NAME
       tty - controlling terminal interface

DESCRIPTION
       The file	/dev/tty is, in	each process, a	synonym	for the	control	termi-
       nal 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 out-
       put, when typed output is desired and it	is tiresome to find  out  what
       terminal	is currently in	use.

FILES
       /dev/tty

       /dev/tty*
