1git-clone(1) 2============ 3 4NAME 5---- 6git-clone - Clone a repository into a new directory 7 8 9SYNOPSIS 10-------- 11[verse] 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 [--dissociate] [--separate-git-dir <git dir>] 16 [--depth <depth>] [--[no-]single-branch] [--no-tags] 17 [--recurse-submodules[=<pathspec>]] [--[no-]shallow-submodules] 18 [--jobs <n>] [--] <repository> [<directory>] 19 20DESCRIPTION 21----------- 22 23Clones a repository into a newly created directory, creates 24remote-tracking branches for each branch in the cloned repository 25(visible using `git branch --remotes`), and creates and checks out an 26initial branch that is forked from the cloned repository's 27currently active branch. 28 29After the clone, a plain `git fetch` without arguments will update 30all the remote-tracking branches, and a `git pull` without 31arguments will in addition merge the remote master branch into the 32current master branch, if any (this is untrue when "--single-branch" 33is given; see below). 34 35This default configuration is achieved by creating references to 36the remote branch heads under `refs/remotes/origin` and 37by initializing `remote.origin.url` and `remote.origin.fetch` 38configuration variables. 39 40 41OPTIONS 42------- 43-l:: 44--local:: 45 When the repository to clone from is on a local machine, 46 this flag bypasses the normal "Git aware" transport 47 mechanism and clones the repository by making a copy of 48 HEAD and everything under objects and refs directories. 49 The files under `.git/objects/` directory are hardlinked 50 to save space when possible. 51+ 52If the repository is specified as a local path (e.g., `/path/to/repo`), 53this is the default, and --local is essentially a no-op. If the 54repository is specified as a URL, then this flag is ignored (and we 55never use the local optimizations). Specifying `--no-local` will 56override the default when `/path/to/repo` is given, using the regular 57Git transport instead. 58 59--no-hardlinks:: 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. 64 65-s:: 66--shared:: 67 When the repository to clone is on the local machine, 68 instead of using hard links, automatically setup 69 `.git/objects/info/alternates` to share the objects 70 with the source repository. The resulting repository 71 starts out without any object of its own. 72+ 73*NOTE*: this is a possibly dangerous operation; do *not* use 74it unless you understand what it does. If you clone your 75repository using this option and then delete branches (or use any 76other Git command that makes any existing commit unreferenced) in the 77source repository, some objects may become unreferenced (or dangling). 78These objects may be removed by normal Git operations (such as `git commit`) 79which automatically call `git gc --auto`. (See linkgit:git-gc[1].) 80If these objects are removed and were referenced by the cloned repository, 81then the cloned repository will become corrupt. 82+ 83Note that running `git repack` without the `--local` option in a repository 84cloned with `--shared` will copy objects from the source repository into a pack 85in the cloned repository, removing the disk space savings of `clone --shared`. 86It is safe, however, to run `git gc`, which uses the `--local` option by 87default. 88+ 89If you want to break the dependency of a repository cloned with `--shared` on 90its source repository, you can simply run `git repack -a` to copy all 91objects from the source repository into a pack in the cloned repository. 92 93--reference[-if-able] <repository>:: 94 If the reference repository is on the local machine, 95 automatically setup `.git/objects/info/alternates` to 96 obtain objects from the reference repository. Using 97 an already existing repository as an alternate will 98 require fewer objects to be copied from the repository 99 being cloned, reducing network and local storage costs. 100 When using the `--reference-if-able`, a non existing 101 directory is skipped with a warning instead of aborting 102 the clone. 103+ 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 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. 117 118-q:: 119--quiet:: 120 Operate quietly. Progress is not reported to the standard 121 error stream. 122 123-v:: 124--verbose:: 125 Run verbosely. Does not affect the reporting of progress status 126 to the standard error stream. 127 128--progress:: 129 Progress status is reported on the standard error stream 130 by default when it is attached to a terminal, unless `--quiet` 131 is specified. This flag forces progress status even if the 132 standard error stream is not directed to a terminal. 133 134--server-option=<option>:: 135 Transmit the given string to the server when communicating using 136 protocol version 2. The given string must not contain a NUL or LF 137 character. The server's handling of server options, including 138 unknown ones, is server-specific. 139 When multiple `--server-option=<option>` are given, they are all 140 sent to the other side in the order listed on the command line. 141 142-n:: 143--no-checkout:: 144 No checkout of HEAD is performed after the clone is complete. 145 146--bare:: 147 Make a 'bare' Git repository. That is, instead of 148 creating `<directory>` and placing the administrative 149 files in `<directory>/.git`, make the `<directory>` 150 itself the `$GIT_DIR`. This obviously implies the `--no-checkout` 151 because there is nowhere to check out the working tree. 152 Also the branch heads at the remote are copied directly 153 to corresponding local branch heads, without mapping 154 them to `refs/remotes/origin/`. When this option is 155 used, neither remote-tracking branches nor the related 156 configuration variables are created. 157 158--mirror:: 159 Set up a mirror of the source repository. This implies `--bare`. 160 Compared to `--bare`, `--mirror` not only maps local branches of the 161 source to local branches of the target, it maps all refs (including 162 remote-tracking branches, notes etc.) and sets up a refspec configuration such 163 that all these refs are overwritten by a `git remote update` in the 164 target repository. 