git命令可以分为短和长选项。例如：
git commit -m "hello git"
git commit --message="hello git"
以上两条命令式等价的
1.Git入门
有两种简历git版本库的技术。可以从头开始创建，用现有的内容填充它，或者可以clone一个已有的版本库，从一个空的版本库比较简单，所有从空的版本库开始吧。
1.1 创建一个初始版本库
1 mkdir ~\public 2 cd ~\public 3 echo 'hello git' > index.html 4 git init
git init将public目录转化为了git版本库。
git不关心你是从一个空白的目录还是一个装满目录的文件开始的。在这两种情况下将目录转换为GIT版本库是完全一样的。
为了显示目录是一个git版本库。git init创建了一个隐藏的.git目录。git将所有修订信息都放在这唯一的顶层.git目录中。
1.2 将文件添加进版本库
1 git add index.html 2 git commit -m 'init' 3 git status
如果目录中有很多文件，可以用git add . 来添加进版本库。
git将add、remove和commit分开，以避免频繁的变化。
add仅仅只是把改变暂存在了本地。commit才是上传了改变。
在add后，如果运行git status 可以查看git下一次将会把index.html上传给版本库
除了原数据以外，git每次提交的时候，还会包括一些元数据，类似日志信息和作出本次变更的作者。
如果仅仅只是运行git commit ，系统会调用设定好的编辑器来让你编辑
