tty(7)                                                               tty(7)


   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*
