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*
