NAME
       udevinfo - retrieve information from udev

SYNOPSIS
       udevinfo [-q query_type -p sysfs_path] [-drVh]

DESCRIPTION
       udevinfo allows users to query the udev database for information on any
       device currently present on the system.  It also provides a way to
       query any device in the sysfs tree to help creating udev rules.

OPTIONS
       -V     Print the version information.

       -r     Print the udev_root directory. When used in conjunction with a
              query for the node name, the udev_root will be prepended.

       -q query_type
              Query the database for specified value of a created device node
              or network interface.  Needs -p or -n specified.
              Valid types are: name, symlink, mode ,owner , group , path or
              all.

       -p sysfs_path
              Specify the sysfs path of the device to query.

       -n name
              Specify the name of the node, the symlink or the network
              interface for the device to query. Partition names generated
              with the NAME{all_partitons} option can not be queried, the main
              device must be used instead.

       -a     Print all SYSFS{filename} attributes along the device chain.
              Useful for finding unique attributes to compose a rule.  Needs
              -p specified.

       -d     Dump the whole database.

       -h     Print help text.
