tty(7)                                                     tty(7)



NAME
     tty - controls the 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
     appear  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
          Executable file
     /dev/tty*
          Device files
