watch

I have a android emulator running on port 5554. I want to continuously watch the netstat output concerning emulator stuff.

right now I have to manually execute this command every time

sudo netstat -plant | grep emulator

I thought doing something like this would repeat above command automatically every 2 sec.

watch sudo netstat -plant | grep emulator

but instead it hangs the terminal. How to achieve such functionality ? Thanks
