NAME


msgid - generate message IDs

SYNOPSIS


/usr/sbin/msgid


DESCRIPTION


The msgid utility generates message IDs.


A message ID is a numeric identifier that uniquely identifies a message.
Although the probability of two distinct messages having the same ID is
high, this can be greatly reduced with the appropriate priority or
facility.level designator (see syslogd(1M)). Specifically, the message ID
is a hash signature on the message's unexpanded format string, generated
by STRLOG_MAKE_MSGID() as defined in <sys/strlog.h>.


syslogd(1M) is a simple filter that takes strings as input and produces
those same strings, preceded by their message IDs, as output. Every
message logged by syslogd(1M) includes the message ID. The message ID is
intended to serve as a small, language-independent identifier.
