使用 Michael Hartl 的 Ruby on Rails 说明，我在命令行中输入了以下内容：
$ git init
$ git add .
$ git status
我得到的输出没有意义。看起来我计算机上的所有内容都已提交，即我的网络浏览历史记录。

在尝试提交之前，我$ rails server在另一个终端中运行并得到以下输出：
=> Booting WEBrick
=> Rails 3.2.8 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server

从上一个问题，我知道$ rails server将继续运行，直到我关闭终端窗口。请帮忙！为什么我的计算机中的所有内容，包括网络历史记录都提交给 Git？
