DescribeJob与 S Amazon DK 或命令行工具配合使用

以下命令检索名为 my-vault 的文件库中有关库存检索任务的信息：

aws glacier describe-job --account-id - --vault-name my-vault --job-id zbxcm3Z_3z5UkoroF7SuZKrxgGoDc3RloGduS7Eg-RO47Yc6FxsdGBgf_Q2DK5Ejh18CnTS5XW4_XqlNHS61dsO4CnMW

输出：

{
    "InventoryRetrievalParameters": {
        "Format": "JSON"
    },
    "VaultARN": "arn:aws:glacier:us-west-2:0123456789012:vaults/my-vault",
    "Completed": false,
    "JobId": "zbxcm3Z_3z5UkoroF7SuZKrxgGoDc3RloGduS7Eg-RO47Yc6FxsdGBgf_Q2DK5Ejh18CnTS5XW4_XqlNHS61dsO4CnMW",
    "Action": "InventoryRetrieval",
    "CreationDate": "2015-07-17T20:23:41.616Z",
    "StatusCode": "InProgress"
}

任务 ID 可以在 aws glacier initiate-job 和 aws glacier list-jobs 的输出中找到。Amazon Glacier 在执行操作时需要一个账户 ID 参数，但您可以使用连字符来指定正在使用的账户。

示例 1：返回指定任务的详细信息。任务成功完成后，可以使用 read-GC JobOutput cmdlet 将任务的内容（档案或清单列表）检索到本地文件系统。

Get-GLCJob -VaultName myvault -JobId "op1x...JSbthM"

输出：
