.SH DESCRIPTION
.I Dmesg
looks in a system buffer
for recent console messages from the operating system
and reproduces them on the standard output.
Under option
.LR - ,
.I dmesg
produces only those messages printed by the system
since the last time
.L dmesg\ -
was run.
It is normally run periodically by
.IR cron (8)
to produce the error log
.FR /usr/adm/messages .
.PP
Option
.B -i
prints messages produced since the last
.L dmesg\ -
without changing any records.
.PP
If
.I core
and
.I namelist
are specified,
they are used in place of
.F /dev/kmem
and
.FR /unix .

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