How to use git hub

1. 安装完成后，还需要最后一步设置，在命令行输入：

$ git config --global user.name "Allen Zhong"
$ git config --global user.email "zhongyu211@126.com"

 

2. git init

Initialized empty Git repository in /Users/michael/learngit/.git/

一定要放到learngit目录下（子目录也行），因为这是一个Git仓库，放到其他地方Git再厉害也找不到这个文件。

 

和把大象放到冰箱需要3步相比，把一个文件放到Git仓库只需要两步。

 

3. 用命令git add告诉Git，把文件添加到仓库：

 

$ git add readme.txt

执行上面的命令，没有任何显示，这就对了，Unix的哲学是“没有消息就是好消息”，说明添加成功。

 

4. 用命令git commit告诉Git，把文件提交到仓库：

 　　#This command is very useful for it can totally replace the git bub repository

$ git commit -m -a "wrote a readme file"

[master (root-commit) cb926e7] wrote a readme file

 1 file changed, 2 insertions(+)

 create mode 100644 readme.txt

运行git status命令看看结果：

 

5. 使用 git status 查看结果

$ git status

# On branch master

# Changes not staged for commit:

#   (use "git add <file>..." to update what will be committed)

#   (use "git checkout -- <file>..." to discard changes in working directory)

#

#    modified:   readme.txt

#

no changes added to commit (use "git add" and/or "git commit -a")

6. 使用 git diff 查看文件变化

$ git diff readme.txt

diff --git a/readme.txt b/readme.txt

index 46d49bf..9247db6 100644

--- a/readme.txt
