This operator recursively matches all children nodes given of a particular element, including that node itself. This is most often used to apply a filter recursively against all matches, for instance to set the `style` of all nodes in a yaml doc: ```bash yq eval '.. style= "flow"' file.yaml ``` ## Aliases are not traversed Given a sample.yml file of: ```yaml a: &cat c: frog b: *cat ``` then ```bash yq eval '[..]' sample.yml ``` will output ```yaml - a: &cat c: frog b: *cat - &cat c: frog - frog - *cat ``` ## Merge docs are not traversed Given a sample.yml file of: ```yaml foo: &foo a: foo_a thing: foo_thing c: foo_c bar: &bar b: bar_b thing: bar_thing c: bar_c foobarList: b: foobarList_b !!merge <<: - *foo - *bar c: foobarList_c foobar: c: foobar_c !!merge <<: *foo thing: foobar_thing ``` then ```bash yq eval '.foobar | [..]' sample.yml ``` will output ```yaml - c: foobar_c !!merge <<: *foo thing: foobar_thing - foobar_c - *foo - foobar_thing ```
