       NAME
             tty - get the name of the terminal

       SYNOPSIS
             tty [-l] [-s]

       DESCRIPTION
             tty prints the pathname of the user's terminal.  It accepts
             the following options:

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

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

       NOTICES
             Application authors should avoid use of the -s option, since

             its place.
