从文本文件中提取 ID

Question

我在下面有一个文本文件

 {
  "data": {
    "assigned-entity-id": null,
    "assigned-entity-type": null,
    "availability-domain": null,
    "compartment-id": "ocid1.tenancy.oc1..dgfmmnusmgibmkdomuijsngimimfimfgiufmgifmdsfsdsgsmgsifmg",
    "defined-tags": {
      "Oracle-Tags": {
        "CreatedBy": "abcd@gmail.com",
        "CreatedOn": "2021-03-20T13:26:04.662Z"
      }
    },
    "display-name": "ABC",
    "freeform-tags": {},
    "id": "ocid1.database.oc1.cd-south-1.amaaaaaago5rdtya6mmvwjfdpdebz7twdxlfdsdssssssaaaaaaadddddd",
    "ip-address": "1.1.1.1",
    "lifecycle-state": "AVAILABLE",
    "lifetime": "XXXXXXX",
    "private-ip-id": null,
    "public-ip-pool-id": null,
    "scope": "REGION",
    "time-created": "2021-03-20T13:26:04.748000+00:00"
  },
  "etag": "cdsssss"
}
{
  "data": {
    "assigned-entity-id": null,
    "assigned-entity-type": null,
    "availability-domain": null,
    "compartment-id": "ocid1.tenancy.oc1..dgfmmnusmgibmkdomuijsngimimfimfgiufmgifmdsfsdsgsmgsifmg",
    "defined-tags": {
      "Oracle-Tags": {
        "CreatedBy": "abcd@gmail.com",
        "CreatedOn": "2021-03-20T13:26:09.523Z"
      }
    },
    "display-name": "ASD",
    "freeform-tags": {},
    "id": "ocid1.database.oc1.cd-south-1.amaaaaaago5rdtya6mmvwjfdpdezzzzzzzzzzzzzzzzzzzddddddddddddddd",
    "ip-address": "2.2.2.2",
    "lifecycle-state": "AVAILABLE",
    "lifetime": "XXXXXXX",
    "private-ip-id": null,
    "public-ip-pool-id": null,
    "scope": "REGION",
    "time-created": "2021-03-20T13:26:09.583000+00:00"
  },
  "etag": "dfreeeee"
}

我想要的输出为 ocid1.database.oc1.cd-south-1.amaaaaaago5rdtya6mmvwjfdpdebz7twdxlfdsdssssssaaaaaaadddddd ocid1.database.oc1.cd-south-1.amaaaaaagozzzzzzvdddddddddddddddssssssaaaaaaadddddd

我尝试在 google 上搜索，但无法获得任何特定选项。

任何人都可以建议任何 grep、awk 或任何 usnix 命令来获取输出

Answer 1

最直接的答案是不要为此尝试使用 grep、sed、awk 等 - 即使他们会这样做，您最终肯定会做出假设并且不得不不断地改组代码。

您可以使用 python 中的内置 json 模块或像jq这样的专用 CLI 工具来完成。

jq 示例：

% cat ids.txt | jq '.data.id'
"ocid1.database.oc1.cd-south-1.amaaaaaago5rdtya6mmvwjfdpdebz7twdxlfdsdssssssaaaaaaadddddd"
"ocid1.database.oc1.cd-south-1.amaaaaaago5rdtya6mmvwjfdpdezzzzzzzzzzzzzzzzzzzddddddddddddddd"

蟒蛇示例：

% cat ids.txt | python3 -c "import sys, json; print(json.load(sys.stdin)['data']['id'])"
ocid1.database.oc1.cd-south-1.amaaaaaago5rdtya6mmvwjfdpdebz7twdxlfdsdssssssaaaaaaadddddd
ocid1.database.oc1.cd-south-1.amaaaaaago5rdtya6mmvwjfdpdezzzzzzzzzzzzzzzzzzzddddddddddddddd
