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.
