Beginners Course: Jq Command Tutorials to Parse JSON Data | Udemy

This course is for anyone who works with JSON on Unix/Linux Command-line or using Bash Shell Scripts.

Currently, DevOps Automation is more into REST APIs usage and REST APIs Response is JSON. So, to implement bash shell scripts by using REST APIs then you must know how to parse the response of REST API (I.e, parsing JSON Data).

JQ is a command-line utility developed to Parse JSON data. Parsing JSON Data is nothing but – Reading, Writing and Modifying the JSON Data.

We can also parse JSON Data with sed, awk, or grep commands but these are not perfect utilities to Parse JSON Data because we have to write more complex logic to work with JSON Data,
