 <div class="dlist"><dl>
 <dt class="hdlist1">
 -q
 </dt>
 <dt class="hdlist1">

 </dt>
 <dd>
 <p>
 Only print error and warning messages, all other output will be suppressed.
 </p>
 </dd>
 <dt class="hdlist1">
 --bare
 </dt>
 <dd>
 <p>
 Create a bare repository. If GIT_DIR environment is not set, it is set to the
 current working directory.
 </p>
 </dd>
 <dt class="hdlist1">
 --template=&lt;template_directory&gt;
 </dt>
 <dd>
 <p>
 Specify the directory from which templates will be used. (See the "TEMPLATE
 DIRECTORY" section below.)
 </p>
 </dd>
 <dt class="hdlist1">
 --shared[=(false|true|umask|group|all|world|everybody|0xxx)]
 </dt>
 <dd>
 <p>
 Specify that the git repository is to be shared amongst several users. This
 allows users belonging to the same group to push into that
 repository. When specified, the config variable "core.sharedRepository" is
 set so that files and directories under <tt>$GIT_DIR</tt> are created with the
 requested permissions. When not specified, git will use permissions reported
 by umask(2).
 </p>
 </dd>
 </dl></div>
 <div class="paragraph"><p>The option can have the following values, defaulting to <em>group</em> if no value
 is given:</p></div>
 <div class="ulist"><ul>
 <li>
 <p>
 <em>umask</em> (or <em>false</em>): Use permissions reported by umask(2). The default,
  when <tt>--shared</tt> is not specified.
 </p>
 </li>
 <li>
 <p>
 <em>group</em> (or <em>true</em>): Make the repository group-writable, (and g+sx, since
  the git group may be not the primary group of all users).
  This is used to loosen the permissions of an otherwise safe umask(2) value.
  Note that the umask still applies to the other permission bits (e.g. if
  umask is <em>0022</em>, using <em>group</em> will not remove read privileges from other
  (non-group) users). See <em>0xxx</em> for how to exactly specify the repository
  permissions.
 </p>
 </li>
 <li>
 <p>
 <em>all</em> (or <em>world</em> or <em>everybody</em>): Same as <em>group</em>, but make the repository
  readable by all users.
 </p>
 </li>
 <li>
 <p>
 <em>0xxx</em>: <em>0xxx</em> is an octal number and each file will have mode <em>0xxx</em>.
  <em>0xxx</em> will override users' umask(2) value (and not only loosen permissions
  as <em>group</em> and <em>all</em> does). <em>0640</em> will create a repository which is
  group-readable, but not group-writable or accessible to others. <em>0660</em> will
  create a repo that is readable and writable to the current user and group,
  but inaccessible to others.
 </p>
 </li>
 </ul></div>
 <div class="paragraph"><p>By default, the configuration flag receive.denyNonFastForwards is enabled
 in shared repositories, so that you cannot force a non fast-forwarding push
 into it.</p></div>
 <div class="paragraph"><p>If you name a (possibly non-existent) directory at the end of the command
 line, the command is run inside the directory (possibly after creating it).</p></div>
 </div>
 <h2 id="_description">DESCRIPTION</h2>
 <div class="sectionbody">
 <div class="paragraph"><p>This command creates an empty git repository - basically a <tt>.git</tt> directory
 with subdirectories for <tt>objects</tt>, <tt>refs/heads</tt>, <tt>refs/tags</tt>, and
 template files.
 An initial <tt>HEAD</tt> file that references the HEAD of the master branch
 is also created.</p></div>
 <div class="paragraph"><p>If the <tt>$GIT_DIR</tt> environment variable is set then it specifies a path
 to use instead of <tt>./.git</tt> for the base of the repository.</p></div>
 <div class="paragraph"><p>If the object storage directory is specified via the <tt>$GIT_OBJECT_DIRECTORY</tt>
 environment variable then the sha1 directories are created underneath -
 otherwise the default <tt>$GIT_DIR/objects</tt> directory is used.</p></div>
 <div class="paragraph"><p>Running <em>git init</em> in an existing repository is safe. It will not overwrite
 things that are already there. The primary reason for rerunning <em>git init</em>
 is to pick up newly added templates.</p></div>
 <div class="paragraph"><p>Note that <em>git init</em> is the same as <em>git init-db</em>. The command
 was primarily meant to initialize the object database, but over
 time it has become responsible for setting up the other aspects
 of the repository, such as installing the default hooks and
 setting the configuration variables. The old name is retained
 for backward compatibility reasons.</p></div>
 </div>
 <h2 id="_template_directory">TEMPLATE DIRECTORY</h2>
 <div class="sectionbody">
 <div class="paragraph"><p>The template directory contains files and directories that will be copied to
 the <tt>$GIT_DIR</tt> after it is created.</p></div>
 <div class="paragraph"><p>The template directory used will (in order):</p></div>
 <div class="ulist"><ul>
 <li>
 <p>
 The argument given with the <tt>--template</tt> option.
 </p>
 </li>
 <li>
 <p>
 The contents of the <tt>$GIT_TEMPLATE_DIR</tt> environment variable.
 </p>
 </li>
 <li>
 <p>
 The <tt>init.templatedir</tt> configuration variable.
 </p>
 </li>
 <li>
 <p>
 The default template directory: <tt>/usr/share/git-core/templates</tt>.
 </p>
 </li>
 </ul></div>
 <div class="paragraph"><p>The default template directory includes some directory structure, some
 suggested "exclude patterns", and copies of sample "hook" files.
 The suggested patterns and hook files are all modifiable and extensible.</p></div>

