使用jq指望多个级别

Question

我们发现了一些与感染有关的域名.现在我们在.json文件中有一个DNS名称列表,我想生成一个汇总输出,显示:用户列表,他们访问的唯一域,总计数.如果我也可以计算每个域名的奖励积分.

以下是该文件的示例:

{"machine": "possible_victim01", "domain": "evil.com", "timestamp":1435071870}
{"machine": "possible_victim01", "domain": "evil.com", "timestamp":1435071875}
{"machine": "possible_victim01", "domain": "soevil.com", "timestamp":1435071877}
{"machine": "possible_victim02", "domain": "bad.com", "timestamp":1435071877}
{"machine": "possible_victim03", "domain": "soevil.com", "timestamp":1435071879}

理想情况下,我希望输出类似于:

{"possible_victim01": "total": 3, {"evil.com": 2, "soevil.com": 1}}
{"possible_victim02": "total": 1, {"bad.com": 1}}
{"possible_victim03": "total": 1, {"soevil.com": 1}}

我很乐意接受:

{"possible_victim01": "total": 3, ["evil.com", "soevil.com"]}
{"possible_victim02": "total": 1, ["bad.com"]}
{"possible_victim03": "total": 1, ["soevil.com"]}

我可以获得每个用户的总记录数,但是我丢失了域名列表:

cat sample.json | jq -s 'group_by(.machine) | map({machine:.[0].machine,domain:.[0].domain, count:length}) '
[{"machine": "possible_victim01", "domain": "evil.com", "count": 3},  
{"machine": "possible_victim02", "domain": "bad.com", "count": 1},
{"machine": "possible_victim03", "domain": "soevil.com", "count": 1}]

这篇文章描述了如何解决问题的后半部分...... JQ Aggregations和Crosstabs.我还没有发现任何描述上半场的内容,

{"machine": "possible_victim01", "domain": "evil.com", "count":2}
{"machine": "possible_victim01", "domain": "soevil.com", "count":1}
{"machine": "possible_victim02", "domain": "bad.com", "count":1}
{"machine": "possible_victim03", "domain": "soevil.com", "count":1}

您需要执行group_by两次,一次按机器名称分组,然后进行子分组以获取每个域的子计数.

jq查询:

group_by(.machine) | map({
    "machine": .[0].machine, 
    "total":length, 
    "domains": (group_by(.domain) | map({
        "key":.[0].domain, 
        "value":length}) | from_entries
    )
})

示例输出:

{
  "machine": "possible_victim01",
  "total": 3,
  "domains": {
    "evil.com": 2,
    "soevil.com": 1
  }
}
{
  "machine": "possible_victim02",
  "total": 1,
  "domains": {
    "bad.com": 1
  }
}
{
  "machine": "possible_victim03",
  "total": 1,
  "domains": {
    "soevil.com": 1
  }
}
