在shell脚本中提取json负载

我有一个像下面这样的文件。如您所见，花括号之间几乎没有行/内容。由于有多组打开和关闭的花括号，我想分别获取每行的花括号（{和}）之间的内容

示例文件： 预期结果：需要3个分开的数据块，位于花括号之间

---

有人能帮我吗？

如果您有一系列有效的JSON对象，您可以使用

jq

轻松、可靠地处理它们：

给定

文件.jsons

：

{
   "/tmp/©ƒ-4bf57ed2-velero/velero/templates/crds.yaml": [ ""
   ],
   "/tmp/velero-4bf57ed2-velero/velero/templates/deployment.yaml": [ ""
   ],
   "/tmp/velero-4bf57ed2-velero/velero/templates/restic-daemonset.yaml": [ ""
   ],
   "/tmp/velero-4bf57ed2-velero/velero/templates/secret.yaml": [ ""
   ]
 }
 {
   "/tmp/autoscaler-fb12fa7a-cluster-autoscaler/cluster-autoscaler/templates/deployment.yaml": [
     ".spec.replicas: '2' != '0'"
   ],
   "/tmp/autoscaler-fb12fa7a-cluster-autoscaler/cluster-autoscaler/templates/servicemonitor.yaml": [
     "error: the server doesn't have a resource type \"ServiceMonitor\"\n"
   ]
 }
 {
   "/tmp/metrics-server-1960953a-metrics-server-certs/raw/templates/resources.yaml": [
     "error: the server doesn't have a resource type \"Issuer\"\n",
     "error: the server doesn't have a resource type \"Certificate\"\n"
   ]
 }

例如，可以将每个对象重新格式化为一行：

$ jq -s -r 'map(@json) | join("\n")' < file.jsons 
{"/tmp/©ƒ-4bf57ed2-velero/velero/templates/crds.yaml":[""],"/tmp/velero-4bf57ed2-velero/velero/templates/deployment.yaml":[""],"/tmp/velero-4bf57ed2-velero/velero/templates/restic-daemonset.yaml":[""],"/tmp/velero-4bf57ed2-velero/velero/templates/secret.yaml":[""]}
{"/tmp/autoscaler-fb12fa7a-cluster-autoscaler/cluster-autoscaler/templates/deployment.yaml":[".spec.replicas: '2' != '0'"],"/tmp/autoscaler-fb12fa7a-cluster-autoscaler/cluster-autoscaler/templates/servicemonitor.yaml":["error: the server doesn't have a resource type \"ServiceMonitor\"\n"]}
{"/tmp/metrics-server-1960953a-metrics-server-certs/raw/templates/resources.yaml":["error: the server doesn't have a resource type \"Issuer\"\n","error: the server doesn't have a resource type \"Certificate\"\n"]}

$jq-s-r'map（@json）| join（“\n”）”

现在，您可以逐行处理它，而不必担心匹配大括号。

谢谢您的建议，上面的jq不适用于所有json负载。例如，对于下面的json负载，它给出了一个错误

 {
   "/tmp/ingress-dae7bd30-ingress-internet/nginx-ingress/templates/controller-deployment.yaml": [
     ".spec.replicas: '2' != '3'",
   ],
   "/tmp/ingress-dae7bd30-ingress-internet/nginx-ingress/templates/controller-metrics-service.yaml": [
     ".spec.clusterIP: '' != '10.3.24.53'"
   ],
   "/tmp/ingress-dae7bd30-ingress-internet/nginx-ingress/templates/controller-service.yaml": [
     ".spec.clusterIP: '' != '10.3.115.118'"
   ],
   "/tmp/ingress-dae7bd30-ingress-internet/nginx-ingress/templates/controller-stats-service.yaml": [
     ".spec.clusterIP: '' != '10.3.115.30'"
   ],
   "/tmp/ingress-dae7bd30-ingress-internet/nginx-ingress/templates/default-backend-deployment.yaml": [
   ]
 }
