title: Possible: AWS CLI Describe Not Equal To
body: <p>I am currently using the AWS CLI to select instances and I have the following query:</p>
  
  <pre><code>aws ec2 describe-instances --filter "Name=instance.group-name,Values=my-cluster" "Name=instance-state-name,Values=running,pending,stopped" 'Name=tag:Name, Values=someInstance*'
  </code></pre>
  
  <p>This works and selects all the instances that start with someInstance. </p>
  
  <p>However, I want to do the opposite, select all other instances that do NOT match this. I have tried using a regex but this doesn't work:</p>
  
  <pre><code>aws ec2 describe-instances --filter "Name=instance.group-name,Values=my-cluster" "Name=instance-state-name,Values=running,pending,stopped" 'Name=tag:Creater, Values=^(?!someInstance).*$'
  </code></pre>
  
  <p>Is this possible?</p>
