NAME
tty - Controlling terminal interface
DESCRIPTION
The /dev/tty file 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 output
is desired and name of the terminal currently in use is needed.
