如何使用jq输出JSONL(每行一个独立的JSON对象) [英] How to use jq to output JSONL (one independent JSON object per line)

问题描述

我的要求听起来微不足道，但我找不到解决方法.作为输入，我有一个JSON对象数组:

My request sounds trivial but I could not find a way to do it. I have as input an array of JSON objects:

[
    {
        "foo": 1,
        "bar": 2
    },
    {
        "foo": 3,
        "bar": 4
    },
    (...)
]

并且我想要输出相同的JSONL版本，也就是每行一个对象，而不是数组:

and I want as output the JSONL version of the same, aka one object per line, not an array:

    { "foo": 1, "bar": 2 }
    { "foo": 3, "bar": 4 }
    (...)

这与使用--compact-output 不相同，因为那样可以保留数组并给我:

This is not the same as using --compact-output, as that would preserve the array and give me:

    [ { "foo": 1, "bar": 2 }, { "foo": 3, "bar": 4 }, (...) ]

谢谢.

推荐答案

原始问题的答案是将过滤器.[]与-c命令行选项一起使用:

The answer to the original question is to use the filter .[] together with the -c command-line option:

$ jq -c '.[]'
