DESCRIPTION
-----------

Clones a repository into a newly created directory, creates
remote-tracking branches for each branch in the cloned repository
(visible using `git branch -r`), and creates and checks out an
initial branch that is forked from the cloned repository's
currently active branch.

After the clone, a plain `git fetch` without arguments will update
all the remote-tracking branches, and a `git pull` without
arguments will in addition merge the remote master branch into the
current master branch, if any (this is untrue when "--single-branch"
is given; see below).

This default configuration is achieved by creating references to
the remote branch heads under `refs/remotes/origin` and
by initializing `remote.origin.url` and `remote.origin.fetch`
configuration variables.


OPTIONS
-------
--local::
-l::
        When the repository to clone from is on a local machine,
        this flag bypasses the normal "Git aware" transport
        mechanism and clones the repository by making a copy of
        HEAD and everything under objects and refs directories.
        The files under `.git/objects/` directory are hardlinked
        to save space when possible.
+
If the repository is specified as a local path (e.g., `/path/to/repo`),
this is the default, and --local is essentially a no-op.  If the
repository is specified as a URL, then this flag is ignored (and we
never use the local optimizations).  Specifying `--no-local` will
override the default when `/path/to/repo` is given, using the regular
Git transport instead.

--no-hardlinks::
        Force the cloning process from a repository on a local
        filesystem to copy the files under the `.git/objects`
        directory instead of using hardlinks. This may be desirable
        if you are trying to make a back-up of your repository.

--shared::
-s::
        When the repository to clone is on the local machine,
        instead of using hard links, automatically setup
        `.git/objects/info/alternates` to share the objects
        with the source repository.  The resulting repository
        starts out without any object of its own.
+
*NOTE*: this is a possibly dangerous operation; do *not* use
it unless you understand what it does. If you clone your
repository using this option and then delete branches (or use any
other Git command that makes any existing commit unreferenced) in the
source repository, some objects may become unreferenced (or dangling).
These objects may be removed by normal Git operations (such as `git commit`)
which automatically call `git gc --auto`. (See linkgit:git-gc[1].)
If these objects are removed and were referenced by the cloned repository,
then the cloned repository will become corrupt.
+
Note that running `git repack` without the `-l` option in a repository
cloned with `-s` will copy objects from the source repository into a pack
in the cloned repository, removing the disk space savings of `clone -s`.
It is safe, however, to run `git gc`, which uses the `-l` option by
default.
+
If you want to break the dependency of a repository cloned with `-s` on
its source repository, you can simply run `git repack -a` to copy all
objects from the source repository into a pack in the cloned repository.

--reference[-if-able] <repository>::
        If the reference repository is on the local machine,
        automatically setup `.git/objects/info/alternates` to
        obtain objects from the reference repository.  Using
        an already existing repository as an alternate will
        require fewer objects to be copied from the repository
        being cloned, reducing network and local storage costs.
        When using the `--reference-if-able`, a non existing
        directory is skipped with a warning instead of aborting
        the clone.
+
*NOTE*: see the NOTE for the `--shared` option, and also the
`--dissociate` option.

--dissociate::
        Borrow the objects from reference repositories specified
        with the `--reference` options only to reduce network
        transfer, and stop borrowing from them after a clone is made
        by making necessary local copies of borrowed objects.  This
        option can also be used when cloning locally from a
        repository that already borrows objects from another
        repository--the new repository will borrow objects from the
        same repository, and this option can be used to stop the
        borrowing.

--quiet::
-q::
        Operate quietly.  Progress is not reported to the standard
        error stream.

--verbose::
-v::
        Run verbosely. Does not affect the reporting of progress status
        to the standard error stream.

--progress::
        Progress status is reported on the standard error stream
        by default when it is attached to a terminal, unless -q
        is specified. This flag forces progress status even if the
        standard error stream is not directed to a terminal.

--no-checkout::
-n::
        No checkout of HEAD is performed after the clone is complete.

--bare::
        Make a 'bare' Git repository.  That is, instead of
        creating `<directory>` and placing the administrative
        files in `<directory>/.git`, make the `<directory>`
        itself the `$GIT_DIR`. This obviously implies the `-n`
        because there is nowhere to check out the working tree.
        Also the branch heads at the remote are copied directly
        to corresponding local branch heads, without mapping
        them to `refs/remotes/origin/`.  When this option is
        used, neither remote-tracking branches nor the related
        configuration variables are created.

--mirror::
        Set up a mirror of the source repository.  This implies `--bare`.
        Compared to `--bare`, `--mirror` not only maps local branches of the
        source to local branches of the target, it maps all refs (including
        remote-tracking branches, notes etc.) and sets up a refspec configuration such
        that all these refs are overwritten by a `git remote update` in the
        target repository.

