jq -组合来自不同键的数据

Question

我有这个json输出

{
"FileSystems": [
    {
        "CreationToken": "CreationToken1",
        "OwnerId": "OwnerId1",
        "SizeInBytes": {
            "Timestamp": 1552377599.0,
            "Value": 1550721024
        },
        "Name": "Name1",
        "NumberOfMountTargets": 3,
        "FileSystemId": "fs-1",
        "LifeCycleState": "available",
        "CreationTime": 1550506468.0,
        "PerformanceMode": "generalPurpose"
    },
    {
        "CreationToken": "CreationToken2",
        "OwnerId": "OwnerId2",
        "SizeInBytes": {
            "Timestamp": 1552377599.0,
            "Value": 2390339584
        },
        "Name": "Name2",
        "NumberOfMountTargets": 3,
        "FileSystemId": "fs-2",
        "LifeCycleState": "available",
        "CreationTime": 1547663741.0,
        "PerformanceMode": "generalPurpose"
    }
]
}

通过使用此命令

aws efs describe-file-systems | jq -r ".FileSystems[] | .SizeInBytes.Value"

我可以收到NFS大小值：

1550725120
2390339584

但是我需要获得一个带有文件系统名称的输出，所以它应该是这样的：

Name1: 1550725120
Name2: 2390339584

我该怎么做呢？

Answer 1

可以使用string interpolation，如下所示：

jq -r ".FileSystems[] | \"\(.Name) \(.SizeInBytes.Value)\""
