For example, you can display the nvidia-smi tool in a new terminal window so you can monitor the GPU power draw. Either command will spawn the new terminal window and the original shell will continue running uninterrupted.

$ xterm -wf -T "[nvidia-smi] GPU power consumption" -e "watch -n 1 nvidia-smi" &

or

$ gnome-terminal --command="watch -n 1 nvidia-smi"
