查看状态

$ git status

提交至仓库

$ git add 文件名

$ git commit -m "add hello world"

此时可能会弹出认证信息

*** Please tell me who you are.

Run

  git config --global user.email "you@example.com"
  git config --global user.name "Your Name"

to set your account's default identity.
Omit --global to set the identity only in this repository.

这个时候就需要输入

$ git config --global user.email "邮箱"
$ git config --global user.name "用户名"

成功后再次输入

$ git commit -m "add hello world"

[master 232df5d] add hello world
 1 file changed, 10 insertions(+)
 create mode 100644 hello_world.html

显示上面的信息表示成功提交。

这个时候可以通过

$ git log

来查看日志

进行push更新仓库

$ git push

进行认证后Github就能看到更新了。
