NAME
dmesg - system diagnostic messages
SYNOPSIS
/etc/dmesg [ - ] [ -i ] [ core namelist ]
DESCRIPTION
Dmesg looks in a system buffer for recent kernel diagnostic messages
and reproduces them on the standard output. If the - flag is given,
dmesg produces only those messages printed by the system since the last
time `dmesg -' was run. This can be used with cron(8) to produce the
error log /usr/adm/messages by running the command
/etc/dmesg - >> /usr/adm/messages
periodically.
If -i is given, messages produced since the last dmesg - are printed;
the memory of which messages have been recorded is not changed.
If core and namelist are specified, they are used in place of /dev/kmem
and /unix.
FILES
/usr/adm/messages error log
/usr/adm/msgbuf scratch file for memory of - option
BUGS
Since the system error message buffer is of small finite size, not all
error messages are guaranteed to be logged.
Error diagnostics generated immediately before a system crash cannot be
logged.
