**Example 2: To describe a specified number of launch configurations**

To return a specific number of launch configurations, use the ``--max-items`` option. ::

    aws autoscaling describe-launch-configurations \
        --max-items 1

If the output includes a ``NextToken`` field, there are more launch configurations. To get the additional launch configurations, use the value of this field with the ``--starting-token`` option in a subsequent call as follows. ::

    aws autoscaling describe-launch-configurations \
        --starting-token Z3M3LMPEXAMPLE
