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>] [-u <upload-pack>] [--reference <repository>]
15 [--depth <depth>] [--] <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 initial
23 branch equal to the cloned repository's currently active branch.
25 After the clone, a plain `git fetch` without arguments will update
26 all the remote-tracking branches, and a `git pull` without
27 arguments will in addition merge the remote master branch into the
28 current master branch, if any.
30 This default configuration is achieved by creating references to
31 the remote branch heads under `$GIT_DIR/refs/remotes/origin` and
32 by initializing `remote.origin.url` and `remote.origin.fetch`
33 configuration variables.
40 When the repository to clone from is on a local machine,
41 this flag bypasses normal "git aware" transport
42 mechanism and clones the repository by making a copy of
43 HEAD and everything under objects and refs directories.
44 The files under `.git/objects/` directory are hardlinked
45 to save space when possible. This is now the default when
46 the source repository is specified with `/path/to/repo`
47 syntax, so it essentially is a no-op option. To force
48 copying instead of hardlinking (which may be desirable
49 if you are trying to make a back-up of your repository),
50 but still avoid the usual "git aware" transport
51 mechanism, `--no-hardlinks` can be used.
54 Optimize the cloning process from a repository on a
55 local filesystem by copying files under `.git/objects`
60 When the repository to clone is on the local machine,
61 instead of using hard links, automatically setup
62 .git/objects/info/alternates to share the objects
63 with the source repository. The resulting repository
64 starts out without any object of its own.
66 *NOTE*: this is a possibly dangerous operation; do *not* use
67 it unless you understand what it does. If you clone your
68 repository using this option and then delete branches (or use any
69 other git command that makes any existing commit unreferenced) in the
70 source repository, some objects may become unreferenced (or dangling).
71 These objects may be removed by normal git operations (such as 'git-commit')
72 which automatically call `git gc --auto`. (See linkgit:git-gc[1].)
73 If these objects are removed and were referenced by the cloned repository,
74 then the cloned repository will become corrupt.
78 --reference <repository>::
79 If the reference repository is on the local machine
80 automatically setup .git/objects/info/alternates to
81 obtain objects from the reference repository. Using
82 an already existing repository as an alternate will
83 require fewer objects to be copied from the repository
84 being cloned, reducing network and local storage costs.
86 *NOTE*: see NOTE to --shared option.
90 Operate quietly. This flag is also passed to the `rsync'
95 Display the progressbar, even in case the standard output is not
100 No checkout of HEAD is performed after the clone is complete.
103 Make a 'bare' GIT repository. That is, instead of
104 creating `<directory>` and placing the administrative
105 files in `<directory>/.git`, make the `<directory>`
106 itself the `$GIT_DIR`. This obviously implies the `-n`
107 because there is nowhere to check out the working tree.
108 Also the branch heads at the remote are copied directly
109 to corresponding local branch heads, without mapping
110 them to `refs/remotes/origin/`. When this option is
111 used, neither remote-tracking branches nor the related
112 configuration variables are created.
115 Set up a mirror of the remote repository. This implies --bare.
119 Instead of using the remote name 'origin' to keep track
120 of the upstream repository, use <name> instead.
122 --upload-pack <upload-pack>::
124 When given, and the repository to clone from is accessed
125 via ssh, this specifies a non-default path for the command
126 run on the other end.
128 --template=<template_directory>::
129 Specify the directory from which templates will be used;
130 if unset the templates are taken from the installation
131 defined default, typically `/usr/share/git-core/templates`.
134 Create a 'shallow' clone with a history truncated to the
135 specified number of revisions. A shallow repository has a
136 number of limitations (you cannot clone or fetch from
137 it, nor push from nor into it), but is adequate if you
138 are only interested in the recent history of a large project
139 with a long history, and would want to send in fixes
143 The (possibly remote) repository to clone from. See the
144 <<URLS,URLS>> section below for more information on specifying
148 The name of a new directory to clone into. The "humanish"
149 part of the source repository is used if no directory is
150 explicitly given ("repo" for "/path/to/repo.git" and "foo"
151 for "host.xz:foo/.git"). Cloning into an existing directory
160 Clone from upstream::
163 $ git clone git://git.kernel.org/pub/scm/.../linux-2.6 my2.6
169 Make a local clone that borrows from the current directory, without checking things out::
172 $ git clone -l -s -n . ../copy
178 Clone from upstream while borrowing from an existing local directory::
181 $ git clone --reference my2.6 \
182 git://git.kernel.org/pub/scm/.../linux-2.7 \
188 Create a bare repository to publish your changes to the public::
191 $ git clone --bare -l /home/proj/.git /pub/scm/proj.git
195 Create a repository on the kernel.org machine that borrows from Linus::
198 $ git clone --bare -l -s /pub/scm/.../torvalds/linux-2.6.git \
199 /pub/scm/.../me/subsys-2.6.git
