Usage

Attempts PCRE2 matches against values (and optionally keys) and returns match location in jsonpath (optionally returns value found at jsonpath). Can optionally accept standard input using the filename -.

Example:

$ kubectl get pvc pmm-client-backups -o json | jp - "ReadWrite"
.metadata.annotations.kubectl.kubernetes.io/last-applied-configuration
.spec.accessModes[0]
.status.accessModes[0]

$ curl -s https://api.github.com/repos/kubernetes/kubernetes/issues | jp - "[cC]layton"
