Options
| Name | Description |
|---|---|
--name <string> | The name of the ledger |
--block-address <structure> | The location of the block that you want to request. An address is an Amazon Ion structure that has two fields: strandId and sequenceNo. For example: {strandId:"BlFTjlSXze9BIh1KOszcE3",sequenceNo:14} |
--digest-tip-address <structure> | The latest block location covered by the digest for which to request a proof. An address is an Amazon Ion structure that has two fields: strandId and sequenceNo. For example: {strandId:"BlFTjlSXze9BIh1KOszcE3",sequenceNo:49} |
--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 |
