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. Progress is not reported to the standard
100 error stream. This flag is also passed to the `rsync'
108 Progress status is reported on the standard error stream
109 by default when it is attached to a terminal, unless -q
110 is specified. This flag forces progress status even if the
111 standard error stream is not directed to a terminal.
115 No checkout of HEAD is performed after the clone is complete.
118 Make a 'bare' GIT repository. That is, instead of
119 creating `<directory>` and placing the administrative
120 files in `<directory>/.git`, make the `<directory>`
121 itself the `$GIT_DIR`. This obviously implies the `-n`
122 because there is nowhere to check out the working tree.
123 Also the branch heads at the remote are copied directly
124 to corresponding local branch heads, without mapping
125 them to `refs/remotes/origin/`. When this option is
126 used, neither remote-tracking branches nor the related
127 configuration variables are created.
130 Set up a mirror of the remote repository. This implies `--bare`.
134 Instead of using the remote name `origin` to keep track
135 of the upstream repository, use `<name>`.
139 Instead of pointing the newly created HEAD to the branch pointed
140 to by the cloned repository's HEAD, point to `<name>` branch
141 instead. In a non-bare repository, this is the branch that will
144 --upload-pack <upload-pack>::
146 When given, and the repository to clone from is accessed
147 via ssh, this specifies a non-default path for the command
148 run on the other end.
150 --template=<template_directory>::
151 Specify the directory from which templates will be used;
152 if unset the templates are taken from the installation
153 defined default, typically `/usr/share/git-core/templates`.
156 Create a 'shallow' clone with a history truncated to the
157 specified number of revisions. A shallow repository has a
158 number of limitations (you cannot clone or fetch from
159 it, nor push from nor into it), but is adequate if you
160 are only interested in the recent history of a large project
161 with a long history, and would want to send in fixes
165 After the clone is created, initialize all submodules within,
166 using their default settings. This is equivalent to running
167 `git submodule update --init --recursive` immediately after
168 the clone is finished. This option is ignored if the cloned
169 repository does not have a worktree/checkout (i.e. if any of
170 `--no-checkout`/`-n`, `--bare`, or `--mirror` is given)
173 The (possibly remote) repository to clone from. See the
174 <<URLS,URLS>> section below for more information on specifying
178 The name of a new directory to clone into. The "humanish"
179 part of the source repository is used if no directory is
180 explicitly given (`repo` for `/path/to/repo.git` and `foo`
181 for `host.xz:foo/.git`). Cloning into an existing directory
182 is only allowed if the directory is empty.
190 Clone from upstream::
193 $ git clone git://git.kernel.org/pub/scm/.../linux-2.6 my2.6
199 Make a local clone that borrows from the current directory, without checking things out::
202 $ git clone -l -s -n . ../copy
208 Clone from upstream while borrowing from an existing local directory::
211 $ git clone --reference my2.6 \
212 git://git.kernel.org/pub/scm/.../linux-2.7 \
218 Create a bare repository to publish your changes to the public::
221 $ git clone --bare -l /home/proj/.git /pub/scm/proj.git
225 Create a repository on the kernel.org machine that borrows from Linus::
228 $ git clone --bare -l -s /pub/scm/.../torvalds/linux-2.6.git \
229 /pub/scm/.../me/subsys-2.6.git
