Processing JSON in Bash with jq

Modern APIs, web services, and configuration files rely heavily on JSON, yet command-line environments often struggle to parse this format natively. Mastering the jq utility allows you to bridge the gap between shell scripts and structured data without relying on heavy programming languages. This text-only course guides you through the foundational concepts of JSON manipulation in Bash, helping you transition from manual text parsing to writing robust, automated scripts that extract, filter, and transform complex payloads with ease. You will learn to understand core JSON syntax and how jq interfaces with the command line, extract specific keys, nested objects, and array elements using precise filters, transform raw JSON data into clean formats or custom shell variables, handle missing keys, null values, and potential errors safely within your scripts, and combine jq with other command-line utilities using standard pipes. The course begins with fundamental terminology and basic query syntax before progressing to advanced filtering and practical scripting integration. This training is designed for system administrators, developers, and DevOps beginners who want to automate data workflows without any prior jq experience.
