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

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

NAME
     dmesg -- display the system message buffer

SYNOPSIS
     dmesg [-M core] [-N system]

DESCRIPTION
     dmesg displays the contents of the system message buffer.

     The options are as follows:

     -M      Extract values associated with the name list from the specified core instead of the
	     default ``/dev/mem''.

     -N      Extract the name list from the specified system instead of the default ``/netbsd''.

     The system message buffer is a circular buffer of a fixed size.  If the buffer has been
     filled, the first line of the dmesg output may not be complete.  The size of the message
     buffer is configurable at compile-time on most systems with the MSGBUFSIZE kernel option.
     Look for MSGBUFSIZE in options(4) for details.

FILES
     /var/run/dmesg.boot  copy of dmesg at the time of last boot.

SEE ALSO
     options(4), syslogd(8)

HISTORY
     The dmesg command appeared in 4.0BSD.
