GIT命令自学（主要给自己看）

首先从GIT官网（https://git-scm.com/）下载程序安装。

推荐一个GIT教程网站：https://www.liaoxuefeng.com/wiki/0013739516305929606dd18361248578c67b8067c8c017b000

查看版本：

$ git --version
git version 2.15.1.windows.2

克隆：

$ git clone [email protected]:***********/mmall.git

下面是码云（https://gitee.com/）添加公钥的方法：

Administrator@PC-201701211024 MINGW64 ~/Desktop
$ ssh-keygen -t rsa -C "*********@qq.com"
Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/Administrator/.ssh/id_rsa):
/c/Users/Administrator/.ssh/id_rsa already exists.
Overwrite (y/n)?

Administrator@PC-201701211024 MINGW64 ~/Desktop
$ cat ~/.ssh/id_rsa.pub
