<h2 id="_description">DESCRIPTION</h2>
<div class="sectionbody">
<div class="paragraph"><p>Clones a repository into a newly created directory, creates
remote-tracking branches for each branch in the cloned repository
(visible using <code>git branch --remotes</code>), and creates and checks out an
initial branch that is forked from the cloned repository’s
currently active branch.</p></div>
<div class="paragraph"><p>After the clone, a plain <code>git fetch</code> without arguments will update
all the remote-tracking branches, and a <code>git pull</code> without
arguments will in addition merge the remote master branch into the
current master branch, if any (this is untrue when <code>--single-branch</code>
is given; see below).</p></div>
<div class="paragraph"><p>This default configuration is achieved by creating references to
the remote branch heads under <code>refs/remotes/origin</code> and
by initializing <code>remote.origin.url</code> and <code>remote.origin.fetch</code>
configuration variables.</p></div>
</div>
</div>
<div class="sect1">
<h2 id="_options">OPTIONS</h2>
<div class="sectionbody">
<div class="dlist"><dl>
<dt class="hdlist1">
<code>-l</code>
</dt>
<dt class="hdlist1">
<code>--local</code>
</dt>
<dd>
<p>
When the repository to clone from is on a local machine,
this flag bypasses the normal "Git aware" transport
mechanism and clones the repository by making a copy of
<code>HEAD</code> and everything under objects and refs directories.
The files under <code>.git/objects/</code> directory are hardlinked
to save space when possible.
</p>
<div class="paragraph"><p>If the repository is specified as a local path (e.g., <code>/path/to/repo</code>),
this is the default, and --local is essentially a no-op. If the
repository is specified as a URL, then this flag is ignored (and we
never use the local optimizations). Specifying <code>--no-local</code> will
override the default when <code>/path/to/repo</code> is given, using the regular
Git transport instead.</p></div>
<div class="paragraph"><p>If the repository’s <code>$GIT_DIR/objects</code> has symbolic links or is a
symbolic link, the clone will fail. This is a security measure to
prevent the unintentional copying of files by dereferencing the symbolic
links.</p></div>
<div class="paragraph"><p><strong>NOTE</strong>: this operation can race with concurrent modification to the
source repository, similar to running <code>cp -r src dst</code> while modifying
<code>src</code>.</p></div>
</dd>
<dt class="hdlist1">
<code>--no-hardlinks</code>
</dt>
<dd>
<p>
Force the cloning process from a repository on a local
filesystem to copy the files under the <code>.git/objects</code>
directory instead of using hardlinks. This may be desirable
if you are trying to make a back-up of your repository.
</p>
</dd>
<dt class="hdlist1">
<code>-s</code>
</dt>
<dt class="hdlist1">
<code>--shared</code>
</dt>
<dd>
<p>
When the repository to clone is on the local machine,
instead of using hard links, automatically setup
<code>.git/objects/info/alternates</code> to share the objects
with the source repository. The resulting repository
starts out without any object of its own.
</p>
<div class="paragraph"><p><strong>NOTE</strong>: this is a possibly dangerous operation; do <strong>not</strong> use
it unless you understand what it does. If you clone your
repository using this option and then delete branches (or use any
other Git command that makes any existing commit unreferenced) in the
source repository, some objects may become unreferenced (or dangling).
These objects may be removed by normal Git operations (such as <code>git commit</code>)
which automatically call <code>git maintenance run --auto</code>. (See
<a href="git-maintenance.html">git-maintenance(1)</a>.) If these objects are removed and were referenced
by the cloned repository, then the cloned repository will become corrupt.</p></div>
<div class="paragraph"><p>Note that running <code>git repack</code> without the <code>--local</code> option in a repository
cloned with <code>--shared</code> will copy objects from the source repository into a pack
in the cloned repository, removing the disk space savings of <code>clone --shared</code>.
It is safe, however, to run <code>git gc</code>, which uses the <code>--local</code> option by
default.</p></div>
<div class="paragraph"><p>If you want to break the dependency of a repository cloned with <code>--shared</code> on
its source repository, you can simply run <code>git repack -a</code> to copy all
objects from the source repository into a pack in the cloned repository.</p></div>
</dd>
<dt class="hdlist1">
<code>--reference</code>[<code>-if-able</code>] <em><repository></em>
</dt>
<dd>
<p>
If the reference <em><repository></em> is on the local machine,
automatically setup <code>.git/objects/info/alternates</code> to
obtain objects from the reference <em><repository></em>. Using
an already existing repository as an alternate will
require fewer objects to be copied from the repository
being cloned, reducing network and local storage costs.
