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 | |
31b808a0 RT |
32 | current master branch, if any (this is untrue when "--single-branch" |
33 | is given; see below). | |
4607166d | 34 | |
db9819a4 | 35 | This default configuration is achieved by creating references to |
cc1b8d8b | 36 | the remote branch heads under `refs/remotes/origin` and |
db9819a4 BF |
37 | by initializing `remote.origin.url` and `remote.origin.fetch` |
38 | configuration variables. | |

41 | OPTIONS |
42 | ------- | |
a2775c2a | 43 | --local:: |
6ec311da JH |
44 | -l:: |
45 | When the repository to clone from is on a local machine, | |
2de9b711 | 46 | this flag bypasses the normal "Git aware" transport |
6ec311da JH |
47 | mechanism and clones the repository by making a copy of |
48 | HEAD and everything under objects and refs directories. | |
3d5c418f | 49 | The files under `.git/objects/` directory are hardlinked |
9197a10c JK |
50 | to save space when possible. |
51 | + | |
52 | If the repository is specified as a local path (e.g., `/path/to/repo`), | |
53 | this is the default, and --local is essentially a no-op. If the | |
54 | repository is specified as a URL, then this flag is ignored (and we | |
189260b1 JK |
55 | never use the local optimizations). Specifying `--no-local` will |
56 | override the default when `/path/to/repo` is given, using the regular | |
2de9b711 | 57 | Git transport instead. |
3d5c418f JH |
58 | |
59 | --no-hardlinks:: | |
897e3e45 ALI |
60 | Force the cloning process from a repository on a local |
61 | filesystem to copy the files under the `.git/objects` | |
62 | directory instead of using hardlinks. This may be desirable | |
63 | if you are trying to make a back-up of your repository. | |
6ec311da | 64 | |
a2775c2a EB |
65 | --shared:: |
66 | -s:: | |
67 | When the repository to clone is on the local machine, | |
4607166d | 68 | instead of using hard links, automatically setup |
550c66f3 | 69 | `.git/objects/info/alternates` to share the objects |
4607166d JH |
70 | with the source repository. The resulting repository |
71 | starts out without any object of its own. | |
84668872 MV |
72 | + |
73 | *NOTE*: this is a possibly dangerous operation; do *not* use | |
74 | it unless you understand what it does. If you clone your | |
2498a1ad | 75 | repository using this option and then delete branches (or use any |
2de9b711 | 76 | other Git command that makes any existing commit unreferenced) in the |
2498a1ad | 77 | source repository, some objects may become unreferenced (or dangling). |
2de9b711 | 78 | These objects may be removed by normal Git operations (such as `git commit`) |
483bc4f0 JN |
79 | which automatically call `git gc --auto`. (See linkgit:git-gc[1].) |
80 | If these objects are removed and were referenced by the cloned repository, | |
81 | then the cloned repository will become corrupt. | |
13354f53 JK |
82 | + |
83 | Note that running `git repack` without the `-l` option in a repository | |
84 | cloned with `-s` will copy objects from the source repository into a pack | |
85 | in the cloned repository, removing the disk space savings of `clone -s`. | |
86 | It is safe, however, to run `git gc`, which uses the `-l` option by | |
87 | default. | |
88 | + | |
89 | If you want to break the dependency of a repository cloned with `-s` on | |
90 | its source repository, you can simply run `git repack -a` to copy all | |
91 | objects from the source repository into a pack in the cloned repository. | |
a2775c2a | 92 | |
f7415b4d | 93 | --reference[-if-able] <repository>:: |
40592376 | 94 | If the reference repository is on the local machine, |
550c66f3 | 95 | automatically setup `.git/objects/info/alternates` to |
23edecbc SP |
96 | obtain objects from the reference repository. Using |
97 | an already existing repository as an alternate will | |
451e5931 | 98 | require fewer objects to be copied from the repository |
23edecbc | 99 | being cloned, reducing network and local storage costs. |
f7415b4d SB |
100 | When using the `--reference-if-able`, a non existing |
101 | directory is skipped with a warning instead of aborting | |
102 | the clone. | |
2498a1ad | 103 | + |
fb1d6dab JH |
104 | *NOTE*: see the NOTE for the `--shared` option, and also the |
105 | `--dissociate` option. | |
106 | ||
107 | --dissociate:: | |
108 | Borrow the objects from reference repositories specified | |
