lcdexec - LCDproc client to execute commands from the LCDd menu


lcdexec [-hf] [-c config] [-a addr] [-p port] [-r level] [-s bool]


lcdexec connects to LCDd (the LCDproc server) and adds a submenu to the LCDd main menu
that allows the user to select commands to be executed. You can access the menu by
pressing the menu key configured for LCDd.


lcdexec understands the following command line options., that override the corresponding
options given in the configuration file:

-c filename
Set the name of the config file to read, /etc/lcdexec.conf by default

-a address
Set the address of the host which LCDd is running on, localhost by default

-p port Set the port which LCDd is accepting connections on, 13666 by default

-f Run in foreground.

-r level
Set the reporting level to level, which is an integer representing the reporting
levels from 0 (critical errors only) to 5 (debug messages). Default is 2 (errors
and warnings only)

-s bool Report to syslog (1) or to stdout (0, default)


In addition to the command line options listed above lcdexec also takes options from a
configuration file.

This file is expected to have a "INI-file" like format with sections introduced by section
headers in square brackets and options lines consisting of key=value pairs.

Section and option names may contain only characters from the range [a-zA-Z0-9_], while
value strings may contain any printable character. Value strings with characters outside
the range [a-zA-Z0-9_] must be quoted with double quotes. To get a double quote or
backslashes in the string, they must be escaped by preceding it by a backslash.

The lcdexec configuration file needs at least two sections:

for the general options

for the top level of the menu hierarchy to be displayed.

The [lcdexec] section supports the following options:

The host name or IP address of the LCDd server to connect to. If not given,
server defaults to localhost.

Port of the server to connect to. The default value for port is 13666, the
LCDproc port.

Set the reporting level to level, which is an integer representing the reporting
levels from 0 (critical errors only) to 5 (debug messages). Default is 2 (errors
and warnings only)

Tell whether to report to syslog (TRUE) or to stderr (FALSE).

Tell whether to run in foreground (TRUE) or in background (FALSE). If not given,
the default is FALSE for daemon mode.

Set the display name for the main menu. If not given it defaults to lcdexec HOST,
where HOST is the hostname of the system lcdexec is running on.

Set the shell to use when executing programs. If not given, lcdexec tries to read
the environment variable SHELL. If that fails, it defaults to /bin/sh. Please
note that the shell given here must understand the option -c followed by the
command line to execute.

The [MainMenu] section and the sections it refers to define the menu hierarchy to be
displayed. Each menu and each menu entry in the menu hierarchy is defined as its own
section. Whether a given section is a sub-menu or a command entry is defined by the
option keys occurring in the section.

Menu / menu entry sections may contain the following options:

Defines a menu entry entry which is further specified in the section [entry].

Sections containing one or more Entry= options are menus.

Defines the system command command to be executed when this entry gets selected.

Sections containing an Exec= option are command entries.

The name of the menu entry to be displayed on the LCD. If this option is not
given, the the section header name is used (without the square brackets).

In command entries, this option tells whether to inform the user of the completion
of commands using an alert screen on the display. If not given, it defaults to
