TTYS(5) BSD Programmer's Manual TTYS(5) NNAAMMEE ttttyyss - terminal initialization information DDEESSCCRRIIPPTTIIOONN The file ttttyyss contains information that is used by various routines to initialize and control the use of terminal special files. This informa- tion is read with the getttyent(3) library routines. There is one line in the ttttyyss file per special device file. Fields are separated by tabs and/or spaces. Fields comprised of more than one word should be enclosed in double quotes (``"''). Blank lines and comments may appear anywhere in the file; comments are delimited by hash marks (``#'') and new lines. Any unspecified fields will default to null. The first field is the name of the terminal special file as it is found in _/_d_e_v. The second field of the file is the command to execute for the line, usu- ally getty(8), which initializes and opens the line, setting the speed, waiting for a user name and executing the login(1) program. It can be, however, any desired command, for example the start up for a window sys- tem terminal emulator or some other daemon process, and can contain mul- tiple words if quoted. The third field is the type of terminal usually connected to that tty line, normally the one found in the termcap(5) data base file. The envi- ronment variable TERM is initialized with the value by either getty(8) or login(1). The remaining fields set flags in the _t_y___s_t_a_t_u_s entry (see getttyent(3)) or specify a window system process that init(8) will maintain for the terminal line. As flag values, the strings ``on'' and ``off'' specify that init should (should not) execute the command given in the second field, while ``se- cure'' (if ``on'' is also specified) allows users with a uid of 0 to lo- gin on this line. These flag fields should not be quoted. The string ``window='' may be followed by a quoted command string which init will execute _b_e_f_o_r_e starting the command specified by the second field.
