NAME¶
lcdexec - LCDproc client to execute commands from the LCDd menu
SYNOPSIS¶
lcdexec [
-hf] [
-c config] [
-a addr]
[
-p port] [
-r level] [
-s bool]
DESCRIPTION¶
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.
OPTIONS¶
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)
USAGE¶
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:
- [lcdexec]
- for the general options
- [MainMenu]
- for the top level of the menu hierarchy to be displayed.
The
[lcdexec] section supports the following options:
- Address=server
- The host name or IP address of the LCDd server to connect to. If not
given, server defaults to localhost.
- Port=port
- Port of the server to connect to. The default value for port is
13666, the LCDproc port.
- ReportLevel=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)
- ReportToSyslog=bool
- Tell whether to report to syslog (TRUE) or to stderr (FALSE).
- Foreground=bool
- Tell whether to run in foreground (TRUE) or in background (FALSE). If not
given, the default is FALSE for daemon mode.
- DisplayName=Display
- 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.
- Shell=/path/to/shell
- 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:
- Entry=entry
- Defines a menu entry entry which is further specified in the
section [entry].
Sections containing one or more Entry= options are menus.
- Exec=command
- Defines the system command command to be executed when this entry
gets selected.
Sections containing an Exec= option are command entries.
- DisplayName=name
- 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).
- Feedback=bool
- 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 no.

"lcdexec" and selecting "Eject CD-ROM". Further it allows
you to do various shutdowns, among others the "Shutdown in 5
minutes" by opening the LCDd menu, selecting "lcdexec",
