使用 JQ 將同一文件中的多個 JSON 數組合並為一個 JSON 數組

Question

我有一個文件，其中包含多個單獨的 JSON arrays，我想將其組合（並刪除空數組）到單個 JSON 數組中

輸入

[]
[]
[
    [
        [
            "asdfsdfsdf",
            "CCsdfnceR1",
            "running",
            "us-east-1a",
            "34.6X.7X.2X",
            "10.75.170.118"
        ]
    ]
]
[]
[]
[
    [
        [
            "tyutyut",
            "CENTOS-BASE",
            "stopped",
            "us-west-2b",
            null,
            "10.87.159.249"
        ]
    ],
    [
        [
            "tyutyut",
            "dfgdfg-TEST",
            "stopped",
            "us-west-2b",
            "54.2X.8.X8",
            "10.87.159.247"
        ]
    ]
]

需要 output

[
    [
        "asdfsdfsdf",
        "CCsdfnceR1",
        "running",
        "us-east-1a",
        "34.6X.7X.2X",
        "10.75.170.118"
    ],
    [
        "tyutyut",
        "CENTOS-BASE",
        "stopped",
        "us-west-2b",
        null,
        "10.87.159.249"
    ],
    [
        "tyutyut",
        "dfgdfg-TEST",
        "stopped",
        "us-west-2b",
        "54.2X.8.X8",
        "10.87.159.247"
    ]
]

提前致謝

Answer 1

這僅選擇非空 arrays 的元素都不是數組，並將它們放入數組中：

jq -n '[ inputs | .. | select(type=="array" and .!=[] and all(.[]; type!="array")) ]' file

Answer 2

確切的要求對我來說不是太清楚，但是使用以下def會產生預期的結果，並且可能會因為它是遞歸的而引起人們的興趣：

def peel:
  if type == "array"
  then if length == 0 then empty
       elif length == 1 and (.[0] | type) == "array" then .[0] | peel
       elif all(.[]; type=="array") then .[] | peel
       else [.[] | peel]
       end
  else .
  end;

使用此def和以下“主”程序：

[inputs | peel]

使用 -n 選項調用 jq 會產生預期的結果。
