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|--recurse-submodules] [--] <repository>
21 Clones a repository into a newly created directory, creates
22 remote-tracking branches for each branch in the cloned repository
23 (visible using `git branch -r`), and creates and checks out an
24 initial branch that is forked from the cloned repository's
25 currently active branch.
27 After the clone, a plain `git fetch` without arguments will update
28 all the remote-tracking branches, and a `git pull` without
29 arguments will in addition merge the remote master branch into the
30 current master branch, if any.
32 This default configuration is achieved by creating references to
33 the remote branch heads under `refs/remotes/origin` and
34 by initializing `remote.origin.url` and `remote.origin.fetch`
35 configuration variables.
42 When the repository to clone from is on a local machine,
43 this flag bypasses the normal "git aware" transport
44 mechanism and clones the repository by making a copy of
45 HEAD and everything under objects and refs directories.
46 The files under `.git/objects/` directory are hardlinked
47 to save space when possible. This is now the default when
48 the source repository is specified with `/path/to/repo`
49 syntax, so it essentially is a no-op option. To force
50 copying instead of hardlinking (which may be desirable
51 if you are trying to make a back-up of your repository),
52 but still avoid the usual "git aware" transport
53 mechanism, `--no-hardlinks` can be used.
56 Optimize the cloning process from a repository on a
57 local filesystem by copying files under `.git/objects`
62 When the repository to clone is on the local machine,
63 instead of using hard links, automatically setup
64 `.git/objects/info/alternates` to share the objects
65 with the source repository. The resulting repository
66 starts out without any object of its own.
68 *NOTE*: this is a possibly dangerous operation; do *not* use
69 it unless you understand what it does. If you clone your
70 repository using this option and then delete branches (or use any
71 other git command that makes any existing commit unreferenced) in the
72 source repository, some objects may become unreferenced (or dangling).
73 These objects may be removed by normal git operations (such as `git commit`)
74 which automatically call `git gc --auto`. (See linkgit:git-gc[1].)
75 If these objects are removed and were referenced by the cloned repository,
76 then the cloned repository will become corrupt.
78 Note that running `git repack` without the `-l` option in a repository
79 cloned with `-s` will copy objects from the source repository into a pack
80 in the cloned repository, removing the disk space savings of `clone -s`.
81 It is safe, however, to run `git gc`, which uses the `-l` option by
84 If you want to break the dependency of a repository cloned with `-s` on
85 its source repository, you can simply run `git repack -a` to copy all
86 objects from the source repository into a pack in the cloned repository.
88 --reference <repository>::
89 If the reference repository is on the local machine,
90 automatically setup `.git/objects/info/alternates` to
91 obtain objects from the reference repository. Using
92 an already existing repository as an alternate will
93 require fewer objects to be copied from the repository
94 being cloned, reducing network and local storage costs.
96 *NOTE*: see the NOTE for the `--shared` option.
100 Operate quietly. Progress is not reported to the standard
101 error stream. This flag is also passed to the `rsync'
106 Run verbosely. Does not affect the reporting of progress status
107 to the standard error stream.
110 Progress status is reported on the standard error stream
111 by default when it is attached to a terminal, unless -q
112 is specified. This flag forces progress status even if the
113 standard error stream is not directed to a terminal.
117 No checkout of HEAD is performed after the clone is complete.
120 Make a 'bare' GIT repository. That is, instead of
121 creating `<directory>` and placing the administrative
122 files in `<directory>/.git`, make the `<directory>`
123 itself the `$GIT_DIR`. This obviously implies the `-n`
124 because there is nowhere to check out the working tree.
125 Also the branch heads at the remote are copied directly
126 to corresponding local branch heads, without mapping
127 them to `refs/remotes/origin/`. When this option is
128 used, neither remote-tracking branches nor the related
129 configuration variables are created.
132 Set up a mirror of the source repository. This implies `--bare`.
133 Compared to `--bare`, `--mirror` not only maps local branches of the
134 source to local branches of the target, it maps all refs (including
135 remote-tracking branches, notes etc.) and sets up a refspec configuration such
136 that all these refs are overwritten by a `git remote update` in the
141 Instead of using the remote name `origin` to keep track
142 of the upstream repository, use `<name>`.
146 Instead of pointing the newly created HEAD to the branch pointed
147 to by the cloned repository's HEAD, point to `<name>` branch
148 instead. In a non-bare repository, this is the branch that will
151 --upload-pack <upload-pack>::
153 When given, and the repository to clone from is accessed
154 via ssh, this specifies a non-default path for the command
155 run on the other end.
157 --template=<template_directory>::
158 Specify the directory from which templates will be used;
159 (See the "TEMPLATE DIRECTORY" section of linkgit:git-init[1].)
162 Create a 'shallow' clone with a history truncated to the
163 specified number of revisions. A shallow repository has a
164 number of limitations (you cannot clone or fetch from
165 it, nor push from nor into it), but is adequate if you
166 are only interested in the recent history of a large project
167 with a long history, and would want to send in fixes
171 --recurse-submodules::
172 After the clone is created, initialize all submodules within,
173 using their default settings. This is equivalent to running
174 `git submodule update --init --recursive` immediately after
175 the clone is finished. This option is ignored if the cloned
176 repository does not have a worktree/checkout (i.e. if any of
177 `--no-checkout`/`-n`, `--bare`, or `--mirror` is given)
180 The (possibly remote) repository to clone from. See the
181 <<URLS,URLS>> section below for more information on specifying
185 The name of a new directory to clone into. The "humanish"
186 part of the source repository is used if no directory is
187 explicitly given (`repo` for `/path/to/repo.git` and `foo`
188 for `host.xz:foo/.git`). Cloning into an existing directory
189 is only allowed if the directory is empty.
197 * Clone from upstream:
200 $ git clone git://git.kernel.org/pub/scm/.../linux-2.6 my2.6
206 * Make a local clone that borrows from the current directory, without checking things out:
209 $ git clone -l -s -n . ../copy
215 * Clone from upstream while borrowing from an existing local directory:
218 $ git clone --reference my2.6 \
219 git://git.kernel.org/pub/scm/.../linux-2.7 \
225 * Create a bare repository to publish your changes to the public:
228 $ git clone --bare -l /home/proj/.git /pub/scm/proj.git
232 * Create a repository on the kernel.org machine that borrows from Linus:
235 $ git clone --bare -l -s /pub/scm/.../torvalds/linux-2.6.git \
236 /pub/scm/.../me/subsys-2.6.git
