Answer 2

Разобрался сам.Вы можете использовать параметр --formatter json Не удалось найти его в документации rabbitmq !

sudo rabbitmqctl cluster_status --formatter json

sudo rabbitmqctl cluster_status --formatter json | jq .running_nodes

Чтобы проанализировать это и использовать его в сценарии bash:

running_nodes=($(egrep -o '[a-z0-9@-]+' <<< $(sudo rabbitmqctl cluster_status --formatter json | jq .running_nodes)))
