User Commands list_devices(1)
NAME
list_devices - list allocatable devices
SYNOPSIS
list_devices [-s] [-U uid] [-z zonename] [-a [-w]]
-l | -n | -u [device] | [-l | -n | -u] -c dev-class
list_devices [-s] -d dev-type
DESCRIPTION
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, ifit 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 associ-
ated with the device that are allocatable to the current process.If dev-class is specified,
lists only the files associ-
ated 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 associ-
ated with the device that are allocatable to the current process but are not currently allocated.If dev-class is specified,
lists only the files associ-
ated with all devices of the specified device class.SunOS 5.11 Last change: 12 Aug 2010 1

If device is specified, lists only the files associated with the specified device.-s Silent. Suppresses any diag-
nostic 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 associ-
ated 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 thecurrent process when perform-
ing the list_devices opera-
tion. Only a user with thesolaris.device.revoke authori-
zation can use this option.The following options are supported when the system is con-
figured with Trusted Extensions:-a Lists attributes like authorizations, clean-
ing 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(4).
The field is colon (:) separated.)See device_allocate(4) for a description of
these attributes and their format.The -a output has the following keys:
auths Specifies the list of authoriza-
tions. The value is auths isdescribed in device_allocate(4).
clean Specifies the device cleaningscript. The value is device-exec as
described in device_allocate(4).
device Specifies the device name. Thevalue is device-name as described
in device_allocate(4).
files Specifies the device file paths.The value is device-list as
described in device_maps(4).
type Specifies the device type. Thevalue is device-type as described
in device_allocate(4).
-d Displays the system-supplied default attri-
butes for the device types managed by deviceallocation. 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 isunallocated, value is /FREE. If the device is
in error state, value is /ERROR. This option
also suppresses any diagnostic output.SunOS 5.11 Last change: 12 Aug 2010 3

-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

Controlling Access to Devices NOTES The functionality described in this man page is available only if Solaris Auditing has been enabled. The functionality described in this man page is availableonly if the device_allocate(1M) service is enabled.
On systems configured with Trusted Extensions, the func-
tionality is enabled by default. /etc/security/dev, mkdevalloc(1M), and mkdevmaps(1M) mightnot be supported in a future release of the Solaris Operat-
ing Environment.SunOS 5.11 Last change: 12 Aug 2010 6
