   tty(1)                 (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.
