Question

我有一个具有以下格式的json文件。如果.children []。type ==“ environmentApprovalTask”和.children []。role.name ==“ GCM批准人”并输出，我想在propDefs []中添加元素{“ test”：“ 2”}到新文件。我希望整个文件的内容都已修改。.children[]数组可能并不总是包含3个元素。

        "name": "Manager Approver",
        "isDeletable": true
      }
    }
  ]
}

我最后一次尝试使用代码

cat file.json |jq '.|.children[]| select(.type=="envApprovalTask")|select(.role.name=="Approver") |.propDefs[.profDefs|length] |= .+ {"test" : "2"}'

这仅产生修改后的元素，没有产生整个文件作为输出。请帮助我如何获得所需的输出。

有关jq中的复杂分配的TIL。这实际上有效：

(.children[] | select(.type=="envApprovalTask" and .role.name=="Approver") | .propDefs) |= .+[{"test":"2"}]

与您的版本唯一的区别是作业的左侧带有括号。

jQuery有条件地在json数组中添加元素并打印整个修改后的文件
