KEXTSTAT(8)

NAME
kextstat - display status of loaded kernel extensions (kexts)

SYNOPSIS
kextstat [-a] [-h] [-k] [-l] [-b identifier] ...

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

Index
    The load index of the kext (used to track linkage references). Gaps in the list indicate kexts that have been unloaded.

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

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

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

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

Architecture (if the -a option is used)
    The architecture of the kext.

Name
    The CFBundleIdentifier of the kext.

(Version)
    The CFBundleVersion of the kext.

<Linked Against>
    The index numbers of all other kexts that this kext has a reference to.

OPTIONS
These options are available:

-a, -arch
    Print the architecture of the kext.

-b identifier, -bundle-id identifier
    Display the status of only the kext with the given bundle identifier. This option trumps the -no-kernel option; if both are given and a kernel component is specified, its information is shown.

-h, -help
    Print a help message describing each option flag and exit with a success result, regardless of any other options on the command line.

-k, -no-kernel
    Don't show information for built-in components of the kernel.

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

-s, -sort
    Sort the list by load address.

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