# Parent
Parent simply returns the parent nodes of the matching nodes.
{% hint style="warning" %}
Note that versions prior to 4.18 require the 'eval/e' command to be specified. 
`yq e <exp> <file>`
{% endhint %}
## Simple example
Given a sample.yml file of:
```yaml
a:
nested: cat
```
then
```bash
yq '.a.nested | parent' sample.yml
```
will output
```yaml
nested: cat
```
## Parent of nested matches
Given a sample.yml file of:
```yaml
a:
fruit: apple
name: bob
b:
fruit: banana
name: sam
```
then
```bash
yq '.. | select(. == "banana") | parent' sample.yml
```
will output
```yaml
fruit: banana
name: sam
```
## No parent
Given a sample.yml file of:
```yaml
{}
```
then
```bash
yq 'parent' sample.yml
```
will output
```yaml
```
