6 git-clone - Clone a repository into a new directory
12 'git clone' [--template=<template_directory>]
13 [-l] [-s] [--no-hardlinks] [-q] [-n] [--bare] [--mirror]
14 [-o <name>] [-b <name>] [-u <upload-pack>] [--reference <repository>]
15 [--depth <depth>] [--recursive] [--] <repository> [<directory>]
20 Clones a repository into a newly created directory, creates
21 remote-tracking branches for each branch in the cloned repository
22 (visible using `git branch -r`), and creates and checks out an
23 initial branch that is forked from the cloned repository's
24 currently active branch.
26 After the clone, a plain `git fetch` without arguments will update
27 all the remote-tracking branches, and a `git pull` without
28 arguments will in addition merge the remote master branch into the
29 current master branch, if any.
31 This default configuration is achieved by creating references to
32 the remote branch heads under `$GIT_DIR/refs/remotes/origin` and
33 by initializing `remote.origin.url` and `remote.origin.fetch`
34 configuration variables.
41 When the repository to clone from is on a local machine,
42 this flag bypasses the normal "git aware" transport
43 mechanism and clones the repository by making a copy of
44 HEAD and everything under objects and refs directories.
45 The files under `.git/objects/` directory are hardlinked
46 to save space when possible. This is now the default when
47 the source repository is specified with `/path/to/repo`
48 syntax, so it essentially is a no-op option. To force
49 copying instead of hardlinking (which may be desirable
50 if you are trying to make a back-up of your repository),
51 but still avoid the usual "git aware" transport
52 mechanism, `--no-hardlinks` can be used.
55 Optimize the cloning process from a repository on a
56 local filesystem by copying files under `.git/objects`
61 When the repository to clone is on the local machine,
62 instead of using hard links, automatically setup
63 `.git/objects/info/alternates` to share the objects
64 with the source repository. The resulting repository
65 starts out without any object of its own.
67 *NOTE*: this is a possibly dangerous operation; do *not* use
68 it unless you understand what it does. If you clone your
69 repository using this option and then delete branches (or use any
70 other git command that makes any existing commit unreferenced) in the
71 source repository, some objects may become unreferenced (or dangling).
72 These objects may be removed by normal git operations (such as `git commit`)
73 which automatically call `git gc --auto`. (See linkgit:git-gc[1].)
74 If these objects are removed and were referenced by the cloned repository,
75 then the cloned repository will become corrupt.
77 Note that running `git repack` without the `-l` option in a repository
78 cloned with `-s` will copy objects from the source repository into a pack
79 in the cloned repository, removing the disk space savings of `clone -s`.
80 It is safe, however, to run `git gc`, which uses the `-l` option by
83 If you want to break the dependency of a repository cloned with `-s` on
84 its source repository, you can simply run `git repack -a` to copy all
85 objects from the source repository into a pack in the cloned repository.
87 --reference <repository>::
88 If the reference repository is on the local machine,
89 automatically setup `.git/objects/info/alternates` to
90 obtain objects from the reference repository. Using
91 an already existing repository as an alternate will
92 require fewer objects to be copied from the repository
93 being cloned, reducing network and local storage costs.
95 *NOTE*: see the NOTE for the `--shared` option.
99 Operate quietly. This flag is also passed to the `rsync'
104 Display the progress bar, even in case the standard output is not
109 No checkout of HEAD is performed after the clone is complete.
112 Make a 'bare' GIT repository. That is, instead of
113 creating `<directory>` and placing the administrative
114 files in `<directory>/.git`, make the `<directory>`
115 itself the `$GIT_DIR`. This obviously implies the `-n`
116 because there is nowhere to check out the working tree.
117 Also the branch heads at the remote are copied directly
118 to corresponding local branch heads, without mapping
119 them to `refs/remotes/origin/`. When this option is
120 used, neither remote-tracking branches nor the related
121 configuration variables are created.
124 Set up a mirror of the remote repository. This implies `--bare`.
128 Instead of using the remote name `origin` to keep track
129 of the upstream repository, use `<name>`.
133 Instead of pointing the newly created HEAD to the branch pointed
134 to by the cloned repository's HEAD, point to `<name>` branch
135 instead. In a non-bare repository, this is the branch that will
138 --upload-pack <upload-pack>::
140 When given, and the repository to clone from is accessed
141 via ssh, this specifies a non-default path for the command
142 run on the other end.
144 --template=<template_directory>::
145 Specify the directory from which templates will be used;
146 if unset the templates are taken from the installation
147 defined default, typically `/usr/share/git-core/templates`.
150 Create a 'shallow' clone with a history truncated to the
151 specified number of revisions. A shallow repository has a
152 number of limitations (you cannot clone or fetch from
153 it, nor push from nor into it), but is adequate if you
154 are only interested in the recent history of a large project
155 with a long history, and would want to send in fixes
159 After the clone is created, initialize all submodules within,
160 using their default settings. This is equivalent to running
161 `git submodule update --init --recursive` immediately after
162 the clone is finished. This option is ignored if the cloned
163 repository does not have a worktree/checkout (i.e. if any of
164 `--no-checkout`/`-n`, `--bare`, or `--mirror` is given)
167 The (possibly remote) repository to clone from. See the
168 <<URLS,URLS>> section below for more information on specifying
172 The name of a new directory to clone into. The "humanish"
173 part of the source repository is used if no directory is
174 explicitly given (`repo` for `/path/to/repo.git` and `foo`
175 for `host.xz:foo/.git`). Cloning into an existing directory
176 is only allowed if the directory is empty.
184 Clone from upstream::
187 $ git clone git://git.kernel.org/pub/scm/.../linux-2.6 my2.6
193 Make a local clone that borrows from the current directory, without checking things out::
196 $ git clone -l -s -n . ../copy
202 Clone from upstream while borrowing from an existing local directory::
205 $ git clone --reference my2.6 \
206 git://git.kernel.org/pub/scm/.../linux-2.7 \
212 Create a bare repository to publish your changes to the public::
215 $ git clone --bare -l /home/proj/.git /pub/scm/proj.git
219 Create a repository on the kernel.org machine that borrows from Linus::
222 $ git clone --bare -l -s /pub/scm/.../torvalds/linux-2.6.git \
223 /pub/scm/.../me/subsys-2.6.git