When using the <code>--reference-if-able</code>, a non existing
directory is skipped with a warning instead of aborting
the clone.
</p>
<div class="paragraph"><p><strong>NOTE</strong>: see the NOTE for the <code>--shared</code> option, and also the
<code>--dissociate</code> option.</p></div>
</dd>
<dt class="hdlist1">
<code>--dissociate</code>
</dt>
<dd>
<p>
Borrow the objects from reference repositories specified
with the <code>--reference</code> options only to reduce network
transfer, and stop borrowing from them after a clone is made
by making necessary local copies of borrowed objects. This
option can also be used when cloning locally from a
repository that already borrows objects from another
repository—the new repository will borrow objects from the
same repository, and this option can be used to stop the
borrowing.
</p>
</dd>
<dt class="hdlist1">
<code>-q</code>
</dt>
<dt class="hdlist1">
<code>--quiet</code>
</dt>
<dd>
<p>
Operate quietly. Progress is not reported to the standard
error stream.
</p>
</dd>
<dt class="hdlist1">
<code>-v</code>
</dt>
<dt class="hdlist1">
<code>--verbose</code>
</dt>
<dd>
<p>
Run verbosely. Does not affect the reporting of progress status
to the standard error stream.
</p>
</dd>
<dt class="hdlist1">
<code>--progress</code>
</dt>
<dd>
<p>
Progress status is reported on the standard error stream
by default when it is attached to a terminal, unless <code>--quiet</code>
is specified. This flag forces progress status even if the
standard error stream is not directed to a terminal.
</p>
</dd>
<dt class="hdlist1">
<code>--server-option=</code><em><option></em>
</dt>
<dd>
<p>
Transmit the given string to the server when communicating using
protocol version 2. The given string must not contain a NUL or LF
character. The server’s handling of server options, including
unknown ones, is server-specific.
When multiple <code>--server-option=</code><em><option></em> are given, they are all
sent to the other side in the order listed on the command line.
</p>
</dd>
<dt class="hdlist1">
<code>-n</code>
</dt>
<dt class="hdlist1">
<code>--no-checkout</code>
</dt>
<dd>
<p>
No checkout of HEAD is performed after the clone is complete.
</p>
</dd>
<dt class="hdlist1">
<code>--</code>[<code>no-</code>]<code>reject-shallow</code>
</dt>
<dd>
<p>
Fail if the source repository is a shallow repository.
The <code>clone.rejectShallow</code> configuration variable can be used to
specify the default.
</p>
</dd>
<dt class="hdlist1">
<code>--bare</code>
</dt>
<dd>
<p>
Make a <em>bare</em> Git repository. That is, instead of
creating <em><directory></em> and placing the administrative
files in <em><directory></em><code>/.git</code>, make the <em><directory></em>
itself the <code>$GIT_DIR</code>. This obviously implies the <code>--no-checkout</code>
because there is nowhere to check out the working tree.
Also the branch heads at the remote are copied directly
to corresponding local branch heads, without mapping
them to <code>refs/remotes/origin/</code>. When this option is
used, neither remote-tracking branches nor the related
configuration variables are created.
</p>
</dd>
<dt class="hdlist1">
<code>--sparse</code>
</dt>
<dd>
<p>
Employ a sparse-checkout, with only files in the toplevel
directory initially being present. The
<a href="git-sparse-checkout.html">git-sparse-checkout(1)</a> command can be used to grow the
working directory as needed.
</p>
</dd>
<dt class="hdlist1">
<code>--filter=</code><em><filter-spec></em>
</dt>
<dd>
<p>
Use the partial clone feature and request that the server sends
a subset of reachable objects according to a given object filter.
When using <code>--filter</code>, the supplied <em><filter-spec></em> is used for
the partial clone filter. For example, <code>--filter=blob:none</code> will
filter out all blobs (file contents) until needed by Git. Also,
