Explore the process of writing a script using bash, jq, and the btp CLI in this 57-minute tutorial from SAP. Learn how to leverage JSON format output from the btp CLI, create a new script file, explore role collections JSON with JQ playground, and pipe role collection lists into fzf. Discover alternative methods for selecting role collections, add role template app IDs to outputs, and understand the proper use of xargs with functions and scripts. Gain practical insights into building useful scripts around the btp CLI while covering topics such as asynchronous fixers, escaped newlines, and Unix-style parsing techniques.
