DMESG(8) System Manager's Manual DMESG(8) NAME dmesg -- display the system message buffer SYNOPSIS dmesg [-s] [-M core] [-N system] DESCRIPTION dmesg displays the contents of the system message buffer. It is most commonly used to review system startup messages. On some systems the message buffer can survive reboot and be retained (in the hope of ex- posing information from a crash). The options are as follows: -M core Extract values associated with the name list from the specified core instead of the default /dev/kmem. -N system Extract the name list from the specified system instead of the default /bsd. -s Display the contents of the console message buffer instead. This can be used to review rc(8) system startup messages. This option is limited to the superuser. FILES /var/run/dmesg.boot copy of dmesg saved by rc(8) at boot time SEE ALSO syslogd(8) HISTORY The dmesg command appeared in Version 7 AT&T UNIX. OpenBSD 7.7 June 30, 2024 DMESG(8)
