USQL
USQL 是一款使用 Go 语言开发的支持 SQL/NoSQL 数据库的通用命令行工具，它支持多种主流的数据库软件，目前最新版本是usql 0.7.0。比如 PostgreSQL、MySQL、Oracle Database、SQLite3、Microsoft SQL Server 以及许多其它的数据库（包括 NoSQL 和非关系型数据库）。
USQL 的灵感来自 PostgreSQL 的 PSQL，USQL 支持大多数 PSQL 的核心特性，比如：设置变量、反引号参数。并具有 PSQL 不支持的其它功能，如语法高亮、基于上下文的自动补全和多数据库支持等。
安装 USQL
由于 USQL 使用 Go 语言开发，具备了良好的Linux、Windows等跨平台特性。USQL 安装非常简单，官方也提供二进制、Homebrew、Scoop等多种安装方式。这里我们就使用最具通用性的二进制方式安装，以 Linux 平台为例：
$ wget https://github.com/xo/usql/releases/download/v0.7.0/usql-0.7.0-linux-amd64.tar.bz2
$ tar xjvf usql-0.7.0-linux-amd64.tar.bz2
$ sudo mv usql /usr/local/bin
如果你使用其它平台，可根据实际情况在官方下载页面下载对应版本。

注：进入MySQL命令行后如果想执行Linux命令怎么办，先退出执行然后再登录MySQL？麻烦，其实可以直接用system。
