NAME |

|
git-clone - Clone a repository into a new directory |
|
|
|
|
|
SYNOPSIS |
|
-------- |
|
[verse] |
|
'git clone' [--template=<template_directory>] |
|
[-l] [-s] [--no-hardlinks] [-q] [-n] [--bare] [--mirror] |
|
[-o <name>] [-u <upload-pack>] [--reference <repository>] |
|
[--depth <depth>] [--] <repository> [<directory>] |
|
|
|
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 equal to 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 default configuration is achieved by creating references to |
|
the remote branch heads under `$GIT_DIR/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 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. This is now the default when |
|
the source repository is specified with `/path/to/repo` |
|
syntax, so it essentially is a no-op option. To force |
|
copying instead of hardlinking (which may be desirable |
|
if you are trying to make a back-up of your repository), |
|
but still avoid the usual "git aware" transport |
|
mechanism, `--no-hardlinks` can be used. |
|
|
|
--no-hardlinks:: |
|
Optimize the cloning process from a repository on a |
|
local filesystem by copying files under `.git/objects` |
|
directory. |
|
|
|
--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. |
|
|
|
|
|
|
|
--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 fewer objects to be copied from the repository |
|
being cloned, reducing network and local storage costs. |
|
+ |
|
*NOTE*: see NOTE to --shared option. |
|
|
|
--quiet:: |
|
-q:: |
|
Operate quietly. This flag is also passed to the `rsync' |
|
command when given. |
|
|
|
--verbose:: |
|
-v:: |
|
Display the progressbar, even in case the standard output is not |
|
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 remote repository. This implies --bare. |
|
|
|
--origin <name>:: |
|
-o <name>:: |
|
Instead of using the remote name 'origin' to keep track |
|
of the upstream repository, use <name>. |
|
|
|
--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; |
|
if unset the templates are taken from the installation |
|
defined default, typically `/usr/share/git-core/templates`. |
|
|
|
--depth <depth>:: |
|
Create a 'shallow' clone with a history truncated to the |
|
specified number of revisions. A shallow repository has a |
|
number of limitations (you cannot clone or fetch from |
|
it, nor push from nor into it), but is adequate if you |
|
are only interested in the recent history of a large project |
|
with a long history, and would want to send in fixes |
|
as patches. |
|
|
|
<repository>:: |
|
The (possibly remote) repository to clone from. See the |
|
<<URLS,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 not allowed. |
