TTY(7-SysV)         RISC/os Reference Manual          TTY(7-SysV)



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*

SEE ALSO
     console(7).
