NAME

devattr - lists device attributes

SYNOPSIS

devattr [-v] device [attribute [...]]

DESCRIPTION

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 are
shown and they are displayed in  command  line  order.   The
options and arguments for this command are:
-v           Specifies verbose format.  Attribute values are
             displayed in an attribute=value format.
device       Defines the device whose attributes  should  be
             displayed.   Can  be the pathname of the device
             or the device alias.
attribute    Defines which attribute, or attributes,  should
             be  shown.   Default  is to show all attributes
             for a device.  See the putdev(1M)  manual  page
             for  a  complete  listing  and  description  of
             available attributes.
