Description: 

Bashing JSON is an introductory hands-on course in jq, a command line, stream-processing tool designed to parse and transform structured data (think sed for JSON). Learn how to use shell tools to interact with APIs from AWS, GitHub, and Librato, to retrieve information as well as build JSON objects and post them from the command line without the need for a general purpose programming language. 

Note: Attendees should bring a laptop with Vagrant installed. 

Who should attend: 

Shell-adept operations folks who wish they had a better means of manipulating JSON formatted output from web APIs. 

Take back to work: 

Attendees will take away practical experience with writing shell scripts and one-liners that interact with live web services APIs. 

Topics include: 
  • Writing reliable shell scripts around cURL
  • Reformatting JSON output from a web API to make it human readable
  • Exploring API output by filtering on keys
  • Filtering portions of JSON
  • If/Else loops and key selection
  • Creating new JSON objects by selecting parts of an inbound stream
  • Creating new JSON objects from free-form text input
