  12'git clone' [--template=<template_directory>]

  17DESCRIPTION
  18-----------
  19
  20Clones a repository into a newly created directory, creates
  21remote-tracking branches for each branch in the cloned repository
  22(visible using `git branch -r`), and creates and checks out an initial
  23branch equal to the cloned repository's currently active branch.
  24
  25After the clone, a plain `git fetch` without arguments will update
  26all the remote-tracking branches, and a `git pull` without
  27arguments will in addition merge the remote master branch into the
  28current master branch, if any.
  29
  30This default configuration is achieved by creating references to
  31the remote branch heads under `$GIT_DIR/refs/remotes/origin` and
  32by initializing `remote.origin.url` and `remote.origin.fetch`
  33configuration variables.

  36OPTIONS
  37-------
  38--local::
  39-l::
  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.
  52
  53--no-hardlinks::
  54        Optimize the cloning process from a repository on a
  55        local filesystem by copying files under `.git/objects`
  56        directory.
  57
  58--shared::
  59-s::
  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.
  65+
  66*NOTE*: this is a possibly dangerous operation; do *not* use
  67it unless you understand what it does. If you clone your
  68repository using this option and then delete branches (or use any
  69other git command that makes any existing commit unreferenced) in the
  70source repository, some objects may become unreferenced (or dangling).
  71These objects may be removed by normal git operations (such as 'git-commit')
  72which automatically call `git gc --auto`. (See linkgit:git-gc[1].)
  73If these objects are removed and were referenced by the cloned repository,
  74then the cloned repository will become corrupt.
  75
  76
  77
  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.
  85+
  86*NOTE*: see NOTE to --shared option.
  87
  88--quiet::
  89-q::
  90        Operate quietly.  This flag is also passed to the `rsync'
  91        command when given.
  92
  93--no-checkout::
  94-n::
  95        No checkout of HEAD is performed after the clone is complete.
  96
  97--bare::
  98        Make a 'bare' GIT repository.  That is, instead of
  99        creating `<directory>` and placing the administrative
 100        files in `<directory>/.git`, make the `<directory>`
 101        itself the `$GIT_DIR`. This obviously implies the `-n`
 102        because there is nowhere to check out the working tree.
 103        Also the branch heads at the remote are copied directly
 104        to corresponding local branch heads, without mapping
 105        them to `refs/remotes/origin/`.  When this option is
 106        used, neither remote-tracking branches nor the related
 107        configuration variables are created.
 108
 109--origin <name>::
 110-o <name>::
 111        Instead of using the remote name 'origin' to keep track
 112        of the upstream repository, use <name> instead.
 113
 114--upload-pack <upload-pack>::
 115-u <upload-pack>::
 116        When given, and the repository to clone from is accessed
 117        via ssh, this specifies a non-default path for the command
 118        run on the other end.
 119
 120--template=<template_directory>::
 121        Specify the directory from which templates will be used;
 122        if unset the templates are taken from the installation
 123        defined default, typically `/usr/share/git-core/templates`.
 124
 125--depth <depth>::
 126        Create a 'shallow' clone with a history truncated to the
 127        specified number of revisions.  A shallow repository has a
 128        number of limitations (you cannot clone or fetch from
 129        it, nor push from nor into it), but is adequate if you
 130        are only interested in the recent history of a large project
 131        with a long history, and would want to send in fixes
 132        as patches.
 133
 134<repository>::
 135        The (possibly remote) repository to clone from.  See the
 136        <<URLS,URLS>> section below for more information on specifying
 137        repositories.
 138
 139<directory>::
 140        The name of a new directory to clone into.  The "humanish"
 141        part of the source repository is used if no directory is
 142        explicitly given ("repo" for "/path/to/repo.git" and "foo"
 143        for "host.xz:foo/.git").  Cloning into an existing directory
 144        is not allowed.
