往github提交代码流程

一 首先在Github新建一个仓库，回到首页，点击右上角的New repository新建仓库。

 

二  在本地依次使用下面命令

…or create a new repository on the command line

 

echo "# opus" >> README.md
git init
git add README.md
git commit -m "first commit"
git remote add origin https://github.com/DyLanCao/opus.git
git push -u origin master

…or push an existing repository from the command line

 

git remote add origin https://github.com/DyLanCao/opus.git
git push -u origin master

三 问题
1 输入：

git remote add origin https://github.com/DyLanCao/opus.git
上报错误：fatal: remote origin already exists.

解决方法：
首先：git remote rm origin 
然后再使用命令：git remote add origin https://github.com/DyLanCao/opus.git
