NetBSD 6.1.5 - man page for crash (netbsd section 8)

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

NAME
     crash -- examine and debug system images

SYNOPSIS
     crash [-M core] [-N kernel]

DESCRIPTION
     The crash command is used to examine and debug system images.

     If run without any arguments, crash operates on the running system.

     The options are as follows:

     -M core	   Operate on the specified crash dump instead of the default /dev/mem.  Crash
		   dumps should be from the same version of the system and same machine architec-
		   ture as the running version of crash, and must be uncompressed.

     -N kernel	   Extract the name list from the specified kernel instead of the default
		   /dev/ksyms.

     The command syntax used by crash is the same as the in-kernel debugger.  See the ddb(4) man-
     ual page for more information.

     Operations and facilities that require a running system, such as breakpoints, are not sup-
     ported by crash.

     crash does not provide pagination.  However, by using the pipe symbol, output may be sent to
     commands available from the shell.  For example:

	 crash> ps | more
	 crash> ps | grep ioflush

SEE ALSO
     ps(1), vmstat(1), ddb(4), pstat(8)

HISTORY
     The crash command appeared in NetBSD 6.0.
