kextstat(8)

display status of loaded kernel extensions (kexts)

NAME

kextstat – display status of loaded kernel extensions (kexts)

SYNOPSIS

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

DEPRECATED

The kextstat utility has been deprecated. Please use the kmutil(8) equivalent: kmutil showloaded.

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.
