DESCRIPTION

Note: dmesg is made obsolete by syslogd(1M) 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

/var/adm/msgbuf scratch file for memory of ‘−’ option
