           Location of the file with your AWS credentials. This value can be set by
           using the environment variable 'AWS_CREDENTIAL_FILE'.

        -C, --ec2-cert-file-path VALUE

        --headers
           If you are displaying tabular or delimited results, it includes the
           column headers. If you are showing xml results, it returns the HTTP
           headers from the service request, if applicable. This is off by default.

           Specify VALUE as the AWS Access Id to use.

           column-width form, while long shows all of the returned values delimited
           by a character. The xml is the raw return from the service, while quiet
           suppresses all standard output. The default is tabular, or 'show-table'.

        -U, --url VALUE
           This option will override the URL for the service call with VALUE. This
