Run: clone,

GitExtension: true,

Usage: "clone [-p] [<OPTIONS>] [<USER>/]<REPOSITORY> [<DESTINATION>]",
|
|
Long: `Clone a repository from GitHub.
|
|
|
|
## Options:
|
|
-p
|
|
(Deprecated) Clone private repositories over SSH.
|
|
|
|
[<USER>/]<REPOSITORY>
|
|
<USER> defaults to your own GitHub username.
|
|
|
|
<DESTINATION>
|
|
Directory name to clone into (default: <REPOSITORY>).
|
|
|
|
## Protocol used for cloning
|
|
|
|
The 'git:' protocol will be used for cloning public repositories, while the SSH
|
|
protocol will be used for private repositories and those that you have push
|
|
access to. Alternatively, hub can be configured to use HTTPS protocol for
|
|
everything. See "HTTPS instead of git protocol" and "HUB_PROTOCOL" of hub(1).
|
|
|
|
## Examples:
|
|
$ hub clone rtomayko/ronn
|
|
> git clone git://github.com/rtomayko/ronn.git
|
|
|
|
