The kextstat utility has been deprecated.
Please use the kmutil(8) equivalent: kmutil
showloaded.
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.
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.
The kextstat utility exits with a status
of 0 on success and with a nonzero status if an error occurs.
