       dmesg - collect system diagnostic messages to form error log

       looks  in  a system buffer for recently printed diagnostic messages and
       prints them on the standard output.  The messages are those printed  by
       the  system when unusual events occur (such as when system tables over‐
       flow or the system crashes).  If the argument  is  specified,  computes
       (incrementally)	the  new  messages  since the last time it was run and
       places these on the standard output.  This is typically used with  (see
       cron(1)) to produce the error log by running the command:

       every 10 minutes.

       The  arguments and allow substitution for the defaults and where should
       be a file containing the image of the kernel virtual  memory  saved  by
       the  savecrash(1M)  command and should be the corresponding kernel.  If
       the system is  booted  with  a  kernel  other  than  /stand/vmunix  say
       /stand/vmunix_new, must be passed this name, the command must be,

       The  system error message buffer is of small, finite size.  is run only
       every few minutes, so there is no guarantee  that  all  error  messages
       will be logged.
