devprop

- display device properties

Synopsis

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

Description

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 boolean property prints out true (with the -e option) if it exists; it is otherwise false. Byte, int, and int_64 property values display in hex format if one specifies type by means of options -b, -i, or -l; otherwise these values display in decimal format. Array property values are separated by a user-defined char.

Options

The options below are supported. Note that the -e, -b, -i, -l, and -s options are mutually exclusive.

-b

The properties to be output are sequences of bytes (DI_PROP_TYPE_BYTES).

-c separator

Specifies the separator in an array property. Use double quotation marks (" ") to specify a space. The default separator is the plus sign (+) for the string type and period (.) for others.

-e

The properties to be output are booleans (DI_PROP_TYPE_BOOLEAN).

-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).

-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 (").

-s

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

-v

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

Operands

The following operand is supported:

property...

Name of the property to be displayed.

Exit Status

0

No error occurred.

non-zero

An error occurred.
