` + "`--output`" + ` can be one of:
- **raw**:
- when querying for scalar values this will return a non-quoted version of the values

- **yaml**: formats the value at the given path as YAML
- **json**: formats the value at the given path as JSON
- **op**: formats the whole configuration as a 1Password item`,
