     dmesg -- display the system message buffer

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

     The dmesg utility displays the contents of the system message buffer.  If the -M option is
     not specified, the buffer is read from the currently running kernel via the sysctl(3) inter-
     face.  Otherwise, the buffer is read from the specified core file, using the name list from
     the specified kernel image (or from the default image).

     The options are as follows:

     -a      Show all data in the message buffer.  This includes any syslog records and
	     /dev/console output.

     -c      Clear the kernel buffer after printing.

     -M      Extract values associated with the name list from the specified core.

     -N      If -M is also specified, extract the name list from the specified system instead of
	     the default, which is the kernel image the system has booted from.

     /var/run/dmesg.boot  usually a snapshot of the buffer contents taken soon after file systems
			  are mounted at startup time

     sysctl(3), syslogd(8)

     The dmesg utility appeared in 4.0BSD.