109 | with the `--reference` options only to reduce network | |
0181681e AR |
110 | transfer, and stop borrowing from them after a clone is made |
111 | by making necessary local copies of borrowed objects. This | |
112 | option can also be used when cloning locally from a | |
113 | repository that already borrows objects from another | |
114 | repository--the new repository will borrow objects from the | |
115 | same repository, and this option can be used to stop the | |
116 | borrowing. | |
23edecbc | 117 | |
a2775c2a | 118 | --quiet:: |
6ec311da | 119 | -q:: |
488c3163 | 120 | Operate quietly. Progress is not reported to the standard |
0d0bac67 | 121 | error stream. |
6ec311da | 122 | |
21188b1e MV |
123 | --verbose:: |
124 | -v:: | |
c54b74af TRC |
125 | Run verbosely. Does not affect the reporting of progress status |
126 | to the standard error stream. | |
5a518ad4 TRC |
127 | |
128 | --progress:: | |
488c3163 TRC |
129 | Progress status is reported on the standard error stream |
130 | by default when it is attached to a terminal, unless -q | |
131 | is specified. This flag forces progress status even if the | |
132 | standard error stream is not directed to a terminal. | |
21188b1e | 133 | |
fd0368f9 | 134 | --no-checkout:: |
a2775c2a EB |
135 | -n:: |
136 | No checkout of HEAD is performed after the clone is complete. | |
137 | ||
87e80c4b | 138 | --bare:: |
48a8c26c | 139 | Make a 'bare' Git repository. That is, instead of |
8a1a120c JH |
140 | creating `<directory>` and placing the administrative |
141 | files in `<directory>/.git`, make the `<directory>` | |
71821351 PB |
142 | itself the `$GIT_DIR`. This obviously implies the `-n` |
143 | because there is nowhere to check out the working tree. | |
144 | Also the branch heads at the remote are copied directly | |
145 | to corresponding local branch heads, without mapping | |
146 | them to `refs/remotes/origin/`. When this option is | |
36566cc0 BF |
147 | used, neither remote-tracking branches nor the related |
148 | configuration variables are created. | |
8a1a120c | 149 | |
bc699afc | 150 | --mirror:: |
6db2103f UKK |
151 | Set up a mirror of the source repository. This implies `--bare`. |
152 | Compared to `--bare`, `--mirror` not only maps local branches of the | |
153 | source to local branches of the target, it maps all refs (including | |
29b9a66f | 154 | remote-tracking branches, notes etc.) and sets up a refspec configuration such |
6db2103f UKK |
155 | that all these refs are overwritten by a `git remote update` in the |
156 | target repository. | |
bc699afc | 157 | |
ba158a32 | 158 | --origin <name>:: |
e6c310fd | 159 | -o <name>:: |
550c66f3 BG |
160 | Instead of using the remote name `origin` to keep track |
161 | of the upstream repository, use `<name>`. | |
e6c310fd | 162 | |
7a4ee28f JK |
163 | --branch <name>:: |
164 | -b <name>:: | |
165 | Instead of pointing the newly created HEAD to the branch pointed | |
550c66f3 | 166 | to by the cloned repository's HEAD, point to `<name>` branch |
31b808a0 RT |
167 | instead. In a non-bare repository, this is the branch that will |
168 | be checked out. | |
169 | `--branch` can also take tags and detaches the HEAD at that commit | |
170 | in the resulting repository. | |
7a4ee28f | 171 | |
a2775c2a | 172 | --upload-pack <upload-pack>:: |
6ec311da | 173 | -u <upload-pack>:: |
d3296e37 SH |
174 | When given, and the repository to clone from is accessed |
175 | via ssh, this specifies a non-default path for the command | |
6ec311da JH |
176 | run on the other end. |
177 | ||
a57c8bac JH |
178 | --template=<template_directory>:: |
179 | Specify the directory from which templates will be used; | |
d8a8488d | 180 | (See the "TEMPLATE DIRECTORY" section of linkgit:git-init[1].) |
a57c8bac | 181 | |
84054f79 JK |
182 | --config <key>=<value>:: |
183 | -c <key>=<value>:: | |
184 | Set a configuration variable in the newly-created repository; | |
185 | this takes effect immediately after the repository is | |
186 | initialized, but before the remote history is fetched or any | |
187 | files checked out. The key is in the same format as expected by | |
188 | linkgit:git-config[1] (e.g., `core.eol=true`). If multiple | |
189 | values are given for the same key, each value will be written to | |
190 | the config file. This makes it safe, for example, to add | |
