NAME
----
git-clone - Clones a repository


SYNOPSIS
--------
[verse]
'git-clone' [--template=<template_directory>] [-l [-s]] [-q] [-n] [--bare]
	  [-o <name>] [-u <upload-pack>] [--reference <repository>]
	  [--use-separate-remote] <repository> [<directory>]

DESCRIPTION
-----------
Clones a repository into a newly created directory.  All remote
branch heads are copied under `$GIT_DIR/refs/heads/`, except
that the remote `master` is also copied to `origin` branch.

In addition, `$GIT_DIR/remotes/origin` file is set up to have
this line:

	Pull: master:origin

This is to help the typical workflow of working off of the
remote `master` branch.  Every time `git pull` without argument
is run, the progress on the remote `master` branch is tracked by
copying it into the local `origin` branch, and merged into the
branch you are currently working on.  Remote branches other than
`master` are also added there to be tracked.


OPTIONS
-------
--local::
-l::
	When the repository to clone from is on a local machine,
	this flag bypasses normal "git aware" transport
	mechanism and clones the repository by making a copy of
	HEAD and everything under objects and refs directories.
	The files under .git/objects/ directory are hardlinked
	to save space when possible.

--shared::
-s::
	When the repository to clone is on the local machine,
	instead of using hard links, automatically setup
	.git/objects/info/alternates to share the objects
	with the source repository.  The resulting repository
	starts out without any object of its own.

--reference <repository>::
	If the reference repository is on the local machine
	automatically setup .git/objects/info/alternates to
	obtain objects from the reference repository.  Using
	an already existing repository as an alternate will
	require less objects to be copied from the repository
	being cloned, reducing network and local storage costs.

--quiet::
-q::
	Operate quietly.  This flag is passed to "rsync" and
	"git-fetch-pack" commands when given.

-n::
	No checkout of HEAD is performed after the clone is complete.

--bare::
	Make a 'bare' GIT repository.  That is, instead of
	creating `<directory>` and placing the administrative
	files in `<directory>/.git`, make the `<directory>`
	itself the `$GIT_DIR`. This implies `-n` option.  When
	this option is used, neither the `origin` branch nor the
	default `remotes/origin` file is created.

-o <name>::
	Instead of using the branch name 'origin' to keep track
	of the upstream repository, use <name> instead.  Note
	that the shorthand name stored in `remotes/origin` is
	not affected, but the local branch name to pull the
	remote `master` branch into is.

--upload-pack <upload-pack>::
-u <upload-pack>::
	When given, and the repository to clone from is handled
	by 'git-fetch-pack', '--exec=<upload-pack>' is passed to
	the command to specify non-default path for the command
	run on the other end.

--template=<template_directory>::
	Specify the directory from which templates will be used;
	if unset the templates are taken from the installation
	defined default, typically `/usr/share/git-core/templates`.

--use-separate-remote::
	Save remotes heads under `$GIT_DIR/remotes/origin/` instead
	of `$GIT_DIR/refs/heads/`.  Only the master branch is saved
	in the latter.

<repository>::
	The (possibly remote) repository to clone from.  It can
	be any URL git-fetch supports.

<directory>::
	The name of a new directory to clone into.  The "humanish"
	part of the source repository is used if no directory is
	explicitly given ("repo" for "/path/to/repo.git" and "foo"
	for "host.xz:foo/.git").  Cloning into an existing directory
	is not allowed.

Examples
--------

Clone from upstream::
+
------------
$ git clone git://git.kernel.org/pub/scm/.../linux-2.6 my2.6
$ cd my2.6
$ make
------------


Make a local clone that borrows from the current directory, without checking things out::
+
------------
$ git clone -l -s -n . ../copy
$ cd copy
$ git show-branch
------------


Clone from upstream while borrowing from an existing local directory::
+
------------
$ git clone --reference my2.6 \
	git://git.kernel.org/pub/scm/.../linux-2.7 \
	my2.7
$ cd my2.7
------------


Create a bare repository to publish your changes to the public::
+
------------
$ git clone --bare -l /home/proj/.git /pub/scm/proj.git
------------


Create a repository on the kernel.org machine that borrows from Linus::
+
------------
$ git clone --bare -l -s /pub/scm/.../torvalds/linux-2.6.git \
    /pub/scm/.../me/subsys-2.6.git
------------
