msgid(1M) System Administration Commands msgid(1M)
NAME
msgid - generate message IDs
SYNOPSIS
/usr/sbin/msgid
DESCRIPTION
The msgid utility generates message IDs.
A message ID is a numeric identifier that, with a high probability, uniquely identifies a message. The probability of two distinct messages
having the same ID is about one in a million. 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.
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 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 ufs, to generate a message catalog.
example# strings /kernel/fs/ufs | msgid
