	<p>
	Traditionally, each object is stored in its own file.
	They are split into 256 subdirectories using the first
	two letters from its object name to keep the number of
	directory entries <tt>objects</tt> directory itself needs to
	hold. Objects found here are often called <em>unpacked</em>
	(or <em>loose</em>) objects.
	</p>
	</dd>
	<dt>
	objects/pack
	</dt>
	<dd>
	<p>
	Packs (files that store many object in compressed form,
	along with index files to allow them to be randomly
	accessed) are found in this directory.
	</p>
	</dd>
	<dt>
	objects/info
	</dt>
	<dd>
	<p>
	Additional information about the object store is
	recorded in this directory.
	</p>
	</dd>
	<dt>
	objects/info/packs
	</dt>
	<dd>
	<p>
	This file is to help dumb transports discover what packs
	are available in this object store. Whenever a pack is
	added or removed, <tt>git update-server-info</tt> should be run
	to keep this file up-to-date if the repository is
	published for dumb transports. <em>git-repack</em> does this
	by default.
	</p>
	</dd>
	<dt>
	objects/info/alternates
	</dt>
	<dd>
	<p>
	This file records paths to alternate object stores that
	this object store borrows objects from, one pathname per
	line. Note that not only native Git tools use it locally,
	but the HTTP fetcher also tries to use it remotely; this
	will usually work if you have relative paths (relative
	to the object database, not to the repository!) in your
	alternates file, but it will not work if you use absolute
	paths unless the absolute path in filesystem and web URL
	is the same. See also <em>objects/info/http-alternates</em>.
	</p>
	</dd>
	<dt>
	objects/info/http-alternates
	</dt>
	<dd>
	<p>
	This file records URLs to alternate object stores that
	this object store borrows objects from, to be used when
	the repository is fetched over HTTP.
	</p>
	</dd>
	<dt>
	refs
	</dt>
	<dd>
	<p>
	References are stored in subdirectories of this
	directory. The <em>git-prune</em> command knows to keep
	objects reachable from refs found in this directory and
	its subdirectories.
	</p>
	</dd>
	<dt>
	refs/heads/<tt>name</tt>
	</dt>
	<dd>
	<p>
	records tip-of-the-tree commit objects of branch <tt>name</tt>
	</p>
	</dd>
	<dt>
	refs/tags/<tt>name</tt>
	</dt>
	<dd>
	<p>
	records any object name (not necessarily a commit
	object, or a tag object that points at a commit object).
	</p>
	</dd>
	<dt>
	refs/remotes/<tt>name</tt>
	</dt>
	<dd>
	<p>
	records tip-of-the-tree commit objects of branches copied
	from a remote repository.
	</p>
	</dd>
	<dt>
	packed-refs
	</dt>
	<dd>
	<p>
	records the same information as refs/heads/, refs/tags/,
	and friends record in a more efficient way. See
	<a href="git-pack-refs.html">git-pack-refs(1)</a>.
	</p>
	</dd>
	<dt>
	HEAD
	</dt>
	<dd>
	<p>
	A symref (see glossary) to the <tt>refs/heads/</tt> namespace
	describing the currently active branch. It does not mean
	much if the repository is not associated with any working tree
	(i.e. a <em>bare</em> repository), but a valid git repository
	<strong>must</strong> have the HEAD file; some porcelains may use it to
	guess the designated "default" branch of the repository
	(usually <em>master</em>). It is legal if the named branch
	<em>name</em> does not (yet) exist. In some legacy setups, it is
	a symbolic link instead of a symref that points at the current
	branch.
	</p>
	<div class="para"><p>HEAD can also record a specific commit directly, instead of
	being a symref to point at the current branch. Such a state
	is often called <em>detached HEAD</em>, and almost all commands work
	identically as normal. See <a href="git-checkout.html">git-checkout(1)</a> for
	details.</p></div>
	</dd>
	<dt>
	branches
	</dt>
	<dd>
	<p>
	A slightly deprecated way to store shorthands to be used
	to specify URL to <em>git-fetch</em>, <em>git-pull</em> and <em>git-push</em>
	commands is to store a file in <tt>branches/<name></tt> and
	give <em>name</em> to these commands in place of <em>repository</em>
	argument.
	</p>
	</dd>
	<dt>
	hooks
	</dt>
	<dd>
	<p>
	Hooks are customization scripts used by various git
	commands. A handful of sample hooks are installed when
	<em>git-init</em> is run, but all of them are disabled by
	default. To enable, they need to be made executable.
	Read <a href="githooks.html">githooks(5)</a> for more details about
	each hook.
	</p>
	</dd>
	<dt>
	index
	</dt>
	<dd>
	<p>
	The current index file for the repository. It is
	usually not found in a bare repository.
	</p>
	</dd>
	<dt>
	info
	</dt>
	<dd>
	<p>
	Additional information about the repository is recorded
	in this directory.
	</p>
	</dd>
	<dt>
	info/refs
	</dt>
	<dd>
	<p>
	This file helps dumb transports discover what refs are
	available in this repository. If the repository is
	published for dumb transports, this file should be
	regenerated by <em>git-update-server-info</em> every time a tag
	or branch is created or modified. This is normally done
	from the <tt>hooks/update</tt> hook, which is run by the
	<em>git-receive-pack</em> command when you <em>git-push</em> into the
	repository.
	</p>
	</dd>
	<dt>
	info/grafts
	</dt>
	<dd>
	<p>
	This file records fake commit ancestry information, to
	pretend the set of parents a commit has is different
	from how the commit was actually created. One record
	per line describes a commit and its fake parents by
	listing their 40-byte hexadecimal object names separated
	by a space and terminated by a newline.
	</p>
	</dd>
	<dt>
	info/exclude
	</dt>
	<dd>
	<p>
	This file, by convention among Porcelains, stores the
	exclude pattern list. <tt>.gitignore</tt> is the per-directory
	ignore file. <em>git-status</em>, <em>git-add</em>, <em>git-rm</em> and
	<em>git-clean</em> look at it but the core git commands do not look
	at it. See also: <a href="gitignore.html">gitignore(5)</a>.
	</p>
	</dd>
	<dt>
	remotes
	</dt>
	<dd>
	<p>
	Stores shorthands to be used to give URL and default
	refnames to interact with remote repository to
	<em>git-fetch</em>, <em>git-pull</em> and <em>git-push</em> commands.
	</p>
	</dd>
	<dt>
	logs
	</dt>
	<dd>
	<p>
	Records of changes made to refs are stored in this
	directory. See <a href="git-update-ref.html">git-update-ref(1)</a>
	for more information.
	</p>
	</dd>
	<dt>
	logs/refs/heads/<tt>name</tt>
	</dt>
	<dd>
	<p>
	Records all changes made to the branch tip named <tt>name</tt>.
	</p>
	</dd>
	<dt>
	logs/refs/tags/<tt>name</tt>
	</dt>
	<dd>
	<p>
	Records all changes made to the tag named <tt>name</tt>.
	</p>
	</dd>
	<dt>
	shallow
	</dt>
	<dd>
	<p>
	This is similar to <tt>info/grafts</tt> but is internally used
	and maintained by shallow clone mechanism. See <tt>--depth</tt>
	option to <a href="git-clone.html">git-clone(1)</a> and <a href="git-fetch.html">git-fetch(1)</a>.
