  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 -r`), 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.

  41OPTIONS
  42-------
  43--local::
  44-l::
  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--shared::
  66-s::
  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 `-l` option in a repository
  84cloned with `-s` will copy objects from the source repository into a pack
  85in the cloned repository, removing the disk space savings of `clone -s`.
  86It is safe, however, to run `git gc`, which uses the `-l` option by
  87default.
  88+
  89If you want to break the dependency of a repository cloned with `-s` 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 <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+
 101*NOTE*: see the NOTE for the `--shared` option, and also the
 102`--dissociate` option.
 103
 104--dissociate::
 105        Borrow the objects from reference repositories specified
 106        with the `--reference` options only to reduce network
 107        transfer, and stop borrowing from them after a clone is made
 108        by making necessary local copies of borrowed objects.  This
 109        option can also be used when cloning locally from a
 110        repository that already borrows objects from another
 111        repository--the new repository will borrow objects from the
 112        same repository, and this option can be used to stop the
 113        borrowing.
 114
 115--quiet::
 116-q::
 117        Operate quietly.  Progress is not reported to the standard
 118        error stream. This flag is also passed to the `rsync'
 119        command when given.
 120
 121--verbose::
 122-v::
 123        Run verbosely. Does not affect the reporting of progress status
 124        to the standard error stream.
 125
 126--progress::
 127        Progress status is reported on the standard error stream
 128        by default when it is attached to a terminal, unless -q
 129        is specified. This flag forces progress status even if the
 130        standard error stream is not directed to a terminal.
 131
 132--no-checkout::
 133-n::
 134        No checkout of HEAD is performed after the clone is complete.
 135
 136--bare::
 137        Make a 'bare' Git repository.  That is, instead of
 138        creating `<directory>` and placing the administrative
 139        files in `<directory>/.git`, make the `<directory>`
 140        itself the `$GIT_DIR`. This obviously implies the `-n`
 141        because there is nowhere to check out the working tree.
 142        Also the branch heads at the remote are copied directly
 143        to corresponding local branch heads, without mapping
 144        them to `refs/remotes/origin/`.  When this option is
 145        used, neither remote-tracking branches nor the related
 146        configuration variables are created.
 147
 148--mirror::
 149        Set up a mirror of the source repository.  This implies `--bare`.
 150        Compared to `--bare`, `--mirror` not only maps local branches of the
 151        source to local branches of the target, it maps all refs (including
 152        remote-tracking branches, notes etc.) and sets up a refspec configuration such
 153        that all these refs are overwritten by a `git remote update` in the
 154        target repository.
 155
 156--origin <name>::
 157-o <name>::
 158        Instead of using the remote name `origin` to keep track
 159        of the upstream repository, use `<name>`.
 160
 161--branch <name>::
 162-b <name>::
 163        Instead of pointing the newly created HEAD to the branch pointed
 164        to by the cloned repository's HEAD, point to `<name>` branch
 165        instead. In a non-bare repository, this is the branch that will
 166        be checked out.
 167        `--branch` can also take tags and detaches the HEAD at that commit
 168        in the resulting repository.
 169
 170--upload-pack <upload-pack>::
 171-u <upload-pack>::
 172        When given, and the repository to clone from is accessed
 173        via ssh, this specifies a non-default path for the command
 174        run on the other end.
 175
 176--template=<template_directory>::
 177        Specify the directory from which templates will be used;
 178        (See the "TEMPLATE DIRECTORY" section of linkgit:git-init[1].)
 179
 180--config <key>=<value>::
 181-c <key>=<value>::
 182        Set a configuration variable in the newly-created repository;
 183        this takes effect immediately after the repository is
 184        initialized, but before the remote history is fetched or any
 185        files checked out.  The key is in the same format as expected by
 186        linkgit:git-config[1] (e.g., `core.eol=true`). If multiple
 187        values are given for the same key, each value will be written to
 188        the config file. This makes it safe, for example, to add
 189        additional fetch refspecs to the origin remote.
 190
 191--depth <depth>::
 192        Create a 'shallow' clone with a history truncated to the
 193        specified number of revisions. Implies `--single-branch` unless
 194        `--no-single-branch` is given to fetch the histories near the
 195        tips of all branches. This implies `--shallow-submodules`. If
 196        you want to have a shallow superproject clone, but full submodules,
 197        also pass `--no-shallow-submodules`.
 198
 199--[no-]single-branch::
 200        Clone only the history leading to the tip of a single branch,
 201        either specified by the `--branch` option or the primary
 202        branch remote's `HEAD` points at. When creating a shallow
 203        clone with the `--depth` option, this is the default, unless
 204        `--no-single-branch` is given to fetch the histories near the
 205        tips of all branches.
 206        Further fetches into the resulting repository will only update the
 207        remote-tracking branch for the branch this option was used for the
 208        initial cloning.  If the HEAD at the remote did not point at any
 209        branch when `--single-branch` clone was made, no remote-tracking
 210        branch is created.
 211
 212--recursive::
 213--recurse-submodules::
 214        After the clone is created, initialize all submodules within,
 215        using their default settings. This is equivalent to running
 216        `git submodule update --init --recursive` immediately after
 217        the clone is finished. This option is ignored if the cloned
 218        repository does not have a worktree/checkout (i.e. if any of
 219        `--no-checkout`/`-n`, `--bare`, or `--mirror` is given)
 220
 221--[no-]shallow-submodules::
 222        All submodules which are cloned will be shallow with a depth of 1.
 223
 224--separate-git-dir=<git dir>::
 225        Instead of placing the cloned repository where it is supposed
 226        to be, place the cloned repository at the specified directory,
 227        then make a filesystem-agnostic Git symbolic link to there.
 228        The result is Git repository can be separated from working
 229        tree.
 230
 231-j <n>::
 232--jobs <n>::
 233        The number of submodules fetched at the same time.
 234        Defaults to the `submodule.fetchJobs` option.
 235
 236<repository>::
 237        The (possibly remote) repository to clone from.  See the
 238        <<URLS,URLS>> section below for more information on specifying
 239        repositories.
 240
 241<directory>::
 242        The name of a new directory to clone into.  The "humanish"
 243        part of the source repository is used if no directory is
 244        explicitly given (`repo` for `/path/to/repo.git` and `foo`
 245        for `host.xz:foo/.git`).  Cloning into an existing directory
 246        is only allowed if the directory is empty.
