ioreg

IOREG(8)						    BSD System Manager's Manual 						  IOREG(8)

NAME

     ioreg -- show I/O Kit registry

SYNOPSIS

     ioreg [-b] [[-c class] [-l] [-n name]] [-p plane] [-s] [-S] [-w width] [-x]

DESCRIPTION

     ioreg displays the I/O Kit registry.  The use of the -c, -l, or -n options cause ioreg to show the properties of objects matching the speci-
     fied criteria.  By default, ioreg does not show the properties of an object.

     The options are as follows:

     -b    Show the object name in bold.

     -c    Show the object properties only if the object is, or derives from, the specified class.

     -l    Show the object properties.

     -n    Show the object properties only if the object has the specified name.

     -p    Traverse the registry over the specified plane.  The default plane value is ``IOService''.  The other planes, such as ``IODeviceTree'',
	   can be found under the ``IORegistryPlanes'' property of the root object (ioreg -n Root).

     -s    Show the object state (busy state, retain count). This is the default.

     -S    Don't show the object state (busy state, retain count).

     -w    Clip the output to the specified line width.  The default width value is the current screen size.  A value of 0 specifies an unlimited
	   line width.

     -x    Print numeric property values in hexadecimal.
