我们这里下载的是命令行版本，所以是一个可执行文件，还有一个动态链接库版本，如果你的应用程序需要嵌入式数据库，可以下载这个版本。当然，如果你愿意折腾，下载源代码自己编译也是可以的。下载完成，解压出来就一个文件： sqlite3.exe ，可以放置到任意一个路径下，然后把这个路径加入到 PATH 环境变量中，这样我们就可以随时在控制台中运行 SQLite 命令行工具了。

有好几种显示模式，默认的是 list 显示模式，一般我们使用 column 显示模式，还有其他几种显示模式可以 .help 看 mode 相关内容。看看下面的图，和上面是不是显示的不一样了？
如果我们每次进入命令行都要重新设置显示格式，很麻烦，其实 .show 命令列出的所有设置项都可以保存到一个 .sqliterc 文件中，这样每次进入命令行就自动设置好了。.sqlterc 文件在 Linux 下保存在用户的 Home 目录下，在 Windows 下可以保存到任何目录下，但是需要设置环境变量让数据库引擎能找到它，感兴趣的可以看看帮助。
