title: How do I list all Amazon RDS DB Instance Classes for DB engine oracle-ee using AWS CLI
body: <p>I am trying to list all DB instance class in a format something like this:</p>
  
  <p><code>db.t1.micro db.m1.small db.m1.medium db.m1.large db.m1.xlarge db.m2.xlarge db.m2.2xlarge db.m2.4xlarge db.m3.medium db.m3.large db.m3.xlarge db.m3.2xlarge db.m4.large db.m4.xlarge db.m4.2xlarge db.m4.4xlarge db.m4.10xlarge db.r3.large db.r3.xlarge db.r3.2xlarge db.r3.4xlarge db.r3.8xlarge db.t2.micro  db.t2.small db.t2.medium db.t2.large</code>.</p>
  
  <p>There is a command that list all of the db instance types but I can find a way to <code>--query</code> it.</p>
  
  <pre><code>aws rds describe-orderable-db-instance-options  --engine oracle-ee --engine-version 12.1.0.2.v8 --license-model bring-your-own-license --output table
  </code></pre>
  
  <p>Output of this command is huge and I can't help to sort this out.</p>