--origin <name>::
-o <name>::
        Instead of using the remote name `origin` to keep track
        of the upstream repository, use `<name>`.

--branch <name>::
-b <name>::
        Instead of pointing the newly created HEAD to the branch pointed
        to by the cloned repository's HEAD, point to `<name>` branch
        instead. In a non-bare repository, this is the branch that will
        be checked out.
        `--branch` can also take tags and detaches the HEAD at that commit
        in the resulting repository.

--upload-pack <upload-pack>::
-u <upload-pack>::
        When given, and the repository to clone from is accessed
        via ssh, this specifies a non-default path for the command
        run on the other end.

--template=<template_directory>::
        Specify the directory from which templates will be used;
        (See the "TEMPLATE DIRECTORY" section of linkgit:git-init[1].)

--config <key>=<value>::
-c <key>=<value>::
        Set a configuration variable in the newly-created repository;
        this takes effect immediately after the repository is
        initialized, but before the remote history is fetched or any
        files checked out.  The key is in the same format as expected by
        linkgit:git-config[1] (e.g., `core.eol=true`). If multiple
        values are given for the same key, each value will be written to
        the config file. This makes it safe, for example, to add
        additional fetch refspecs to the origin remote.
+
Due to limitations of the current implementation, some configuration
variables do not take effect until after the initial fetch and checkout.
Configuration variables known to not take effect are:
`remote.<name>.mirror` and `remote.<name>.tagOpt`.  Use the
corresponding `--mirror` and `--no-tags` options instead.

--depth <depth>::
        Create a 'shallow' clone with a history truncated to the
        specified number of commits. Implies `--single-branch` unless
        `--no-single-branch` is given to fetch the histories near the
        tips of all branches. If you want to clone submodules shallowly,
        also pass `--shallow-submodules`.

--shallow-since=<date>::
        Create a shallow clone with a history after the specified time.

--shallow-exclude=<revision>::
        Create a shallow clone with a history, excluding commits
        reachable from a specified remote branch or tag.  This option
        can be specified multiple times.

--[no-]single-branch::
        Clone only the history leading to the tip of a single branch,
        either specified by the `--branch` option or the primary
        branch remote's `HEAD` points at.
        Further fetches into the resulting repository will only update the
        remote-tracking branch for the branch this option was used for the
        initial cloning.  If the HEAD at the remote did not point at any
        branch when `--single-branch` clone was made, no remote-tracking
        branch is created.

--no-tags::
        Don't clone any tags, and set
        `remote.<remote>.tagOpt=--no-tags` in the config, ensuring
        that future `git pull` and `git fetch` operations won't follow
        any tags. Subsequent explicit tag fetches will still work,
        (see linkgit:git-fetch[1]).
+
Can be used in conjunction with `--single-branch` to clone and
maintain a branch with no references other than a single cloned
branch. This is useful e.g. to maintain minimal clones of the default
branch of some repository for search indexing.

--recurse-submodules[=<pathspec]::
        After the clone is created, initialize and clone submodules
        within based on the provided pathspec.  If no pathspec is
        provided, all submodules are initialized and cloned.
        This option can be given multiple times for pathspecs consisting
        of multiple entries.  The resulting clone has `submodule.active` set to
        the provided pathspec, or "." (meaning all submodules) if no
        pathspec is provided.
+
Submodules are initialized and cloned using their default settings. This is
equivalent to running
`git submodule update --init --recursive <pathspec>` immediately after
the clone is finished. This option is ignored if the cloned repository does
not have a worktree/checkout (i.e. if any of `--no-checkout`/`-n`, `--bare`,
or `--mirror` is given)

--[no-]shallow-submodules::
        All submodules which are cloned will be shallow with a depth of 1.

--separate-git-dir=<git dir>::
        Instead of placing the cloned repository where it is supposed
        to be, place the cloned repository at the specified directory,
        then make a filesystem-agnostic Git symbolic link to there.
        The result is Git repository can be separated from working
        tree.

-j <n>::
--jobs <n>::
        The number of submodules fetched at the same time.
        Defaults to the `submodule.fetchJobs` option.

<repository>::
        The (possibly remote) repository to clone from.  See the
        <<URLS,GIT URLS>> section below for more information on specifying
        repositories.

<directory>::
        The name of a new directory to clone into.  The "humanish"
        part of the source repository is used if no directory is
        explicitly given (`repo` for `/path/to/repo.git` and `foo`
        for `host.xz:foo/.git`).  Cloning into an existing directory
        is only allowed if the directory is empty.
