Pass command-line result as an argument to next command Trying to insert output from this: kubectl get pods | grep -Eo '^[^ ]+' | grep portal Into this: kubectl exec -it <here> portal bash Tried: kubectl exec -it `kubectl get pods | grep -Eo '^[^ ]+' | grep portal ` portal bash But no luck.

kubectl exec -it "$(kubectl get pods | grep -Eo '^[^ ]+' | grep portal)" bash


Or, even more:


kubectl exec -c portal-container -it "$(kubectl get pods | grep -Eo '^[^ ]+' | grep portal)" bash
