devattr displays the values for a device's attributes. The display can be presented in two formats. Used without the -v option, only the attribute values are shown. Used with the -v option, the attributes are shown in an attribute=value format. When no attributes are given on the command line, all attributes for the specified device are displayed in alphabetical order by attribute name. If attributes are given on the command line, only those attributes are shown, displayed in command line order.
The following options are supported:
