git-tips

git小贴士：git常用命令集合（git的'奇技淫巧'？😱）

所有人看过来

1. Fork于tips项目

2. 一定要先测试命令的效果后，再用于工作环境中，以防造成不能弥补的后果！

3. 所有的命令都在git version 2.7.4 (Apple Git-66)下测试通过（安全可食用😊）

统一概念

1. 工作区：改动（增删文件和文本）
2. 暂存区：输入命令：git add 改动的文件名，此次改动就放到了‘暂存区’
3. 本地仓库：输入命令：git commit 此次修改的描述，此次改动就放到了’本地仓库’，每个commit，我叫它为一个‘版本’
4. 远程仓库：输入命令：git push 远程仓库，此次改动就放到了‘远程仓库’（github等)

Everyday Git in twenty commands or so
