使用 jq 和 awk 拆分大型 JSON 文件

我有一个很大的文件叫

Metadata_01.json

它由以下 struct 块组成:

[
 {
  "Participant_id": "P04_00001",
  "no_of_people": "Multiple",
  "apparent_gender": "F",
  "geographic_location": "AUS",
  "ethnicity": "Caucasian",
  "capture_device_used": "iOS 14",
  "camera_orientation": "Portrait",
  "camera_position": "Side View",
  "indoor_outdoor_env": "Indoors",
  "lighting_condition": "Bright",
  "Occluded": 1,
  "category": "Two Person",
  "camera_movement": "Still",
  "action": "No action",
  "indoor_outdoor_in_moving_car_or_train": "Indoor",
  "daytime_nighttime": "Nighttime"
 },
 {
  "Participant_id": "P04_00002",
  "no_of_people": "Single",
  "apparent_gender": "M",
  "geographic_location": "AUS",
  "ethnicity": "Caucasian",
  "capture_device_used": "iOS 14",
  "camera_orientation": "Portrait",
  "camera_position": "Frontal View",
  "indoor_outdoor_env": "Outdoors",
  "lighting_condition": "Bright",
  "Occluded": "None",
  "category": "Animals",
  "camera_movement": "Still",
  "action": "Small action",
  "indoor_outdoor_in_moving_car_or_train": "Outdoor",
  "daytime_nighttime": "Daytime"
 },

以此类推.数以千计.

我正在使用以下命令:

jq -cr '.[]' Metadata_01.json | awk '{print > (NR ".json")}'

它在某种程度上完成了预期的工作.

From large file that is structured like this个

I am getting tons of files that named like this个

And structure like this (in one line)

我需要用"Participant_id"来命名每个json文件，而不是这些结果(例如，p04_00002.json) 并且我希望保留json struct ，使其与每个文件类似

{
  "Participant_id": "P04_00002",
  "no_of_people": "Single",
  "apparent_gender": "M",
  "geographic_location": "AUS",
  "ethnicity": "Caucasian",
  "capture_device_used": "iOS 14",
  "camera_orientation": "Portrait",
  "camera_position": "Frontal View",
  "indoor_outdoor_env": "Outdoors",
  "lighting_condition": "Bright",
  "Occluded": "None",
  "category": "Animals",
  "camera_movement": "Still",
  "action": "Small action",
  "indoor_outdoor_in_moving_car_or_train": "Outdoor",
  "daytime_nighttime": "Daytime"
 }

我应该对上面的命令进行哪些调整才能实现这一点？ 或者也许有一个更简单的方法来做到这一点？谢谢!
