NAME
dmesg - system diagnostic messages
SYNOPSIS
/etc/dmesg [ - ] [ -i ] [ core namelist ]
DESCRIPTION
Dmesg looks in a system buffer for recent console messages from the op-
erating system and reproduces them on the standard output. Under op-
tion dmesg produces only those messages printed by the system since the
last time was run. It is normally run periodically by cron(8) to pro-
duce the error log
Option -i prints messages produced since the last without changing any
records.
If core and namelist are specified, they are used in place of and

BUGS
Since the system error message buffer is small, not all error messages
are guaranteed to be logged.
Error messages generated immediately before a system crash may not be
logged.
