IOREG(8) BSD System Manager's Manual IOREG(8)NAMEioreg — show I/O Kit registry
SYNOPSISioreg [-b] [[-c class] [-l] [-n name]] [-p plane] [-s] [-S] [-w width]
[-x]
DESCRIPTIONioreg 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 ``IODevice‐
Tree'', 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 unlim‐
ited line width.
-x Print numeric property values in hexadecimal.
