[ aws . elasticache ]



Modifies the parameters of a cache parameter group. You can modify up to 20 parameters in a single request by submitting a list parameter name and value pairs.

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.


--cache-parameter-group-name <value>
--parameter-name-values <value>
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]


--cache-parameter-group-name (string)

The name of the cache parameter group to modify.

--parameter-name-values (list)

An array of parameter names and values for the parameter update. You must supply at least one parameter name and value; subsequent arguments are optional. A maximum of 20 parameters may be modified per request.

Shorthand Syntax:

ParameterName=string,ParameterValue=string ...

JSON Syntax:

    "ParameterName": "string",
    "ParameterValue": "string"

--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.

See 'aws help' for descriptions of global parameters.
