devprop

- display device properties

形式

/usr/sbin/devprop [-n device-path] [-vq] [-{b|i|l|s}] [property[...]]

機能説明

The devprop command displays named device properties from the device tree.

If a device path is specified on the command line, devprop displays device properties for that device node.

The output formats, while Volatile, are patterned after those of prtconf(1M).

オプション

The following options are supported:

-b

The properties to be output are sequences of bytes (DI_PROP_TYPE_BYTES). -b, -i, -l, and -s are mutually exclusive of one another.

-i

The properties to be output are integers (DI_PROP_TYPE_INT).

-l

The properties to be output are 64–bit integers (DI_PROP_TYPE_INT64).

-s

The properties to be output are strings (DI_PROP_TYPE_STRING) (the default).

-n device-path

The path to a target device node for which properties are displayed. The default path is that of the root node (equivalent to specifying -n /).

-q

Specifies quoted output mode, in which string properties are output surrounded by double quotation marks (").

-v

Specifies verbose mode, in which the name of the property is output before its value.
