NAME
     kextstat -- display status of dynamically loaded kernel extensions

SYNOPSIS
     kextstat [-b kext_bundle_id] [-k] [-l]

DESCRIPTION
     The kextstat utility displays the status of any kernel extensions currently loaded in the kernel.	The following information is shown for
     each loaded kernel extension:

     Index     The load index of the kernel extension (used to track references).  Gaps in the list indicate kernel extensions that have been
	       unloaded.

     Refs      The number of references to this extension by others.  If nonzero, the extension cannot be unloaded.

     Address   The address in kernel space where the extension has been loaded.

     Size      The number of bytes of kernel memory that the extension occupies.  If this is zero, the extension is actually a built-in part of
	       the kernel that has a record as an extension for resolving dependencies among extensions.

     Wired     The number of wired bytes of kernel memory that the extension occupies.

     Name      The CFBundleIdentifier of the kernel extension.

     (Version)
	       The CFBundleVersion of the kernel extension.

     <Linked Against>
	       The index numbers of all other kernel extensions that this extension has a reference to.

     The following options are available:

     -b kext_bundle_id
	       Display the status of only the kernel extension with the given bundle identifier.  This option trumps the -k option; if both are
	       given and a kernel component is specified, its information is shown.

     -k        Don't show information for built-in components of the kernel.

     -l        Print the list of loaded kexts only and omit the header (useful for running output through text-analysis tools).

DIAGNOSTICS
     The kextstat utility exits with a status of 0 on success and with a nonzero status if an error occurs.