165 166-o <name>:: 167--origin <name>:: 168 Instead of using the remote name `origin` to keep track 169 of the upstream repository, use `<name>`. 170 171-b <name>:: 172--branch <name>:: 173 Instead of pointing the newly created HEAD to the branch pointed 174 to by the cloned repository's HEAD, point to `<name>` branch 175 instead. In a non-bare repository, this is the branch that will 176 be checked out. 177 `--branch` can also take tags and detaches the HEAD at that commit 178 in the resulting repository. 179 180-u <upload-pack>:: 181--upload-pack <upload-pack>:: 182 When given, and the repository to clone from is accessed 183 via ssh, this specifies a non-default path for the command 184 run on the other end. 185 186--template=<template_directory>:: 187 Specify the directory from which templates will be used; 188 (See the "TEMPLATE DIRECTORY" section of linkgit:git-init[1].) 189 190-c <key>=<value>:: 191--config <key>=<value>:: 192 Set a configuration variable in the newly-created repository; 193 this takes effect immediately after the repository is 194 initialized, but before the remote history is fetched or any 195 files checked out. The key is in the same format as expected by 196 linkgit:git-config[1] (e.g., `core.eol=true`). If multiple 197 values are given for the same key, each value will be written to 198 the config file. This makes it safe, for example, to add 199 additional fetch refspecs to the origin remote. 200+ 201Due to limitations of the current implementation, some configuration 202variables do not take effect until after the initial fetch and checkout. 203Configuration variables known to not take effect are: 204`remote.<name>.mirror` and `remote.<name>.tagOpt`. Use the 205corresponding `--mirror` and `--no-tags` options instead. 206 207--depth <depth>:: 208 Create a 'shallow' clone with a history truncated to the 209 specified number of commits. Implies `--single-branch` unless 210 `--no-single-branch` is given to fetch the histories near the 211 tips of all branches. If you want to clone submodules shallowly, 212 also pass `--shallow-submodules`. 213 214--shallow-since=<date>:: 215 Create a shallow clone with a history after the specified time. 216 217--shallow-exclude=<revision>:: 218 Create a shallow clone with a history, excluding commits 219 reachable from a specified remote branch or tag. This option 220 can be specified multiple times. 221 222--[no-]single-branch:: 223 Clone only the history leading to the tip of a single branch, 224 either specified by the `--branch` option or the primary 225 branch remote's `HEAD` points at. 226 Further fetches into the resulting repository will only update the 227 remote-tracking branch for the branch this option was used for the 228 initial cloning. If the HEAD at the remote did not point at any 229 branch when `--single-branch` clone was made, no remote-tracking 230 branch is created. 231 232--no-tags:: 233 Don't clone any tags, and set 234 `remote.<remote>.tagOpt=--no-tags` in the config, ensuring 235 that future `git pull` and `git fetch` operations won't follow 236 any tags. Subsequent explicit tag fetches will still work, 237 (see linkgit:git-fetch[1]). 238+ 239Can be used in conjunction with `--single-branch` to clone and 240maintain a branch with no references other than a single cloned 241branch. This is useful e.g. to maintain minimal clones of the default 242branch of some repository for search indexing. 243 244--recurse-submodules[=<pathspec]:: 245 After the clone is created, initialize and clone submodules 246 within based on the provided pathspec. If no pathspec is 247 provided, all submodules are initialized and cloned. 248 This option can be given multiple times for pathspecs consisting 249 of multiple entries. The resulting clone has `submodule.active` set to 250 the provided pathspec, or "." (meaning all submodules) if no 251 pathspec is provided. 252+ 253Submodules are initialized and cloned using their default settings. This is 254equivalent to running 255`git submodule update --init --recursive <pathspec>` immediately after 256the clone is finished. This option is ignored if the cloned repository does 257not have a worktree/checkout (i.e. if any of `--no-checkout`/`-n`, `--bare`, 258or `--mirror` is given) 259 260--[no-]shallow-submodules:: 261 All submodules which are cloned will be shallow with a depth of 1. 262 263--separate-git-dir=<git dir>:: 264 Instead of placing the cloned repository where it is supposed 265 to be, place the cloned repository at the specified directory, 266 then make a filesystem-agnostic Git symbolic link to there. 267 The result is Git repository can be separated from working 268 tree. 269 270-j <n>:: 271--jobs <n>:: 272 The number of submodules fetched at the same time. 273 Defaults to the `submodule.fetchJobs` option. 274 275<repository>:: 276 The (possibly remote) repository to clone from. See the 277 <<URLS,GIT URLS>> section below for more information on specifying 278 repositories. 279 280<directory>:: 281 The name of a new directory to clone into. The "humanish" 282 part of the source repository is used if no directory is 283 explicitly given (`repo` for `/path/to/repo.git` and `foo` 284 for `host.xz:foo/.git`). Cloning into an existing directory 285 is only allowed if the directory is empty. 286 287:git-clone: 1 288include::urls.txt[] 289 290EXAMPLES 291-------- 292 293* Clone from upstream: 294+ 295------------ 296$ git clone git://git.kernel.org/pub/scm/.../linux.git my-linux 297$ cd my-linux 298$ make 299------------ 300 301 302* Make a local clone that borrows from the current directory, without checking things out: 303+ 304------------ 305$ git clone -l -s -n . ../copy 306$ cd ../copy 307$ git show-branch 308------------ 309 310 311* Clone from upstream while borrowing from an existing local directory: 312+ 313------------ 314$ git clone --reference /git/linux.git \ 315 git://git.kernel.org/pub/scm/.../linux.git \ 316 my-linux 317$ cd my-linux 318------------ 319 320 321* Create a bare repository to publish your changes to the public: 322+ 323------------ 324$ git clone --bare -l /home/proj/.git /pub/scm/proj.git 325------------ 326 327 328GIT 329--- 330Part of the linkgit:git[1] suite
