A JSON processor that uses a domain-specific language (DSL). More information: https://jqlang.github.io/jq/manual/.

jq '.' {{/path/to/file.json}}

• Execute a specific script:

• Pass specific arguments:

{{cat path/to/file.json}} | jq {{--arg "name1" "value1" --arg "name2" "value2" ...}} '{{. + $ARGS.named}}'

• Create new JSON object via old JSON objects from multiple files:

{{cat path/to/multiple_json_file_*.json}} | jq '{{{newKey1: .key1, newKey2: .key2.nestedKey, ...}}}'

• Print specific array items:

{{cat path/to/file.json}} | jq '{{.[index1], .[index2], ...}}'

• Print all array/object values:

{{cat path/to/file.json}} | jq '.[]'

{{cat path/to/file.json}} | jq '.[] | select((.key1=="value1") and .key2=="value2")'
