update-function-definition

Description

Updates a Lambda function definition.

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.

Synopsis

  update-function-definition
--function-definition-id <value>
[--name <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--function-definition-id (string) The ID of the Lambda function definition.

--name (string) The name of the definition.

--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. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--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.
