How do I search for a boolean using yq to create entries?

edit

To search for a boolean using yq to create entries, you can use the following syntax:

yq eval 'select(.boolean_field == true)' input.yaml

This will search for all entries in input.yaml where the boolean_field is equal to true and output the results to the console. If you want to create new entries based on this search, you can chain this command with a | and then specify the new entries you want to add:

yq eval 'select(.boolean_field == true) | {name: "New Entry", value: 42}' input.yaml

This will create a new entry in input.yaml for each existing entry where boolean_field is equal to true, with the name field set to "New Entry" and the value field set to 42.
