20 | DESCRIPTION | |
21 | ----------- | |
4607166d | 22 | |
db9819a4 BF |
23 | Clones a repository into a newly created directory, creates |
24 | remote-tracking branches for each branch in the cloned repository | |
33405be3 JN |
25 | (visible using `git branch -r`), and creates and checks out an |
26 | initial branch that is forked from the cloned repository's | |
27 | currently active branch. | |
4607166d | 28 | |
db9819a4 BF |
29 | After the clone, a plain `git fetch` without arguments will update |
30 | all the remote-tracking branches, and a `git pull` without | |
31 | arguments will in addition merge the remote master branch into the | |
1170e802 | 32 | current master branch, if any. |
4607166d | 33 | |
db9819a4 | 34 | This default configuration is achieved by creating references to |
cc1b8d8b | 35 | the remote branch heads under `refs/remotes/origin` and |
db9819a4 BF |
36 | by initializing `remote.origin.url` and `remote.origin.fetch` |
37 | configuration variables. | |

40 | OPTIONS |
41 | ------- | |
a2775c2a | 42 | --local:: |
6ec311da JH |
43 | -l:: |
44 | When the repository to clone from is on a local machine, | |
550c66f3 | 45 | this flag bypasses the normal "git aware" transport |
6ec311da JH |
46 | mechanism and clones the repository by making a copy of |
47 | HEAD and everything under objects and refs directories. | |
3d5c418f | 48 | The files under `.git/objects/` directory are hardlinked |
9197a10c JK |
49 | to save space when possible. |
50 | + | |
51 | If the repository is specified as a local path (e.g., `/path/to/repo`), | |
52 | this is the default, and --local is essentially a no-op. If the | |
53 | repository is specified as a URL, then this flag is ignored (and we | |
189260b1 JK |
54 | never use the local optimizations). Specifying `--no-local` will |
55 | override the default when `/path/to/repo` is given, using the regular | |
56 | git transport instead. | |
9197a10c JK |
57 | + |
58 | To force copying instead of hardlinking (which may be desirable if you | |
59 | are trying to make a back-up of your repository), but still avoid the | |
60 | usual "git aware" transport mechanism, `--no-hardlinks` can be used. | |
3d5c418f JH |
61 | |
62 | --no-hardlinks:: | |
63 | Optimize the cloning process from a repository on a | |
64 | local filesystem by copying files under `.git/objects` | |
65 | directory. | |
6ec311da | 66 | |
a2775c2a EB |
67 | --shared:: |
68 | -s:: | |
69 | When the repository to clone is on the local machine, | |
4607166d | 70 | instead of using hard links, automatically setup |
550c66f3 | 71 | `.git/objects/info/alternates` to share the objects |
4607166d JH |
72 | with the source repository. The resulting repository |
73 | starts out without any object of its own. | |
84668872 MV |
74 | + |
75 | *NOTE*: this is a possibly dangerous operation; do *not* use | |
76 | it unless you understand what it does. If you clone your | |
2498a1ad BC |
77 | repository using this option and then delete branches (or use any |
78 | other git command that makes any existing commit unreferenced) in the | |
79 | source repository, some objects may become unreferenced (or dangling). | |
550c66f3 | 80 | These objects may be removed by normal git operations (such as `git commit`) |
483bc4f0 JN |
81 | which automatically call `git gc --auto`. (See linkgit:git-gc[1].) |
82 | If these objects are removed and were referenced by the cloned repository, | |
83 | then the cloned repository will become corrupt. | |
13354f53 JK |
84 | + |
85 | Note that running `git repack` without the `-l` option in a repository | |
86 | cloned with `-s` will copy objects from the source repository into a pack | |
87 | in the cloned repository, removing the disk space savings of `clone -s`. | |
88 | It is safe, however, to run `git gc`, which uses the `-l` option by | |
89 | default. | |
90 | + | |
91 | If you want to break the dependency of a repository cloned with `-s` on | |
92 | its source repository, you can simply run `git repack -a` to copy all | |
93 | objects from the source repository into a pack in the cloned repository. | |
a2775c2a | 94 | |
23edecbc | 95 | --reference <repository>:: |
40592376 | 96 | If the reference repository is on the local machine, |
550c66f3 | 97 | automatically setup `.git/objects/info/alternates` to |
23edecbc SP |
98 | obtain objects from the reference repository. Using |
99 | an already existing repository as an alternate will | |
451e5931 | 100 | require fewer objects to be copied from the repository |
23edecbc | 101 | being cloned, reducing network and local storage costs. |
2498a1ad | 102 | + |
550c66f3 | 103 | *NOTE*: see the NOTE for the `--shared` option. |
23edecbc | 104 | |
a2775c2a | 105 | --quiet:: |
6ec311da | 106 | -q:: |
488c3163 TRC |
107 | Operate quietly. Progress is not reported to the standard |
108 | error stream. This flag is also passed to the `rsync' | |
d3296e37 | 109 | command when given. |
6ec311da | 110 | |
21188b1e MV |
111 | --verbose:: |
112 | -v:: | |
c54b74af TRC |
113 | Run verbosely. Does not affect the reporting of progress status |
114 | to the standard error stream. | |
5a518ad4 TRC |
115 | |
116 | --progress:: | |
488c3163 TRC |
117 | Progress status is reported on the standard error stream |
118 | by default when it is attached to a terminal, unless -q | |
119 | is specified. This flag forces progress status even if the | |
120 | standard error stream is not directed to a terminal. | |
21188b1e | 121 | |
fd0368f9 | 122 | --no-checkout:: |
a2775c2a EB |
123 | -n:: |
