NAME
       tty - controlling terminal interface

DESCRIPTION
       The  file /dev/tty is, in each process, a synonym for the control terminal associated with the process group of that process, if any. It is
       useful for programs or shell sequences that wish to be sure of writing messages on the terminal no matter how output has  been  redirected.
       It  can	also  be  used for programs that demand the name of a file for output, when typed output is desired and it is tiresome to find out
       what terminal is currently in use.

FILES
       /dev/tty

       /dev/tty*
