.TH "lwatch" "1"
.SH "NAME"
\fBlwatch\fR \(em syntax highlighting for syslog/syslog-ng file
.SH "SYNOPSIS"
.PP
\fBlwatch\fR [\-C \fIfilename\fR] [\-\-config \fIfilename\fR] [\-i \fIfilename\fR] [\-\-input \fIfilename\fR] [\-o \fIfilename\fR] [\-\-output \fIfilename\fR] [\-sdOhv] [\-\-show-unparsed] [\-\-daemon] [\-\-omit-rc] [\-\-help]
.SH "DESCRIPTION"
.PP
Lwatch is a log colorizer. It reads syslog/syslog-ng data
from named fifo or from stdin and displays colored logs into
stdout.
.PP
Lwatch is highly user-customizable. It reads configuration
data from the file @CONFDIR@/lwatch.conf or (if given) from the file provided with option
\fB-C\fP
.PP
The way it works is simple. It reads a line from input (build-in default is @INPUTFILE@), splits it
into four parts: date, hostname, service name (with PID, if available)
and real message. Each part has its own default color. You can redefine
them in configuration file. Default colors as the same as in loco(1)
[see: http://www.zjuul.net/~jules/loco/]. But lwatch is not only a static log
colorizer. It is something more. It can colorize your logs any way
you wish. You are able to set a new color for any part (date, host,
service, message) using regexp based patterns.
.SH "COMMAND LINE OPTIONS"
.PP
Lwatch accepts some command line options. Command line options have precedence over values from configuration file.
.IP "\fB-C \fIfilename\fR\fP" 10
.IP "\fB\-\-config \fIfilename\fR\fP" 10
read config from filename instead of @CONFDIR@/lwatch.conf
.IP "\fB-i \fIfilename\fR\fP" 10
.IP "\fB\-\-input \fIfilename\fR\fP" 10
read data from named fifo filename instead of @INPUTFILE@
.IP "\fB-o \fIfilename\fR\fP" 10
.IP "\fB\-\-output \fIfilename\fR\fP" 10
write colored logs to filename instead stdout
.IP "\fB-s\fP" 10
.IP "\fB\-\-show-unparsed\fP" 10
show unparsed lines like `last message repeated 5 times' or `\-\-- MARK \-\--'
.IP "\fB-d\fP" 10
.IP "\fB\-\-daemon\fP" 10
run as daemon, detach from control terminal, move to background
.IP "\fB-O\fP" 10
.IP "\fB\-\-omit-rc\fP" 10
do not read values from config file
.IP "\fB-h\fP" 10
.IP "\fB\-\-help\fP" 10
show help about runtime option
.IP "\fB-v\fP" 10
.IP "\fB\-\-version\fP" 10
show version and copyright notices
.SH "RUNNING"
.PP
Preferred way to run lwatch is to read syslog messages from named fifo or from standard input.
.PP
If you use syslog you really want to read messages from named fifo.
To do it, put a line:
.PP
.nf
*.* |@INPUTFILE@
.fi
in your syslog.conf. Create appropriate fifo and restart syslog, then run
lwatch. You can also run lwatch before starting syslog.
If you don't know how to create named fifo see mknod(1) for details.
.PP
Remember:
.IP " \(bu" 6
fifo must exist
.IP " \(bu" 6
proper name must be put in @CONFDIR@/lwatch.conf or given with \-i command line option
.PP
In syslog-ng you can run lwatch directly from syslog, i.e.:
.PP
.nf
log { source(src); destination(console_all);};
destination console_all {program("@BINDIR@/lwatch \-i- \-o/dev/tty11"); };
.fi
.PP
Lwatch does not support reading from regular files. If you really need this functionality use following command:
.PP
.nf
tail \-f /path/to/filename | @BINDIR@/lwatch \-i-
.fi
It could be subject to change in the future.

.SH "NOTE FROM AUTHOR"
.PP
I have written this tool for my own needs because perl tools, however flexible, eated a lot of memory and CPU.
I have found it useful and I share it with the Open Source
Community. But still, developing of this software is driven
by my own needs. So, you could expect next release in a year or two ;)
.PP
It would be really nice if you could find some time and spare
it for rating this project on FreshMeat (see RESOURCES). Comments
are welcome too. I cannot promise that I will add new features to
lwatch immediately but any positive feedback will raise my motivation level up.
.PP
Thank you in advance for your time.
