|
|
udevinfo queries the udev database for device information stored in the udev database. It can also query the properties of a device from its sysfs representation to help creating udev rules that match this device.

Query the database for specified type of device data. It needs the
|
|
\fB\-\-path\fR
|
|
or
|
|
\fB\-\-name\fR
|
|
to identify the specified device. Valid queries are:
|
|
\fBname\fR,
|

\fBsymlink\fR,
|
|
\fBpath\fR,
|

\fBenv\fR,
|