191 | additional fetch refspecs to the origin remote. | |
192 | ||
f496454e | 193 | --depth <depth>:: |
f4bf2184 | 194 | Create a 'shallow' clone with a history truncated to the |
fc142811 | 195 | specified number of commits. Implies `--single-branch` unless |
28a1b569 | 196 | `--no-single-branch` is given to fetch the histories near the |
18a74a09 JH |
197 | tips of all branches. If you want to clone submodules shallowly, |
198 | also pass `--shallow-submodules`. | |
f4bf2184 | 199 | |
994c2aaf NTND |
200 | --shallow-since=<date>:: |
201 | Create a shallow clone with a history after the specified time. | |
202 | ||
859e5df9 NTND |
203 | --shallow-exclude=<revision>:: |
204 | Create a shallow clone with a history, excluding commits | |
205 | reachable from a specified remote branch or tag. This option | |
206 | can be specified multiple times. | |
207 | ||
0460ed2c | 208 | --[no-]single-branch:: |
3e6e0edd NTND |
209 | Clone only the history leading to the tip of a single branch, |
210 | either specified by the `--branch` option or the primary | |
28a1b569 | 211 | branch remote's `HEAD` points at. |
31b808a0 | 212 | Further fetches into the resulting repository will only update the |
a6d3bde5 | 213 | remote-tracking branch for the branch this option was used for the |
31b808a0 | 214 | initial cloning. If the HEAD at the remote did not point at any |
a6d3bde5 | 215 | branch when `--single-branch` clone was made, no remote-tracking |
31b808a0 | 216 | branch is created. |
3e6e0edd | 217 | |
0dab2468 ÆAB |
218 | --no-tags:: |
219 | Don't clone any tags, and set | |
220 | `remote.<remote>.tagOpt=--no-tags` in the config, ensuring | |
221 | that future `git pull` and `git fetch` operations won't follow | |
222 | any tags. Subsequent explicit tag fetches will still work, | |
223 | (see linkgit:git-fetch[1]). | |
224 | + | |
225 | Can be used in conjunction with `--single-branch` to clone and | |
226 | maintain a branch with no references other than a single cloned | |
227 | branch. This is useful e.g. to maintain minimal clones of the default | |
228 | branch of some repository for search indexing. | |
229 | ||
bb62e0a9 BW |
230 | --recurse-submodules[=<pathspec]:: |
231 | After the clone is created, initialize and clone submodules | |
232 | within based on the provided pathspec. If no pathspec is | |
233 | provided, all submodules are initialized and cloned. | |
234 | Submodules are initialized and cloned using their default | |
235 | settings. The resulting clone has `submodule.active` set to | |
236 | the provided pathspec, or "." (meaning all submodules) if no | |
237 | pathspec is provided. This is equivalent to running | |
550c66f3 | 238 | `git submodule update --init --recursive` immediately after |
e7fed18a JH |
239 | the clone is finished. This option is ignored if the cloned |
240 | repository does not have a worktree/checkout (i.e. if any of | |
241 | `--no-checkout`/`-n`, `--bare`, or `--mirror` is given) | |
242 | ||
d22eb044 SB |
243 | --[no-]shallow-submodules:: |
244 | All submodules which are cloned will be shallow with a depth of 1. | |
245 | ||
b57fb80a NTND |
246 | --separate-git-dir=<git dir>:: |
247 | Instead of placing the cloned repository where it is supposed | |
248 | to be, place the cloned repository at the specified directory, | |
5fe8f49b | 249 | then make a filesystem-agnostic Git symbolic link to there. |
2de9b711 | 250 | The result is Git repository can be separated from working |
b57fb80a NTND |
251 | tree. |
252 | ||
72290d6a SB |
253 | -j <n>:: |
254 | --jobs <n>:: | |
255 | The number of submodules fetched at the same time. | |
256 | Defaults to the `submodule.fetchJobs` option. | |
b57fb80a | 257 | |
6ec311da | 258 | <repository>:: |
37ba0561 AR |
259 | The (possibly remote) repository to clone from. See the |
260 | <<URLS,URLS>> section below for more information on specifying | |
261 | repositories. | |
6ec311da JH |
262 | |
263 | <directory>:: | |
fb6a9f93 | 264 | The name of a new directory to clone into. The "humanish" |
0879aa28 | 265 | part of the source repository is used if no directory is |
550c66f3 BG |
266 | explicitly given (`repo` for `/path/to/repo.git` and `foo` |
267 | for `host.xz:foo/.git`). Cloning into an existing directory | |
ec00d6e0 | 268 | is only allowed if the directory is empty. |
