-d dev-typeDESCRIPTION
The
list_devices utility lists the allocatable devices in the system
according to specified qualifications.
The
device and all device special files associated with the device are
listed. The device argument is optional and, if it is not present, all
relevant devices are listed. If
dev-class is present, devices belonging
to the specified
dev-class are listed. There is no default
dev-class.
OPTIONS
The following options are supported:
-l [
-c dev-class |
device]
Lists the pathnames of the device special
files associated with the
device that are
allocatable to the current process.
If
dev-class is specified, lists only the
files associated with all devices of the
specified device class.
If
device is specified, lists only the
files associated with the specified device.
-n [
-c dev-class |
device]
Lists the pathnames of the device special
files associated with the device that are
allocatable to the current process but are
not currently allocated.
If
dev-class is specified, lists only the
files associated with all devices of the
specified device class.
If
device is specified, lists only the
files associated with the specified device.
-s Silent. Suppresses any diagnostic output.
-u [
-c dev-class |
device]
Lists the pathnames of device special files
associated with the device that are
allocated to the owner of the current
process.
If
dev-class is specified, lists only the
files associated with all devices of the
specified device class.
If
device is specified, lists only the
files associated with the specified device.
-U uid Uses the user
ID uid instead of the real
user
ID of the current process when
performing the
list_devices operation. Only
a user with the
solaris.device.revoke authorization can use this option.
The following options are supported when the system is configured with
Trusted Extensions:
-a Lists attributes like authorizations, cleaning programs
and labels associated with a device.
The list is a single line of semicolon (
;) separated
key=value pairs for each device in the format:
device=
device-name;type=
device-type;\
auths=
auths;clean=
device-exec;\
device-attributes;\
files=
device-list where
device-attributes is the contents of the
reserved1 field of
device_allocate(5). The field is colon (
:)
separated.)
See
device_allocate(5) for a description of these
attributes and their format.
The
-a output has the following keys:
auths Specifies the list of authorizations. The value
is
auths is described in
device_allocate(5).
clean Specifies the device cleaning script. The value
is
device-exec as described in
device_allocate(5).
device Specifies the device name. The value is
device- name as described in
device_allocate(5).
files Specifies the device file paths. The value is
device-list as described in
device_maps(5).
type Specifies the device type. The value is
device- type as described in
device_allocate(5).
-d Displays the system-supplied default attributes for the
device types managed by device allocation. If
dev-type is
specified, it lists the default attributes for only that
device type.
-w This option can be used with
-a to list the current owner
of the device as the key value pair
owner=value.
value is
the
uid of the current owner of the device. If the device
is unallocated, value is
/FREE. If the device is in error
state, value is
/ERROR. This option also suppresses any
diagnostic output.
-z zonename When specified with the
-l option, lists only those non-
allocated devices whose label range includes the label of
the zonename, and of the allocated devices, only those
that are allocated at the same label as that of
zonename.
When specified with the
-n option, lists only those non-
allocated devices whose label range includes the label of
the
zonename.
When specified with the
-u option, lists only those
devices that are allocated at the same label as that of
zonename.
EXAMPLES
Example 1: Listing All Devices
The following example lists all devices available to the caller for
allocation:
% list_devices -l
device: audio type: audio \
files: /dev/audio /dev/audioctl /dev/sound/0 /dev/sound/0ctl
Example 2: Listing Attributes of All Devices
On a system configured with Trusted Extensions, the following example
lists attributes of all devices available to the caller for allocation:
% list_devices -al
device=audio1;type=audio;\
auths=solaris.device.allocate;\
clean=/etc/security/lib/audio_clean;\
minlabel=admin_low:maxlabel=admin_high;\
files=/dev/audio1 /dev/audio1ctl /dev/sound/1 /dev/sound/1ctl
Example 3: Listing Attributes Including the Device Owner
On a system configured with Trusted Extensions, the following example
lists attributes including the device owner of all devices allocated to
the user:
% list_devices -auw
device=audio2;type=audio;auths=solaris.device.allocate;\
clean=/etc/security/lib/audio_clean;\
minlabel=admin_low:maxlabel=admin_high:zone=public;\
owner=1234;\
files=/dev/audio2 /dev/audio2ctl /dev/sound/2 /dev/sound/2ctl
EXIT STATUS
The following exit values are returned:
0 Successful completion.
20 No entry for the specified device.
other value An error occurred.
