Here my shell script in my host.

#!/bin/bash
loginCommend="kubectl -n my-namespace exec -it my-demo-app-58df8dc87-568gb /bin/bash"
eval "$loginCommend"
ls -la

My shell script is stop after eval "$loginCommend".

Which mean shell script is stop after changing/ssh to another host, I think. I would like to do continuous running ls -la.
