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
|
|
