Git基础入门

一、创建版本库

//创建文件夹
$ mkdir intco
//到当前目录
$ cd intco
//显示当前目录
$ pwd
/intco/project
//将此目录变成Git可以管理的仓库
$ git init
Initialized empty Git repository in D:/Code/Git/intco/project/.git/

在intco文件夹下创建readme.txt文件，内容为：

Git is a version control system.
Git is free software.

//使用git add,把文件添加到仓库
$ git add readme.txt
//使用git commit把文件提交给仓库，
$ git commit -m "Add two rows"
[master 7e5b09e] Add two rows
 1 file changed, 2 insertions(+), 1 deletions(-)

 Git添加文件需要add、commit两步操作，由于commit可以一次提交很多文件，所以可以多次add不同的文件。

$ git add file1.txt
$ git add file2.txt file3.txt
$ git commit -m "add 3 files."

二、操作流程

//查看当前仓库的状态
$ git status
//查看具体修改的内容
$ git diff readme.txt
diff --git a/readme.txt b/readme.txt
index d8976ef..013b5bc 100644
