.Sh DESCRIPTION
|
|
The
|
|
.Nm lsdev
|
|
utility lists devices configured in the current system, in a
|
|
machine-dependent manner. The
|
|
.Fl t
|
|
flag can be used to restrict the listing to a specific
|
|
.Ar type
|
|
of device;
|
|
the types available vary from machine to machine. (Specifying an
|
|
invalid type will cause a list of valid types to be printed.) The
|
|
.Fl v
|
|
flag requests more verbose output. The
|
|
.Fl c
|
|
flag requests output in a format similar to the input of
|
|
.Xr config 8 .
|
|
The optional
|
|
.Ar class
|
|
argument requests information on a particular class of devices (e.g.,
|
|
.Dq Li wdc
|
|
or
|
|
.No Do Li ie Dc Ns ).
|
|
If no
|
|
.Ar unit
|
|
is specified, all units of the specified class will be listed.
|
|
.Pp
|
|
The
|
|
.Xr sysctl 3
|
|
mechanism is used to retrieve information from the kernel about which
|
|
devices are configured.
