NAME
       dmesg - collect system diagnostic messages to form error log

SYNOPSIS
       /sbin/dmesg [ - ]

DESCRIPTION
       N.B.: Dmesg is obsoleted by syslogd(8) for maintenance of the system error log.

       Dmesg  looks  in  a  system buffer for recently printed diagnostic messages and prints them on the standard output.  The messages are those
       printed or logged by the system when errors occur.  If the - flag is given, then dmesg computes (incrementally) the new messages since  the
       last time it was run and places these on the standard output.

FILES
       /usr/adm/msgbuf	   scratch file for memory of - option
