Linux: How to determine which console I am using

Question

I use Ubuntu 12.04. I am logged-in to tty2, tty1 and tty7.

In my textbook I read that the whoami command allows me to determine which console I am using. But this command merely shows my login. As for the command who, it always lists tty2, tty1 and tty7. So, even the order of these consoles can't help me.

Could you help me how to determine the current console?

Answer 1

Use tty

$ tty
/dev/pts/1

Just remove the /dev/ and you've got it.

Answer 2

current:

$ tty | sed -e "s:/dev/::"
