json - Bash JQ 在 JSON 文件中获取多个值问题

Question

我正在尝试解析 JSON 文件以获取多个值。我知道如何解析数组 (.info.file.hashes[]) 中的特定值(“A”/“B”/“C”)。

例如:当对文件 b.json

发出以下命令时

jq -r '.info.file.hashes[] | select(.name == ("A","B","C")).value' b.json

结果:

f34d5f2d4577ed6d9ceec516c1f5a744
66031dad95dfe6ad10b35f06c4342faa
9df25fa4e379837e42aaf6d05d92012018d4b659  

其中b.json:

{
  "Finish": 1475668827,
  "Start": 1475668826,
  "info": {
    "file": {
      "Score": 4,
      "file_subtype": "None",
      "file_type": "Image",
      "hashes": [
        {
          "name": "A",
          "value": "f34d5f2d4577ed6d9ceec516c1f5a744"
        },
        {
          "name": "B",
          "value": "66031dad95dfe6ad10b35f06c4342faa"
        },
        {
          "name": "C",
          "value": "9df25fa4e379837e42aaf6d05d92012018d4b659"
        },
        {
          "name": "D",
          "value": "4a51cc531082d216a3cf292f4c39869b462bf6aa"
        },
        {
          "name": "E",
          "value": "e445f412f92b25f3343d5f7adc3c94bdc950601521d5b91e7ce77c21a18259c9"
        }
      ],
      "size": 500
    }
  }
}

现在，如何使用“完成”、“开始”和散列值获取多个值？我试过发出命令。

 jq -r '.info.file.hashes[] | select(.name == ("A","B","C")).value','.Finish','.Start' b.json 

我得到的结果是:

f34d5f2d4577ed6d9ceec516c1f5a744
null
66031dad95dfe6ad10b35f06c4342faa
null
9df25fa4e379837e42aaf6d05d92012018d4b659
null
null
null

预期结果:

f34d5f2d4577ed6d9ceec516c1f5a744
66031dad95dfe6ad10b35f06c4342faa
9df25fa4e379837e42aaf6d05d92012018d4b659
1475668827
1475668826

Answer 1

从字面上看只是下载并阅读手册

尝试

jq '(.info.file.hashes[] |select(.name == ("A","B","C")).value), .Finish, .Start' b.json

"f34d5f2d4577ed6d9ceec516c1f5a744"
"66031dad95dfe6ad10b35f06c4342faa"
"9df25fa4e379837e42aaf6d05d92012018d4b659"
1475668827
1475668826

请注意用于将管道与 Finish 和 Start 值分开分组的括号。
