The new --reference flag introduced to git-clone in GIT 1.3.0 was not documented but is rather handy. So document it. Also corrected a minor issue with the documentation for the -s flag; the info/alternates file name was spelled wrong. Signed-off-by: Shawn O.

NAME

|
----
|
|
git-clone - Clones a repository
|
|
|
|
|
|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'git-clone' [-l [-s]] [-q] [-n] [--bare] [-o <name>] [-u <upload-pack>]
|
|
[--reference <repository>]
|
|
<repository> [<directory>]
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
Clones a repository into a newly created directory. All remote
|
|
branch heads are copied under `$GIT_DIR/refs/heads/`, except
|
|
that the remote `master` is also copied to `origin` branch.
|
|
|
|
In addition, `$GIT_DIR/remotes/origin` file is set up to have
|
|
this line:
|
|
|
|
Pull: master:origin
|
|
|
|
This is to help the typical workflow of working off of the
|
|
remote `master` branch. Every time `git pull` without argument
|
|
is run, the progress on the remote `master` branch is tracked by
|
|
copying it into the local `origin` branch, and merged into the
|
|
branch you are currently working on. Remote branches other than
|
|
`master` are also added there to be tracked.
|
|
|
|
|
|
OPTIONS
|
|
-------
|
|
--local::
|
|
-l::
|
|
When the repository to clone from is on a local machine,
|
|
this flag bypasses 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.
|
|
|
|
--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.
|
|
|
|
--reference <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 less objects to be copied from the repository
|
|
being cloned, reducing network and local storage costs.
|
|
|
|
--quiet::
|
|
-q::
|
|
Operate quietly. This flag is passed to "rsync" and
|
|
"git-clone-pack" commands when given.
|
|
|
|
-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 implies `-n` option. When
|
|
this option is used, neither the `origin` branch nor the
|
|
default `remotes/origin` file is created.
|
|
|
|
-o <name>::
|
|
Instead of using the branch name 'origin' to keep track
|
|
of the upstream repository, use <name> instead. Note
|
|
that the shorthand name stored in `remotes/origin` is
|
|
not affected, but the local branch name to pull the
|
|
remote `master` branch into is.
|
|
|
|
--upload-pack <upload-pack>::
|
|
-u <upload-pack>::
|
|
When given, and the repository to clone from is handled
|
|
by 'git-clone-pack', '--exec=<upload-pack>' is passed to
|
|
the command to specify non-default path for the command
|
|
run on the other end.
|
|
|
|
<repository>::
|
|
The (possibly remote) repository to clone from. It can
|
|
be any URL git-fetch supports.
|
|
|
|
<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 not allowed.

Examples
|
|
~~~~~~~~
|
|
|
|
Clone from upstream::
|
|
+
|
|
------------
|
|
$ git clone git://git.kernel.org/pub/scm/.../linux-2.6 my2.6
|
|
$ cd my2.6
|
|
$ make
|
|
------------
|
|
|
|
|
|
Make a local clone that borrows from the current directory, without checking things out::
|
|
+
|
|
------------
|
|
$ git clone -l -s -n . ../copy
|
|
$ cd copy
|
|
$ git show-branch
|
|
------------
|
|
|
|
|
|
Clone from upstream while borrowing from an existing local directory::
|
|
+
|
|
------------
|
|
$ git clone --reference my2.6 \
|
|
git://git.kernel.org/pub/scm/.../linux-2.7 \
|
|
my2.7
|
|
$ cd my2.7
|
|
------------
|
|
|
|
|
|
Create a bare repository to publish your changes to the public::
|
|
+
|
|
------------
|
|
$ git clone --bare -l /home/proj/.git /pub/scm/proj.git
|
|
------------
|
|
|
|
|
|
Create a repository on the kernel.org machine that borrows from Linus::
|
|
+
|
|
------------
|
|
$ git clone --bare -l -s /pub/scm/.../torvalds/linux-2.6.git \
|
|
/pub/scm/.../me/subsys-2.6.git
