TTY(1)			FreeBSD	General	Commands Manual			TTY(1)

NAME
     tty -- return user's terminal name

SYNOPSIS
     tty [-s]

DESCRIPTION
     The tty utility writes the	name of	the terminal attached to standard
     input to standard output.	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	     Do	not 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.

SEE ALSO
     test(1), ttyname(3)

STANDARDS
     The tty utility is	expected to be IEEE Std	1003.2 (``POSIX.2'') compati-
     ble.

HISTORY
     A tty command appeared in Version 1 AT&T UNIX.
