The tty command displays the name of your terminal.
For example, at the prompt, type:
tty
Press Enter.
The system displays information similar to the following:
/dev/tty06
In this example, tty06 is the name of the terminal, and /dev/tty06 is the device file that contains the interface to this terminal.
See the tty command in the AIX 5L Version 5.1 Commands Reference for the exact syntax.
