每行一个 json object 与来自大型 json 文件的 jq

Question

Here is my json file:

[
  {
    "name": "1"
  },
  {
    "name": "2"
  },
  {
    "name": "3"
  },
  {
    "name": "4"
  }
]

i would like to get all object in a file one by line:

{"name":"1"}
{"name":"2"}
{"name":"3"}
{"name":"4"}

and my file is very big and i'am using the stream option.

Here is my attempt so far:

jq --stream -c '.[]' car.json > result.json

but it gives me:

[0,"name"]
"1"
[1,"name"]
"2"

This topic is covered in the jq FAQ . For the situation you describe you might be able to use the simpler of the two possibilities given there:

jq -cn --stream 'fromstream(1|truncate_stream(inputs))'
