CRASH(8)                NetBSD 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 architecture 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) manual page for more information.

     Operations and facilities that require a running system, such as break-
     points, are not supported 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)
