尝试使用jq在一行上格式化json数据答案

【问题标题】：Trying to use jq to format json data on one line尝试使用jq在一行上格式化json数据
【发布时间】：2021-06-01 22:06:20
【问题描述】：

下面的输出是我的 curl 查询的 json 输出。我尝试了多个 jq 过滤器来尝试获得看起来像的结果 interfaceId、供应商、地址

从我的 json/curl 输出，应用“jq”过滤器后，我只得到：

eth1

eth1

eth1

Apple

BB Technologies (Limited)

null

Ipaddress#1

Ipaddress#2

Ipaddress#3

我希望输出是：

interfaceId,vendor,addresses curl/json 返回的每条记录

有人可以帮我解决这个问题

标签： json export-to-csv jq

【解决方案1】：

jq -r '.macTable[] | [.interfaceId, .vendor, .addresses[]] | @csv' x.json

输出类似于

"eth1","Apple","192.168.5.101"
"eth1","BB Technologies (Limited)","192.xxx.x.1"
"eth1",,"192.xxx.x.100"
