LastModifiedDateCondition -> (structure)

If provided, this structure defines a date range for matching Amazon S3 objects based on their LastModifiedDate attribute in Amazon S3.

Expression -> (string)

The expression which includes condition names followed by substitution variables, possibly grouped and combined with other conditions. For example, "(starts_with :prefix1 or starts_with :prefix2) and (ends_with :suffix1 or ends_with :suffix2)". Substitution variables should start with ':' symbol.

--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.

Name -> (string)
