TTY(1) BSD General Commands Manual TTY(1)
tty -- return user's terminal name
The tty utility writes the name of the terminal attached to standard input to standard out-
put. The name that is written is the string returned by ttyname(3). If the standard input
is not a terminal, the message ``not a tty'' is written. The options are as follows:
-s Don't write the terminal name; only the exit status is affected when this option is
specified. The -s option is deprecated in favor of the ``test -t 0'' command.
The tty utility exits 0 if the standard input is a terminal, 1 if the standard input is not
a terminal, and >1 if an error occurs.
The tty utility is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible.
A tty command appeared in Version 1 AT&T UNIX.
