Update JSON file using Terminal or bash script

Automating JSON file updates can save a lot of manual effort when working with configuration files, API data, or structured data in Linux or OS X environments. This guide explains how to automate JSON updates using Bash scripts and the jq command-line JSON processor. jq is a lightweight and flexible tool that can be installed using a package manager. To read JSON values, jq can be used with the dot notation, and to update JSON values, jq can be used with the --arg or --argjson options. A sample JSON file can be updated by reading its values and then updating them using jq. For example, to update the version field, the jq command can be used with the --arg option to update the field dynamically. A Bash script can be created to automate updates to multiple fields at once. The script can use jq to update the version and add a new dependency. The script can be made executable and run to update the JSON file automatically. The script can also be modified to automate version increases by reading the current version, increasing the minor version by one, and updating the version in the JSON file. Finally, the script can be added to a CI/CD pipeline to automate configuration updates before deployment. This can be done by adding a step that runs the Bash script in the pipeline process. Automating JSON file updates with Bash and jq can save a lot of time and headache by reducing manual intervention. This process can streamline workflows and reduce errors.
