dmesg(ADM)
dmesg --
display the system messages on the console
Syntax
dmesg [ 
]
Description
The dmesg
command displays the most recent system message.
If the option (dash) is specified, it displays only
those messages generated since the
last time the dmesg command was used.
dmesg can be invoked periodically by placing
instructions in the file /usr/lib/crontab.
It can also be invoked automatically by
the /etc/rc2 scripts whenever the system is booted.
See ``Limitations'', below.
Limitations
dmesg is included in this release for backwards compatibility only.
The device /dev/error provides a more flexible means of logging
error messages, and is recommended over dmesg. See
error(HW)
for more information.
dmesg logs all error messages it prints in
/usr/adm/messages. If dmesg is invoked automatically,
the messages file continues to grow and can become very large.
The system administrator should occasionally erase its contents.
