Shell Script YAML Parsing Guide

An example code using a YAML parser can be used to parse YAML files.

#!/bin/bash

# 安装yaml解析器
sudo apt-get install yq

# 解析yaml文件
yq r file.yaml key

In this example, the yq YAML parser is first installed, and then the yq command is used to parse the value corresponding to a specific key in the YAML file file.yaml. The value corresponding to different key-value pairs can be obtained by adjusting the value of the key as needed.
