.TH LOGGER 1 "Feb 1, 1995"
.SH NAME
logger \- add entries to the system log
.SH SYNOPSIS
.LP
.nf
\fBlogger\fR [\fB-i\fR] [\fB-f\fR \fIfile\fR] [\fB-p\fR \fIpriority\fR] [\fB-t\fR \fItag\fR] [\fImessage\fR] ...
.fi
.SH DESCRIPTION
.sp
.LP
The \fBlogger\fR command provides a method for adding one-line entries to the
system log file from the command line. One or more \fImessage\fR arguments can
be given on the command line, in which case each is logged immediately. If this
is unspecified, either the file indicated with \fB-f\fR or the standard input
is added to the log. Otherwise, a \fIfile\fR can be specified, in which case
each line in the file is logged. If neither is specified, \fBlogger\fR reads
and logs messages on a line-by-line basis from the standard input.
.SH OPTIONS
.sp
.LP
The following options are supported:
.sp
.ne 2
.na
\fB\fB-f\fR\fIfile\fR\fR
.ad
.RS 14n
Uses the contents of \fIfile\fR as the message to log.
.RE
.sp
.ne 2
.na
\fB\fB-i\fR\fR
.ad
.RS 14n
Logs the process \fBID\fR of the \fBlogger\fR process with each line.
.RE
.sp
.ne 2
.na
\fB\fB-p\fR\fIpriority\fR\fR
.ad
.RS 14n
Enters the message with the specified \fIpriority\fR. The message priority can
be specified numerically, or as a \fIfacility\fR\fB\&.\fR\fIlevel\fR pair. For
example, `\fB\fR\fB-p\fR\fB local3.info\fR' assigns the message priority to the
\fBinfo\fR level in the \fBlocal3\fR facility. The default priority is
\fBuser.notice\fR.
.RE
.sp
.ne 2
.na
\fB\fB-t\fR\fItag\fR\fR
.ad
.RS 14n
Marks each line added to the log with the specified \fItag\fR.
.RE
.SH OPERANDS
.sp
.LP
The following operand is supported:
.sp
.ne 2
.na
\fB\fImessage\fR\fR
.ad
.RS 11n
One of the string arguments whose contents are concatenated together, in the
order specified, separated by single space characters.
.RE
.SH EXAMPLES
.LP
\fBExample 1 \fRExamples of the logger command
.sp
.LP
The following example:
.sp
.in +2
.nf
example% \fBlogger System rebooted\fR
.fi
.in -2
.sp
.sp
.LP
logs the message `\fBSystem rebooted\fR' to the default priority level
\fBnotice\fR to be treated by \fBsyslogd\fR as are other messages to the
facility \fBuser\fR.
.sp
.LP
The next example:
.sp
.in +2
.nf
example% \fBlogger -p local0.notice -t HOSTIDM -f /dev/idmc\fR
.fi
.in -2
.sp
.sp
.LP
reads from the file \fB/dev/idmc\fR and logs each line in that file as a
message with the tag `\fBHOSTIDM\fR' at priority level \fBnotice\fR to be
treated by \fBsyslogd\fR as are other messages to the facility \fBlocal0\fR.
.SH ENVIRONMENT VARIABLES
.sp
.LP
See \fBenviron\fR(5) for descriptions of the following environment variables
that affect the execution of \fBlogger\fR: \fBLANG\fR, \fBLC_ALL\fR,
\fBLC_CTYPE\fR, \fBLC_MESSAGES\fR, and \fBNLSPATH\fR.
.SH EXIT STATUS
.sp
.LP
The following exit values are returned:
.sp
.ne 2
.na
\fB\fB0\fR\fR
.ad
.RS 6n
Successful completion.
