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
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 overriden using command line
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:
Use a configuration file other than /etc/LCDd.conf
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.
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 13666.
-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
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 systems.
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 further.
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).

LCDproc was originally written by William Ferrell (firstname.lastname@example.org)
andr Scott Scriven (email@example.com).
Since that time various people have contributed to LCDproc.
The newest version of LCDproc should be available from here:
LCDproc is released as "WorksForMe-Ware". In other words, it is free,
kinda neat, and we don’t guarantee that it will do anything in
particular on any machine except the ones it was developed on.
It is technically released under the GNU GPL license (you should have
received the file, "COPYING", with LCDproc) (also, look on
http://www.fsf.org/ for more information), so you can distribute and
use it for free -- but you must make the source code freely available
to anyone who wants it.
For any sort of real legal information, read the GNU GPL (GNU General
Public License). It’s worth reading.
