Ubuntu Manpage: lcdexec - LCDproc client to execute commands from the LCDd menu

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.

EXAMPLES

       In the configfile:

       ## general options for lcdexec ##
       [lcdexec]
       # address of the LCDd server to connect to
       Address=localhost

       # Port of the server to connect to
       Port=13666

       # set reporting level
       ReportLevel=2

       # report to to syslog ?
       ReportToSyslog=false

       # run in foreground [default: false; legal: true, false]
       Foreground=false

       # display name for the main menu [default: lcdexec HOST]
       #DisplayName=lcdexec

       # main menu definition
       [MainMenu]
       # the Entry=... lines (one for each menu entry) tell it is a menu definition
       Entry=EjectCD
       Entry=ShutdownMenu

       # definition of a command
       [EjectCD]
       # name to display in the menu instead of the section name
       DisplayName="Eject CD-ROM"
       # the Exec=... line tells that it is a command
       Exec="umount /cdrom; cdeject"

       # definition of a menu
       [ShutdownMenu]
       DisplayName="Shutdown menu"
       # a menu contains an Entry=... line for each menu entry
       Entry=Shutdown5min
       Entry=Reboot5min
       Entry=CancelShutdown
       Entry=ShutdownNow
       Entry=RebootNow

       [Shutdown5min]
       DisplayName="Shutdown in 5 minutes"
       Exec="shutdown -h +5"
       Feedback=yes

       [Reboot5min]
       DisplayName="Reboot in 5 minutes"
       Exec="shutdown -r +5"
       Feedback=yes

       [CancelShutdown]
       DisplayName="Cancel shutdown/reboot"
       Exec="shutdown -c"
       Feedback=yes

       [ShutdownNow]
       DisplayName="Shutdown now"
       Exec="shutdown -h now"

       [RebootNow]
       DisplayName="Reboot now"
       Exec="shutdown -r now"

       Start lcdexec with: lcdexec -c /usr/local/etc/lcdexec.conf

       This will allow you to eject the CD-ROM by opening the LCDd menu, selecting "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", selecting "Shutdown
       menu" and selecting "Shutdown in 5 minutes".
