jq

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

  • Execute a specific expression (print a colored and formatted JSON output):

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

  • Execute a specific script:

{{cat path/to/file.json}} | jq --from-file {{path/to/script.jq}}

  • Pass specific arguments:

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

  • Print specific keys:

{{cat path/to/file.json}} | jq '{{.key1, .key2, ...}}'

  • Print specific array items:

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

  • Print all array/object values:

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

  • Add/remove specific keys:

{{cat path/to/file.json}} | jq '. {{+|-}} {{{"key1": "value1", "key2": "value2", ...}}}'
