List all parameters in AWS SSM Parameter Store

How do I list all parameters in the AWS Systems Manager (SSM) Parameter Store? I am using the AWS CLI.

I can store them with aws ssm put-parameter. I can fetch them with aws ssm get-parameter. I can list all documents with aws ssm list-documents, but I do not see a corresponding list-parameters function.

I think what you want is

    aws ssm describe-parameters
