list-ledgers

Description

Returns an array of ledger summaries that are associated with the current AWS account and Region.

This action returns a maximum of 100 items and is paginated so that you can retrieve all the items by calling ListLedgers multiple times.

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.

Synopsis

  list-ledgers
[--max-results <value>]
[--next-token <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--max-results (integer)

The maximum number of results to return in a single ListLedgers request. (The actual number of results returned might be fewer.)

--next-token (string)

A pagination token, indicating that you want to retrieve the next page of results. If you received a value for NextToken in the response from a previous ListLedgers call, then you should use that value as input here.

--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.

            "State": "ACTIVE",
            "CreationDateTime": 1568839243.951,
            "Name": "myExampleLedger"
        },
        {
            "State": "ACTIVE",
            "CreationDateTime": 1568839543.557,
            "Name": "myExampleLedger2"
        }
    ]
