Key benefits

  • Beginner’s level guide to explain Jq command using Bash Shell Scripts with detailed explanation

Description

Nowadays, DevOps automation is more into REST API usage, and REST API response is JSON. So, to implement bash shell scripts using REST APIs, you must know how to parse the response of REST API (that is, parse JSON data). Jq is a program developed to filter JSON data. You can consider Jq like sed, awk, or grep program but designed specifically for filtering JSON data. Jq supports filters, conditions, operators, and other language features. While the creation and understanding of JSON data are effortless due to its human-readable format, JSON data parsing is still a very complicated task to achieve if done manually. Instead, you can use programs like Jq to parse JSON data in minutes. In this course, you will see the usage of the Jq command in Bash Shell Scripts, followed by filters and options to work with JSON objects. After that, you will look at the simple usage of the Jq command in Shell Scripts and start working with JSON arrays using the index concept. Next, you will be constructing objects and arrays with and without inputs and the usage of the -n option in Jq Command. Finally, you will study the Jq functions. By the end of this course, you will have learned and gained the requisite confidence to work with the Jq Command using Bash Shell scripting in detail. All the resource files are added to the GitHub repository at: https://github.com/PacktPublishing/Jq-Command-Tutorials-for-Bash-Shell-Scripting

What you will learn

Can I download the code files for Early Access titles? Chevron down icon Chevron up icon

We try to ensure that all books in Early Access have code available to use, download, and fork on GitHub. This helps us be more agile in the development of the book, and helps keep the often changing code base of new versions and new technologies as up to date as possible. Unfortunately, however, there will be rare cases when it is not possible for us to have downloadable code samples available until publication.

When we publish the book, the code files will also be available to download from the Packt website.

How accurate is the publication date? Chevron down icon Chevron up icon

The publication date is as accurate as we can be at any point in the project. Unfortunately, delays can happen. Often those delays are out of our control, such as changes to the technology code base or delays in the tech release. We do our best to give you an accurate estimate of the publication date at any given time, and as more chapters are delivered, the more accurate the delivery date will become.

How will I know when new chapters are ready? Chevron down icon Chevron up icon

We'll let you know every time there has been an update to a course that you've bought in Early Access. You'll get an email to let you know there has been a new chapter, or a change to a previous chapter.

As we go through the process of developing a course, 99% of it can be ready but we can't publish until that last 1% falls in to place. Early Access helps to unlock the potential of our content early, to help you start your learning when you need it most. You not only get access to every chapter as it's delivered, edited, and updated, but you'll also get the finalized, DRM-free product to download in any format you want when it's published.
