【中文标题】按最近的时间戳对数组中的对象数组进行排序，然后使用 jq 按每个数组的第一个对象的时间戳对外部数组进行排序

【英文标题】：Sort an array of objects within an array by most recent timestamp, and then sort the outer array by each array's first object's timestamp, using jq

【问题描述】：

使用jq，按照最近的时间戳对数组中的对象数组进行排序，然后按照每个数组的第一个对象的时间戳对外部数组进行排序。

这是 JSON 数据的一个示例，位于我被卡住的 jq 管道阶段。

我尝试过的一切都以这样的错误告终，

jq: error (at <stdin>:8): Cannot index string with string "created_at"

【参考方案1】：

也许是这个？

jq '.[] |= sort_by(.created_at) | sort_by(.[].created_at)'
