NAME

6       udevinfo - query udev device information
7

SYNOPSIS

9       udevinfo [--query=query-type] [--path=devpath] [--name=node] [--root]
10                [--attribute-walk] [--export-db] [--version] [--help]

DESCRIPTION

13       udevinfo queries the udev database for device information stored in the
14       udev database. It can also query the properties of a device from its
15       sysfs representation to help creating udev rules that match this
16       device.
17

OPTIONS

19       --query=type
20           Query the database for specified type of device data. It needs the
21           --path or --name to identify the specified device. Valid queries
22           are: name, symlink, path, env, all.
23
24       --path=devpath
25           The devpath of the device to query.
26
27       --name=node
28           The name of the device node or a symlink to query
29
30       --root
31           The udev root directory: /dev. If used in conjunction with a name
32           or symlink query, the query returns the absolute path including the
33           root directory.
34
35       --attribute-walk
36           Print all sysfs properties of the specified device that can be used
37           in udev rules to match the specified device. It prints all devices
38           along the chain, up to the root of sysfs that can be used in udev
39           rules.
40
41       --export-db
42           Export the content of the udev database.
43
44       --version
45           Print version.
46
47       --help
48           Print help text.