124 | No checkout of HEAD is performed after the clone is complete. | |
125 | ||
87e80c4b JH |
126 | --bare:: |
127 | Make a 'bare' GIT repository. That is, instead of | |
8a1a120c JH |
128 | creating `<directory>` and placing the administrative |
129 | files in `<directory>/.git`, make the `<directory>` | |
71821351 PB |
130 | itself the `$GIT_DIR`. This obviously implies the `-n` |
131 | because there is nowhere to check out the working tree. | |
132 | Also the branch heads at the remote are copied directly | |
133 | to corresponding local branch heads, without mapping | |
134 | them to `refs/remotes/origin/`. When this option is | |
36566cc0 BF |
135 | used, neither remote-tracking branches nor the related |
136 | configuration variables are created. | |
8a1a120c | 137 | |
bc699afc | 138 | --mirror:: |
6db2103f UKK |
139 | Set up a mirror of the source repository. This implies `--bare`. |
140 | Compared to `--bare`, `--mirror` not only maps local branches of the | |
141 | source to local branches of the target, it maps all refs (including | |
29b9a66f | 142 | remote-tracking branches, notes etc.) and sets up a refspec configuration such |
6db2103f UKK |
143 | that all these refs are overwritten by a `git remote update` in the |
144 | target repository. | |
bc699afc | 145 | |
ba158a32 | 146 | --origin <name>:: |
e6c310fd | 147 | -o <name>:: |
550c66f3 BG |
148 | Instead of using the remote name `origin` to keep track |
149 | of the upstream repository, use `<name>`. | |
e6c310fd | 150 | |
7a4ee28f JK |
151 | --branch <name>:: |
152 | -b <name>:: | |
153 | Instead of pointing the newly created HEAD to the branch pointed | |
550c66f3 | 154 | to by the cloned repository's HEAD, point to `<name>` branch |
5a7d5b68 NTND |
155 | instead. `--branch` can also take tags and treat them like |
156 | detached HEAD. In a non-bare repository, this is the branch | |
157 | that will be checked out. | |
7a4ee28f | 158 | |
a2775c2a | 159 | --upload-pack <upload-pack>:: |
6ec311da | 160 | -u <upload-pack>:: |
d3296e37 SH |
161 | When given, and the repository to clone from is accessed |
162 | via ssh, this specifies a non-default path for the command | |
6ec311da JH |
163 | run on the other end. |
164 | ||
a57c8bac JH |
165 | --template=<template_directory>:: |
166 | Specify the directory from which templates will be used; | |
d8a8488d | 167 | (See the "TEMPLATE DIRECTORY" section of linkgit:git-init[1].) |
a57c8bac | 168 | |
84054f79 JK |
169 | --config <key>=<value>:: |
170 | -c <key>=<value>:: | |
171 | Set a configuration variable in the newly-created repository; | |
172 | this takes effect immediately after the repository is | |
173 | initialized, but before the remote history is fetched or any | |
174 | files checked out. The key is in the same format as expected by | |
175 | linkgit:git-config[1] (e.g., `core.eol=true`). If multiple | |
176 | values are given for the same key, each value will be written to | |
177 | the config file. This makes it safe, for example, to add | |
178 | additional fetch refspecs to the origin remote. | |
179 | ||
f496454e | 180 | --depth <depth>:: |
f4bf2184 | 181 | Create a 'shallow' clone with a history truncated to the |
d9d10bb8 | 182 | specified number of revisions. A shallow repository has a |
f4bf2184 JH |
183 | number of limitations (you cannot clone or fetch from |
184 | it, nor push from nor into it), but is adequate if you | |
d9d10bb8 RW |
185 | are only interested in the recent history of a large project |
186 | with a long history, and would want to send in fixes | |
f4bf2184 JH |
187 | as patches. |
188 | ||
3e6e0edd NTND |
189 | --single-branch:: |
190 | Clone only the history leading to the tip of a single branch, | |
191 | either specified by the `--branch` option or the primary | |
192 | branch remote's `HEAD` points at. When creating a shallow | |
193 | clone with the `--depth` option, this is the default, unless | |
194 | `--no-single-branch` is given to fetch the histories near the | |
195 | tips of all branches. | |
196 | ||
e7fed18a | 197 | --recursive:: |
ccdd3da6 | 198 | --recurse-submodules:: |
e7fed18a JH |
199 | After the clone is created, initialize all submodules within, |
200 | using their default settings. This is equivalent to running | |
550c66f3 | 201 | `git submodule update --init --recursive` immediately after |
e7fed18a JH |
202 | the clone is finished. This option is ignored if the cloned |
203 | repository does not have a worktree/checkout (i.e. if any of | |
204 | `--no-checkout`/`-n`, `--bare`, or `--mirror` is given) | |
205 | ||
b57fb80a NTND |
206 | --separate-git-dir=<git dir>:: |
207 | Instead of placing the cloned repository where it is supposed | |
208 | to be, place the cloned repository at the specified directory, | |
209 | then make a filesytem-agnostic git symbolic link to there. | |
210 | The result is git repository can be separated from working | |
211 | tree. | |
212 | ||
213 | ||
6ec311da | 214 | <repository>:: |
37ba0561 AR |
215 | The (possibly remote) repository to clone from. See the |
216 | <<URLS,URLS>> section below for more information on specifying | |
217 | repositories. | |
6ec311da JH |
218 | |
219 | <directory>:: | |
fb6a9f93 | 220 | The name of a new directory to clone into. The "humanish" |
0879aa28 | 221 | part of the source repository is used if no directory is |
550c66f3 BG |
222 | explicitly given (`repo` for `/path/to/repo.git` and `foo` |
223 | for `host.xz:foo/.git`). Cloning into an existing directory | |
ec00d6e0 | 224 | is only allowed if the directory is empty. |
