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 mes‐
       sage. 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(8)). Specifically,  the  mes‐
       sage  ID is a hash signature on the message's unexpanded format string,
       generated by STRLOG_MAKE_MSGID() as defined in <sys/strlog.h>.


       msgid 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(8)  includes  the  message  ID.  The  message  ID  is
       intended to serve as a small, language-independent identifier.

EXAMPLES
       Example 1 Using the msgid command to generate a message ID



       The  following  example uses the msgid command to generate a message ID
       for the echo command.


         example# echo hello | msgid
         205790 hello
         example#


       Example 2 Using the msgid command to Generate a Message Catalog



       The following example uses the msgid command to enumerate  all  of  the
       messages  in  the  binary zfs, on an x86 machine, to generate a message
       catalog.


         example# strings /kernel/fs/amd64/zfs | msgid
         ...
