我有一个.csv文件，其中有一个简短的变量列表，我需要从中创建一个.json文件。一切都工作得很好，但其中一个变量（$input[5]/“programNumber”）需要作为整数导入，我使用的脚本是用一组引号提取所有内容，这对前4个变量都很好。我只是对导入语法不够熟悉，无法理解它。先谢谢你的帮助。
以下是脚本：

jq -Rsn '
   {"services":
      [inputs
         | . / "\n"
         | (.[] | select(length > 0) | . / ",") as $input
         |   {
               "type": "mpeg2tsUdp",
               "sources":
               [
                  {
                    "address": $input[1],
                    "port": 2000,
                    "sourceAddresses":
                    [
                        $input[3]
                    ],
                    "programSelection":
                    {
                        "type": "PmtProgramNumber",
                        "programNumber": $input[5]
                    }
                  },
                  {
                    "address": $input[2],
                    "port": 2000,
                    "sourceAddresses":
                    [
                        $input[4]
                    ],
                    "programSelection":
                    {
                        "type": "PmtProgramNumber",
                        "programNumber": $input[5]
                    }
                  }
               ],
               "streams": [],
               "id": $input[0]
            }
         ],
         "id": "Inputs",
         "name": "Inputs"
      }
' <SourceList.csv

下面是.csv的内容：

FNCHD,239.194.208.9,239.194.216.9,10.110.208.9,10.110.216.9,23
MTV,239.194.208.216,239.194.216.216,10.110.208.216,10.110.216.216,702
AEHD,239.194.208.6,239.194.216.6,10.110.208.6,10.110.216.6,1
SLATE,239.1.1.1,239.1.2.1,10.100.1.1,10.100.2.1,3

这里是输出：

Anything I tried; including removing the quotes around \n and ",", either failed the script completely or changed nothing.

下面是使用tonumber一次的压缩版本：

jq -Rn '{
  services: [
    inputs | select(length > 0) / "," | {
      type: "mpeg2tsUdp",
      sources: [range(2) as $i | {
        address: .[1+$i],
        port: 2000,
        sourceAddresses: [.[3+$i]],
        programSelection: {
          type: "PmtProgramNumber",
          programNumber: .[5] | tonumber
        }
      }],
      streams: [],
      id: .[0]
    }
  ],
  id: "Inputs",
  name: "Inputs"
}' < SourceList.csv
