tty(1)             UNIX System V(User Environment Utilities)             tty(1)


NAME
      tty - get the name of the terminal

SYNOPSIS
      tty [ -l ] [ -s ]

DESCRIPTION
      tty prints the path name of the user's terminal.

      -l    prints the synchronous line number to which the user's terminal is
            connected, if it is on an active synchronous line.

      -s    inhibits printing of the terminal path name, allowing one to test
            just the exit code.

                                     EXIT CODES
                       2   if invalid options were specified,
                       0   if standard input is a terminal,
                       1   otherwise.

DIAGNOSTICS
      ``not on an active synchronous line'' if the standard input is not a
      synchronous terminal and -l is specified.
      ``not a tty'' if the standard input is not a terminal and -s is not
      specified.
