You can specify a filter to scope the results to instance types that have a specific characteristic. The following `describe-instance-types` example lists the instance types that support hibernation.
```
aws ec2 describe-instance-types \
--filters Name=hibernation-supported,Values=true --query 'InstanceTypes[*].InstanceType'
```
Output:
```
