DMESG(8) DMESG(8) 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.
