在github上传和更新文件

主要过程详解如下：

对于更新主要流程是：

1. 关联远程

$ git remote add origin git@github.com:susanhc/programming.git

• susanhc是账号名称
• programming是你所建的仓库
  上述语句将二者进行关联

这可以解决错误：

fatal: 'origin' does not appear to be a git repository
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

但是有可能在关联远程或push出现如下错误：

fatal: Not a git repository (or any of the parent directories): .git 

解决：在命令行输入 git init 然后回车就好了

2. 长传本地文件

$ git add .

• 跟踪任何的文件改动

$ git commit -m "34"

添加注释，引号中是你的解释内容

$ git push origin master

把本地文件上传到github仓库中去

• git push 时报错 error：failed to push some refs to ‘git@xxxxxx’

原因：这是一个新建的一个仓库，提交到github时，没有 pull下来，导致 github中的README.md文件不在本地代码目录中

$ git push -u  origin master
To github.com:Houttuyniae/notes.git
 ! [rejected]        master -> master (non-fast-forward)
error: failed to push some refs to 'git@github.com:Houttuyniae/notes.git'
hint: Updates were rejected because the tip of your current branch is behind
hint: its remote counterpart. Integrate the remote changes (e.g.
hint: 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.

需要先执行 git pull --rebase origin master 把 README.md 下来

如果在你pull之前，又执行了commit，提交了一次，则会报错

$ git pull --rebase origin master
error: cannot pull with rebase: You have unstaged changes.
error: additionally, your index contains uncommitted changes.
error: please commit or stash them.

需要先执行 git stash 缓存一下 最后在 push

$ git push -u  origin master
