1: 绑定ssh keys

2：github新建仓库

echo “# SpringStack” >> README.md

git init

git add README.md

git commit -m “first commit”


git remote add origin git@github.com:xidianzxm/SpringStack.git


要关联一个远程库，使用命令git remote add origin git@server-name:path/repo-name.git；

关联后，使用命令git push -u origin master第一次推送master分支的所有内容；

此后，每次本地提交后，只要有必要，就可以使用命令git push origin master推送最新修改；

git push -u origin master


把本地库的内容推送到远程，用git push命令，实际上是把当前分支master推送到远程。

由于远程库是空的，我们第一次推送master分支时，加上了-u参数，Git不但会把本地的master分支内容推送的远程新的master分支，还会把本地的master分支和远程的master分支关联起来，在以后的推送或者拉取时就可以简化命令。

那怎么提交第二次修改呢？

你可以继续git add再git commit，也可以别着急提交第一次修改，先git add第二次修改，再git commit，就相当于把两次修改合并后一块提交了：

第一次修改 -> git add -> 第二次修改 -> git add -> git commit

现在，你又理解了Git是如何跟踪修改的，每次修改，如果不add到暂存区，那就不会加入到commit中

4:查看工作区与版本库的变化

MacBookPro:SpringStack zhangxm$ git diff HEAD -- src/main/java/com/test/helloworld/App.java
diff --git a/src/main/java/com/test/helloworld/App.java b/src/main/java/com/test/helloworld/App.java
