USQL
USQL 是一款使用 Go 語言開發的支持 SQL/NoSQL 數據庫的通用命令行工具，它支持多種主流的數據庫軟件，目前最新版本是usql 0.7.0。比如 PostgreSQL、MySQL、Oracle Database、SQLite3、Microsoft SQL Server 以及許多其它的數據庫（包括 NoSQL 和非關系型數據庫）。
USQL 的靈感來自 PostgreSQL 的 PSQL，USQL 支持大多數 PSQL 的核心特性，比如：設置變量、反引號參數。並具有 PSQL 不支持的其它功能，如語法高亮、基於上下文的自動補全和多數據庫支持等。
安裝 USQL
由於 USQL 使用 Go 語言開發，具備了良好的Linux、Windows等跨平台特性。USQL 安裝非常簡單，官方也提供二進制、Homebrew、Scoop等多種安裝方式。這里我們就使用最具通用性的二進制方式安裝，以 Linux 平台為例：
$ 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，可根據實際情況在官方下載頁面下載對應版本。

注：進入MySQL命令行后如果想執行Linux命令怎么辦，先退出執行然后再登錄MySQL？麻煩，其實可以直接用system。
