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.
