.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
file contains a number of lines specifying a device together with a list
|
|
of devices with associated protections.
|
|
Comments start with a
|
|
.Ql #
|
|
and extend to the end of the line.
|
|
.Pp
|
|
Blank lines or lines with only a comment are ignored.
|
|
.Pp
|
|
All other lines consist of three fields delimited by
|
|
whitespace: a login device
|
|
.Pq Pa /dev/ttyv0 ,
|
|
an octal permission number (0600), and a colon
|
|
.Pq Ql \&:
|
|
delimited list of device patterns
|
|
.Pq Pa /dev/console , /dev/dsp* .
|
|
All device patterns are absolute paths.
|
|
.Pp
|
|
If the tty argument (relative path) matches a login device
|
|
name (absolute path), the permissions of the devices in the
|
|
colon-delimited list are set as specified in the second
|
|
field, and their ownership is changed to that of the UID
|
|
and GID arguments.
