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

     crash -- examine and debug system images

     crash [-M core] [-N kernel]

     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
     breakpoints, 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

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

     The crash command appeared in NetBSD 6.0.
