git之简单入门及操作～
看了bili的教程，https://www.bilibili.com/video/av23853294?from=search&seid=3300012850779227291
特此整理下。
1、首先安装git，然后最好国内镜像，否则下载很慢
2、其次，可以注册github的账号，后面会用到。
3、把git和github链接起来，就是建立连接，右键打开git bash here，输入ssh-keygen，会中C:UsersAdministrator.ssh文件夹下生成两个文件，打开id_rsa.pub，把里面的信息全部拷贝的github之SSH and GPG keys中。这样就把git和github建立了链接。
4、新建一个文件，打开文件，右键git bash here，
可以看到如下信息：
a、git init命令 Administrator@PC-20150323YSLL MINGW64 ~/Desktop/maple_stm_git $ git init Initialized empty Git repository in C:/Users/Administrator/Desktop/maple_stm_git/.git/ b、git remote add origin命令，把github的链接和本地文件建立连接 Administrator@PC-20150323YSLL MINGW64 ~/Desktop/maple_stm_git (master) $ git remote add origin https://github.com/liming2013/maple.git c、git pull origin master命令，下载代码到本地文件夹中 Administrator@PC-20150323YSLL MINGW64 ~/Desktop/maple_stm_git (master) $ git pull origin master remote: Enumerating objects: 233, done. remote: Total 233 (delta 0), reused 0 (delta 0), pack-reused 233 Receiving objects: 100% (233/233), 7.86 MiB | 74.00 KiB/s, done.
