[ aws . ssm ]



Query a list of all parameters used by the AWS account.

See also: AWS API Documentation


--name <value>
[--with-decryption | --no-with-decryption]
[--max-results <value>]
[--next-token <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]


--name (string)

The name of a parameter you want to query.

--with-decryption | --no-with-decryption (boolean)

Return decrypted values for secure string parameters. This flag is ignored for String and StringList parameter types.

--max-results (integer)

The maximum number of items to return for this call. The call also returns a token that you can specify in a subsequent call to get the next set of results.

--next-token (string)

The token for the next set of items to return. (You received this token from a previous call.)

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.
