SYNOPSIS
udevinfo [-q query-type] [-a ] [-p device-path] [-n node-name] [-r]
[-e] [-V] [-h]
DESCRIPTION
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.
OPTIONS
- -q Query the database for specified type of device data. It needs
- the -p or -n to identify the specified device. Valid queries are: name, symlink, path, env, all.
- -a Print all sysfs properties of the specified device that can be
- used in udev rules to match the specified device. It prints all
devices along the chain, up to the root of sysfs that can be
used in udev rules. - -p device-path
- The sysfs path of the device to query.
- -n node-name
- The name of the device node or a symlink to query
- -r The udev root directory: /dev. If used in conjunction with a
- name or symlink query, the query returns the absolute path.
- -e Export the content of the udev database.
- -h Print help text.
