git克隆一个带子模块的项目【附命令】

今天爱分享给大家带来git克隆一个带子模块的项目【附命令】，希望能够帮助到大家。
这里你将克隆一个带子模块的项目。当你接收到这样一个项目，你将得到了包含子项目的目录，但里面没有文件：

$ git clone git://github.com/schacon/myproject.git
Initialized empty Git repository in /opt/myproject/.git/
remote: Counting objects: 6, done.
remote: Compressing objects: 100% (4/4), done.
remote: Total 6 (delta 0), reused 0 (delta 0)
Receiving objects: 100% (6/6), done.
$ cd myproject
$ ls -l
total 8
-rw-r--r--  1 schacon  admin   3 Apr  9 09:11 README
drwxr-xr-x  2 schacon  admin  68 Apr  9 09:11 rack
$ ls rack/
$

rack目录存在了，但是是空的。你必须运行两个命令：git submodule init来初始化你的本地配置文件，git submodule update来从那个项目拉取所有数据并检出你上层项目里所列的合适的提交：

$ git submodule init
Submodule 'rack' (git://github.com/chneukirchen/rack.git) registered for path 'rack'
$ git submodule update
