.SH "DESCRIPTION"
.PP
This manual page documents briefly the
\fBsyslog\-summary\fR
command\.
.PP
\fBsyslog\-summary\fR
summarizes the contents of log files via the
\fBsyslog\fR(3)
service, by displaying each unique (except for the time) line once, and also the number of times such a line occurs in the input\. The lines are displayed in the order they occur in the input\.
.SH "OPTIONS"
.PP
\fB\-i \fR\fB\fIfilename\fR\fR, \fB\-\-ignore=\fR\fB\fIfilename\fR\fR
.RS 4
Read regular expressions from
\fIfilename\fR
and ignore lines in the logfiles that match them\.
.RE
.PP
\fB\-s \fR\fB\fIfilename\fR\fR, \fB\-\-state=\fR\fB\fIfilename\fR\fR
.RS 4
Read state information from
\fIfilename\fR\. The state contains information about the already reported parts of a log file, and prevents
\fBsyslog\-summary\fR
from reporting the same things many times\. This is useful when
\fBsyslog\-summary\fR
is run from
\fBcrontab\fR
every hour\. The file is created, if it doesn\'t exist already\.
.RE
.PP
\fB\-r\fR, \fB\-\-repeat\fR

Merge "last message repeated * times" lines with the repeated event\.
.RE
.PP
