tty(7)                                                     tty(7)



     NAME
          tty - controlling terminal interface

     DESCRIPTION
          The file /dev/tty is, in each process, the control  terminal
          associated with the process group of that process.  Programs
          or shell sequences use it to ensure that their messages  ap-
          pear  on  the  terminal, no matter how output is redirected.
          Also, programs that demand an output file name  will  accept
          /dev/tty,  so  you don't have to find out what terminal they
          are using.

     FILES
          /dev/tty
          /dev/tty*
