.Sh NAME
|
|
.Nm ttys
|
|
.Nd terminal initialization information
|
|
.Sh DESCRIPTION
|
|
The file
|
|
.Nm ttys
|
|
contains information that is used by various routines to initialize
|
|
and control the use of terminal special files.
|
|
This information is read with the
|
|
.Xr getttyent 3
|
|
library routines.
|
|
There is one line in the
|
|
.Nm ttys
|
|
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.
|
|
.Pp
|
|
The first field is the
|
|
name of the terminal special file as it is found in
|
|
.Pa /dev .
|
|
.Pp
|
|
The second field of the file is the command to execute for the line,
|
|
usually
|
|
.Xr getty 8 ,
|
|
which initializes and opens the line, setting the speed, waiting for
|
|
a user name and executing the
|
|
.Xr login 1
|
|
program.
|
|
It can be, however, any desired command, for example
|
|
the start up for a window system terminal emulator or some other
|
|
daemon process, and can contain multiple words if quoted.
|
|
.Pp
|
|
The third field is the type of terminal usually connected to that
|
|
tty line, normally the one found in the
|
|
.Xr termcap 5
|
|
data base file.
|
|
The environment variable
|
|
.Dv TERM
|
|
is initialized with the value by
|
|
either
|
|
.Xr getty 8
|
|
or
|
|
.Xr login 1 .
|
|
.Pp
|
|
The remaining fields set flags in the
|
|
.Fa ty_status
|
|
entry (see
|
|
.Xr getttyent 3 )
|
|
or specify a window system process that
|
|
.Xr init 8
|
|
will maintain for the terminal line.
|
|
.Pp
|
|
As flag values, the strings ``on'' and ``off'' specify that
|
|
.Xr init
|
|
should (should not) execute the command given in the second field,
|
|
while ``secure'' (if ``on'' is also specified) allows users with a
|
|
uid of 0 to login on
|
|
this line.
|
|
These flag fields should not be quoted.
|
|
.Pp
|
|
The string ``window='' may be followed by a quoted command
|
|
string which
|
|
.Xr init
|
|
will execute
|
|
.Em before
|
|
starting the command specified by the second field.
|
|
