msgid

- generate message IDs

用法概要

/usr/sbin/msgid 

描述

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.
