Question

我需要获取该公司创建的亚马逊图像列表。这将放入一个变量，我将其转换为csv格式并输出到电子表格。

我需要考虑映像ID和附加的卷的大小。

如果我尝试执行以下命令：

cat ab-prod-images.json |  jq -r '.Images[] | [.ImageId, ([.BlockDeviceMappings[].Ebs.VolumeSize])] | @csv'

这是我得到的错误：

jq: error (at <stdin>:53471): array ([100,5,10,2...) is not valid in a csv row

我将该命令的输出存储在一个变量中，该变量将用于输出到电子表格。

我想要的是一个用逗号分隔的卷大小列表，该列表显示在电子表格的同一单元格中。

这是我正在使用的json的示例：

如何获取VolumeSizes列表以放入要创建的电子表格的同一单元格中？

Answer 1

@csv的输入必须是平面数组，但是您的过滤器（.Images[] | [.ImageId, ([.BlockDeviceMappings[].Ebs.VolumeSize])]）会生成嵌套数组，因为您将体积大小放入了子数组（ [ {{ 1}} ] ）：

.BlockDeviceMappings[].Ebs.VolumeSize

因此，请改用以下命令。

$ jq -rc '.Images[] | [.ImageId, ([.BlockDeviceMappings[].Ebs.VolumeSize])]' file.json 
["ami-000bd263d51e443f2",[100,5,10,20,40,30,5]]

产生：

jq -r '.Images[] | [ .ImageId, .BlockDeviceMappings[].Ebs.VolumeSize ] | @csv' ab-prod-images.json

数字列表对于jq
