+JSONPath regular expressions are not supported. If you want to match using regular expressions, you can use a tool such as `jq`.
+
+```shell
+# kubectl does not support regular expressions for JSONpath output
+# The following command does not work
+kubectl get pods -o jsonpath='{.items[?(@.metadata.name=~/^test$/)].metadata.name}'
 
+# The following command achieves the desired result
+kubectl get pods -o json | jq -r '.items[] | select(.metadata.name | test("test-")).spec.containers[].image'
+```
