使用 Trino
前面我们学习了如何安装、配置和启动
Trino
，现在学习如何使用它。
3.1 Trino CLI
Trino CLI
提供了一个基于终端的交互式
shell
。你可以通过它运行查询并与
Trino
服务端
交互来检查其元数据。
3.1.1
使用入门
正如
Trino
服务端一样，
Trino CLI
的二进制发布版本可以在
Maven Central Repository
中找到。这个
CLI
应用程序以可执行
JAR
包的形式提供，你可以像使用普通
UNIX
可执
行程序一样使用它。
你可以从如下链接查看可用版本的列表：
https://repo.maven.apache.org/maven2/io/trino/trino-cli
找到与你使用的
Trino
服务端版本相一致的
CLI
版本，从版本目录中下载对应的
*-execu-
table.jar
文件，然后将其重命名为
trino
。下列命令展示了如何使用
wget
完成上述步骤
并安装
392
版本：
$ wget -O trino \
https://repo.maven.apache.org/maven2/\
io/trino/trino-cli/392/trino-cli-392-executable.jar
你需要确保文件具有可执行权限。为了方便使用，将其放置在
PATH
中。例如，你可以
将其复制到
~/bin
，并将此目录添加到
PATH
中：
$ chmod +x trino
$ mv trino ~/bin
$ export PATH=~/bin/:$PATH
