什么是分支

软件项目中启动一套单独的开发线的方法

为什么使用git

1.可以很好的避免版本兼容开发的问题，避免不同版本之间的相互影响。
2.封装一个开发阶段。
3.解决bug的时候新建分支，用于对该bug的研究。

git中跟分支相关的命令

git branch 分支名---创建一个新的分支
git branch ---不加任何参数，列出所有的分支，分支前面有*号，代表该分支为当前所在分支
* 创建分支的时候，分支名不能使用特殊符号
git branch -d 分支名---删除分支
git branch -m 旧分支名 新分支名---分支名改名
git checkout 分支名---切换分支，如果在分支上面对文件进行修改之后，没有commit就切换到另外一个支支
这个时候会报错，因为没有commit的文件在切换分支之后会不覆盖
git checkout -f 分支名---强制切换分支。

* master
kangdeMacBook-Air:cedarhd kang$ git branch v1.0   #新建一个v1.0的分支
kangdeMacBook-Air:cedarhd kang$ git branch

Switched to branch ‘v1.0‘
