gutenfmt --output yaml

yaml

YAML is a good choice for handling the output programmatically with services and tools that emit or consume YAML-formatted strings.

For more advanced filtering, you can consider yq, a command line YAML processor. You can download it and find documentation at https://mikefarah.gitbook.io/yq/.

Example: name and value pairs to YAML

env | grep JAVA | gutenfmt --output yaml

JAVA_OPTS: -server -Xmx512m

Example: compact JSON to YAML
