azure aks – AKS : kubectl exec & kubectl log exits in between while the process is running in the container still

I am running the following kubectl exec & kubectl logs cmd at the same time on two different windows command prompt

kubectl exec ${pod} containername -n namespace -- bash -c "cd somebatch.ksh > /proc/1/fd/1 2>&1"

kubectl logs ${pod} containername -n namespace

both gets exited from the windows command prompt in between while the process is running in the container still.

If I run the kubectl logs cmd again, I could see the running logs

kubectl logs ${pod} containername -n namespace

What should I do to keep the kubectl exec & kubectl log commands running without exiting.
