dmesg

DMESG(1)						      General Commands Manual							  DMESG(1)

NAME

       dmesg - print or control the kernel ring buffer

SYNOPSIS

       dmesg [-c] [-r] [-n level] [-s bufsize]

DESCRIPTION

       dmesg is used to examine or control the kernel ring buffer.

       The program helps users to print out their bootup messages.  Instead of copying the messages by hand, the user need only:
	      dmesg > boot.messages
       and mail the boot.messages file to whoever can debug their problem.

OPTIONS

       -c     Clear the ring buffer contents after printing.

       -r     Print the raw message buffer, i.e., don't strip the log level prefixes.

       -s bufsize
	      Use a buffer of size bufsize to query the kernel ring buffer.  This is 16392 by default.	(The default kernel syslog buffer size was
	      4096 at first, 8192 since 1.3.54, 16384 since 2.1.113.)  If you have set the kernel buffer to be larger than the default	then  this
	      option can be used to view the entire buffer.

       -n level
	      Set  the level at which logging of messages is done to the console.  For example, -n 1 prevents all messages, except panic messages,
	      from appearing on the console.  All levels of messages are still written to /proc/kmsg, so syslogd(8) can still be used  to  control
	      exactly where kernel messages appear.  When the -n option is used, dmesg will not print or clear the kernel ring buffer.

	      When both options are used, only the last option on the command line will have an effect.

AVAILABILITY

       The dmesg command is part of the util-linux-ng package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/.
