You can't cat a local file over. One way is to store the file in a BASH variable first before sending it over

lists=$(cat /lists); kubectl exec Pod1 "echo $lists >> HELLO"

But this isn't a great way either. Are you attempting to debug the app or to automate some process by writing to a file this way? If it's the latter, may I suggest using a ConfigMap instead?
