What you'll learn:
- Parsing JSON Data with Jq Command
- Identify, Field and Iterator Filters
- Functions of Jq Command
- Usage of Jq Command in Shell Scripts
- Converting JSON Data into csv and tsv formats
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,
Its very easy to work with JSON Data using Jq Command. JQ supports filters, function, conditions, operators, and other language features.
