.SH NAME
msgid \- generate message IDs
.SH SYNOPSIS
.LP
.nf
\fB/usr/sbin/msgid\fR 
.fi

.SH DESCRIPTION
.sp
.LP
The \fBmsgid\fR utility generates message \fBID\fRs.
.sp
.LP
A message \fBID\fR is a numeric identifier that uniquely identifies a message.
Although the probability of two distinct messages having the same \fBID\fR is
high, this can be greatly reduced with the appropriate priority or
facility.level designator (see \fBsyslogd\fR(1M)). Specifically, the message
\fBID\fR is a hash signature on the message's unexpanded format string,
generated by \fBSTRLOG_MAKE_MSGID()\fR as defined in \fB<sys/strlog.h>\fR\&.
.sp
.LP
\fBsyslogd\fR(1M) is a simple filter that takes strings as input and produces
those same strings, preceded by their message \fBID\fRs, as output. Every
message logged by \fBsyslogd\fR(1M) includes the message \fBID\fR. The message
\fBID\fR is intended to serve as a small, language-independent identifier.
.SH EXAMPLES
.LP
\fBExample 1 \fRUsing the msgid command to generate a message ID
.sp
.LP
The following example uses the \fBmsgid\fR command to generate a message
\fBID\fR for the \fBecho\fR command.

.LP
\fBExample 2 \fRUsing the msgid command to generate a message catalog

.LP
The following example uses the \fBmsgid\fR command to enumerate all of the
messages in the binary \fBufs\fR, to generate a message catalog.