	<dd>
	<p>
	Specify that the git repository is to be shared amongst several users. This
	allows users belonging to the same group to push into that
	repository. When specified, the config variable "core.sharedRepository" is
	set so that files and directories under <tt>$GIT_DIR</tt> are created with the
	requested permissions. When not specified, git will use permissions reported
	by umask(2).
	</p>
	</dd>
	</dl></div>
	<div class="paragraph"><p>The option can have the following values, defaulting to <em>group</em> if no value
	is given:</p></div>
	<div class="ulist"><ul>
	<li>
	<p>
	<em>umask</em> (or <em>false</em>): Use permissions reported by umask(2). The default,
	when <tt>--shared</tt> is not specified.
	</p>
	</li>
	<li>
	<p>
	<em>group</em> (or <em>true</em>): Make the repository group-writable, (and g+sx, since
	the git group may be not the primary group of all users).
	This is used to loosen the permissions of an otherwise safe umask(2) value.
	Note that the umask still applies to the other permission bits (e.g. if
	umask is <em>0022</em>, using <em>group</em> will not remove read privileges from other
	(non-group) users). See <em>0xxx</em> for how to exactly specify the repository
	permissions.
	</p>
	</li>
	<li>
	<p>
	<em>all</em> (or <em>world</em> or <em>everybody</em>): Same as <em>group</em>, but make the repository
	readable by all users.
	</p>
	</li>
	<li>
	<p>
	<em>0xxx</em>: <em>0xxx</em> is an octal number and each file will have mode <em>0xxx</em>.
	<em>0xxx</em> will override users' umask(2) value (and not only loosen permissions
	as <em>group</em> and <em>all</em> does). <em>0640</em> will create a repository which is
	group-readable, but not group-writable or accessible to others. <em>0660</em> will
	create a repo that is readable and writable to the current user and group,
	but inaccessible to others.
	</p>
	</li>
	</ul></div>
	<div class="paragraph"><p>By default, the configuration flag receive.denyNonFastForwards is enabled
	in shared repositories, so that you cannot force a non fast-forwarding push
	into it.</p></div>
	<div class="paragraph"><p>If you name a (possibly non-existent) directory at the end of the command
	line, the command is run inside the directory (possibly after creating it).</p></div>
	</div>
	<h2 id="_description">DESCRIPTION</h2>
	<div class="sectionbody">
	<div class="paragraph"><p>This command creates an empty git repository - basically a <tt>.git</tt> directory
	with subdirectories for <tt>objects</tt>, <tt>refs/heads</tt>, <tt>refs/tags</tt>, and
	template files.
	An initial <tt>HEAD</tt> file that references the HEAD of the master branch
	is also created.</p></div>
	<div class="paragraph"><p>If the <tt>$GIT_DIR</tt> environment variable is set then it specifies a path
	to use instead of <tt>./.git</tt> for the base of the repository.</p></div>
	<div class="paragraph"><p>If the object storage directory is specified via the <tt>$GIT_OBJECT_DIRECTORY</tt>
	environment variable then the sha1 directories are created underneath -
	otherwise the default <tt>$GIT_DIR/objects</tt> directory is used.</p></div>
	<div class="paragraph"><p>Running <em>git init</em> in an existing repository is safe. It will not overwrite
	things that are already there. The primary reason for rerunning <em>git init</em>
	is to pick up newly added templates.</p></div>
	<div class="paragraph"><p>Note that <em>git init</em> is the same as <em>git init-db</em>. The command
	was primarily meant to initialize the object database, but over
	time it has become responsible for setting up the other aspects
	of the repository, such as installing the default hooks and
	setting the configuration variables. The old name is retained
	for backward compatibility reasons.</p></div>
	</div>
	<h2 id="_template_directory">TEMPLATE DIRECTORY</h2>
	<div class="sectionbody">
	<div class="paragraph"><p>The template directory contains files and directories that will be copied to
	the <tt>$GIT_DIR</tt> after it is created.</p></div>
	<div class="paragraph"><p>The template directory used will (in order):</p></div>
	<div class="ulist"><ul>
	<li>
	<p>
	The argument given with the <tt>--template</tt> option.
	</p>
	</li>
	<li>
	<p>
	The contents of the <tt>$GIT_TEMPLATE_DIR</tt> environment variable.
	</p>
	</li>
	<li>
	<p>
	The <tt>init.templatedir</tt> configuration variable.
	</p>
	</li>
	<li>
	<p>
	The default template directory: <tt>/usr/share/git-core/templates</tt>.

	<div class="paragraph"><p>The default template directory includes some directory structure, some
	suggested "exclude patterns", and copies of sample "hook" files.
