     crashinfo -- analyze a core dump of the operating system

     crashinfo [-d crashdir] [-n dumpnr] [-k kernel] [core]

     The crashinfo utility analyzes a core dump	saved by savecore(8).  It gen-
     erates 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	utili-
     ties 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.

     textdump(4), savecore(8)

     The crashinfo utility appeared in FreeBSD 6.4.
