1、创建一个新的数据库： sqlite3 文件名

先建立一个 Db 目录，并在 Db 目录中创建一个 test.db 数据库文件，打开控制台窗口，命令如下：

mkdir Db

cd Db

sqlite3 test.db

2、打开一个已经存在的数据库：sqlite3 已经存在的文件名

创建一个新数据库和打开一个已经存在的数据库命令是一模一样的，如果文件在当前目录下不存在，则新建；如果存在，则打开。

3、导入数据： .read 数据文件

打开记事本，并将下列 sql 语句复制到记事本中，保存为 test.sql 到上面说到的 Db 目录下，在命令行环境中输入

.read test.sql

即将所有的数据导入到 test.db 数据库中。
