tty(1)                   USER COMMANDS                     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 synchro-
          nous 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.
