MKEXTUNPACK(8)						    BSD System Manager's Manual 					    MKEXTUNPACK(8)

NAME
mkextunpack -- extracts the contents of a multikext (mkext) archive SYNOPSIS
mkextunpack [-v] [-d output_directory] mkext_file DESCRIPTION
The mkextunpack program list the contents of a multikext file, mkext_file, or unarchives the contents into output_directory (which must exist). The -v option causes mkextunpack to print the name if each kext as it finds them. DIAGNOSTICS
mkextunpack exits with a zero status upon success. Upon failure, it prints an error message and exits with a nonzero status. SEE ALSO
mkextcache(8) BUGS
The mkext file format doesn't record the original filenames of the kexts, so mkextunpack has to guess at what they are. It does this by using the value of the CFBundleExecutable property of the kext's info dictionary. (Project Builder sets this to the base name of the kext bundle by default, but the developer can change it.) If that property doesn't exist, the last component of the CFBundleIdentifier is used. Duplicates have an incrementing index appended to the name. Kexts that have no executable or CFBundleIdentifier are named ``NameUnknown-n.kext'', where n is a number. Darwin March 29, 2002 Darwin

KEXTSTAT(8)						    BSD System Manager's Manual 					       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. SEE ALSO

Shopt -s histappend

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file. # When the shell exits, append to the history file instead of overwriting it shopt -s histappend (3 Replies)
