lcdproc - system status information client


lcdproc [-hfv] [-c config] [-s host] [-p port] [-e delay] [screen ...]


lcdproc is the client in the LCDproc suite that displays information about the local
system's status on an LCD that is connected to an LCDd server daemon.

Due to the client-server architecture it does not matter whether the LCDd daemon runs on
the local machine or on a remote system.

Most settings of lcdproc are configured through its configuration file /etc/lcdproc.conf,
some of them can be overridden using command line options.

Before running lcdproc you should carefully read through that file and modify the settings
therein according to your needs.

When compiled appropriately, some aspects of lcdproc can even configured at run time using
a menu on the LCD.

Currently, only Linux, the BSD variants FreeBSD, NetBSD, OpenBSD and Darwin as well as
Solaris are supported, but not all features may be available on all platforms.


lcdproc understands these command line options:

-c config
Use a configuration file other than /etc/LCDd.conf

-s host
Connect to the LCDd server on host, instead to the one listed in te Server
parameter in the config file's [lcdproc] section. If not given here and not
specified in the config file or if the default config file does not exist, it
defaults to 'localhost.

-p port
Use port port when connecting to the LCDd server on host. This option overrides
the Port parameter in the config file's [lcdproc] section. Without a default
config file or when not set in the config file, it defaults to the LCDproc port

-f Run in the foreground, overriding the Foreground parameter in the config file's
[lcdproc] section. The default, if not in the config file or without a config
file, is to daemonize lcdproc as it is intended to display the system information
in the background.

-e delay
Sleep delay in 100ths of seconds between updating screens in an update cycle. This
option overrides the Delay parameter in the config file's [lcdproc] section. When
not given and not in the config file, it defaults to 0.

-h Show help screen.

-v Print the version of lcdproc and exit.

screen can be one of the following:

C CPU show detailed CPU usage

P SMP-CPU CPU usage overview: one line per CPU, especially useful on SMP

G CPUGraph CPU histogram

L Load Load histogram

M Memory memory & swap usage

S ProcSize memory usage of 5 biggest processes

D Disk filling level of the mounted file systems

I Iface network interface usage

B Battery battery status

T TimeDate time & date information

O OldTime old time screen

U Uptime uptime screen

K BigClock big clock

N MiniClock minimal clock

A About credits page

On the command line you may either use the short or the long screen name. In the
config file, the long names are used as section labels to configure the screens

You may also prefix the screen names with an exclamation mark '!' to disable a
screen that was activated in the config file instead of activating a disabled one.


lcdproc C M D '!L'

With the command line specified above, lcdproc loads the default configuration file,
connects to the LCDd server specified therein and then displays the following screens in
addition to those activated in the configuration file on the LCD:

* detailed CPU Usage

* Memory & swap usage

* filling level of the mounted file systems


* Load histogram

screen is disabled and therefore not shown in the display. (The quotes are not part of
lcdproc's command line syntax; they are required to disable special interpretation of the
exclamation mark by the shell).
