KEXTSTAT(8)

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.
