Using jq
Expert guidance for processing JSON on the command line with jq.
Quick Start
For immediate help, identify your task type and consult the relevant reference:
| Working On | Reference File | Key Topics |
|---|---|---|
| Filter syntax, arrays, objects | core-filters | Access, select, map, conditionals, built-ins |
| Jira CLI, GitHub CLI, curl | cli-integrations | Tool-specific JSON patterns |
| Shell variables, TSV, CSV | output-formatting | -r, @tsv, @csv, null handling |
Core Principles
Use -e for Error Detection
Always use jq -e when checking for values — it sets exit code 1 when the result is false or null, enabling proper error handling in shell pipelines.
