KDUMPD(8) BSD System Manager's Manual KDUMPD(8)NAME
kdumpd -- Mac OS X remote kernel core dump server
SYNOPSIS
/usr/libexec/kdumpd [directory]
DESCRIPTION
Kdumpd is a server which receives kernel states in the form of a core dump from a remote Mac OS X machine. The kdumpd server operates on UDP
port 1069, although this may be configurable in the future. The server should be started by inetd(8).
The server should have the user ID with the lowest possible privilege, usually the user "nobody". The directory specified as a server pro-
gram argument in /etc/inetd.conf directs the server to store kernel cores in that directory and nowhere else. The server returns an EEXIST
error to the remote kernel if it receives a request for an existing file - i.e. only new files can be created. The server also disallows
path specifications in the incoming file name.
HISTORY
The kdumpd command is based on Berkeley tftpd(8) by way of FreeBSD, with several modifications.

CRASHINFO(8) BSD System Manager's Manual CRASHINFO(8)NAME
crashinfo -- analyze a core dump of the operating system
SYNOPSIS
crashinfo [-d crashdir] [-n dumpnr] [-k kernel] [core]
DESCRIPTION
The crashinfo utility analyzes a core dump saved by savecore(8). It generates a text file containing the analysis in the same directory as
the core dump. For a given core dump file named vmcore.XX the generated text file will be named core.txt.XX.
By default, crashinfo analyzes the most recent core dump in the core dump directory. A specific core dump may be specified via either the
core or dumpnr arguments. Once crashinfo has located a core dump, it analyzes the core dump to determine the exact version of the kernel
that generated the core. It then looks for a matching kernel file under each of the subdirectories in /boot. The location of the kernel
file can also be explicitly provided via the kernel argument.
Once crashinfo has located a core dump and kernel, it uses several utilities to analyze the core including dmesg(8), fstat(1), iostat(8),
ipcs(1), kgdb(1), netstat(1), nfsstat(1), ps(1), pstat(8), and vmstat(8).
The options are as follows:
-d crashdir
Specify an alternate core dump directory. The default crash dump directory is /var/crash.
-n dumpnr
Use the core dump saved in vmcore.dumpnr instead of the latest core in the core dump directory.
-k kernel
Specify an explicit kernel file.

The crashinfo utility appeared in FreeBSD 6.4.

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.

Greetings,
I'm trying to delete a file with a weird name from within Terminal on a Mac.
It's a very old file (1992) with null characters in the name: ââWord FinderÂŽ Plusâ˘.

Hi all...
Well guys and gals, I jumped in at the deep end and found things that PERL cannot do by default.
Many tricky terminal escape codes are not catered for so I had to create workarounds.
One thing I searched for was this:

So this gave me the inspiration to attempt a GOTO function for 'dash', (bash and ksh too).
