1lcdexec(1) LCDproc suite lcdexec(1)

6 lcdexec - LCDproc client to execute commands from the LCDd menu
7
9 lcdexec [-hf] [-c config] [-a addr] [-p port] [-r level] [-s bool]
10
13 lcdexec connects to LCDd (the LCDproc server) and adds a submenu to the
14 LCDd main menu that allows the user to select commands to be executed.
15 You can access the menu by pressing the menu key configured for LCDd.
16
19 lcdexec understands the following command line options., that override
20 the corresponding options given in the configuration file:
21 -c filename
23 Set the name of the config file to read, /etc/lcdexec.conf by
24 default
25 -a address
27 Set the address of the host which LCDd is running on, localhost
28 by default
29 -p port Set the port which LCDd is accepting connections on, 13666 by
31 default
32 -f Run in foreground.
34 -r level
36 Set the reporting level to level, which is an integer repre‐
37 senting the reporting levels from 0 (critical errors only) to 5
38 (debug messages). Default is 2 (errors and warnings only)
39 -s bool Report to syslog (1) or to stdout (0, default)
41
43 In addition to the command line options listed above lcdexec also takes
44 options from a configuration file.
45 This file is expected to have a "INI-file" like format with sections
47 introduced by section headers in square brackets and options lines con‐
48 sisting of key=value pairs.
49 Section and option names may contain only characters from the range [a-
51 zA-Z0-9_], while value strings may contain any printable character.
52 Value strings with characters outside the range [a-zA-Z0-9_] must be
53 quoted with double quotes. To get a double quote or backslashes in the
54 string, they must be escaped by preceding it by a backslash.
55 The lcdexec configuration file needs at least two sections:
57 [lcdexec]
59 for the general options
60 [MainMenu]
62 for the top level of the menu hierarchy to be displayed.
63 The [lcdexec] section supports the following options:
65 Address=server
67 The host name or IP address of the LCDd server to connect to.
68 If not given, server defaults to localhost.
69 Port=port
71 Port of the server to connect to. The default value for port
72 is 13666, the LCDproc port.
73 ReportLevel=level
75 Set the reporting level to level, which is an integer repre‐
76 senting the reporting levels from 0 (critical errors only) to 5
77 (debug messages). Default is 2 (errors and warnings only)
78 ReportToSyslog=bool
80 Tell whether to report to syslog (TRUE) or to stderr (FALSE).
81 Foreground=bool
83 Tell whether to run in foreground (TRUE) or in background
84 (FALSE). If not given, the default is FALSE for daemon mode.
85 DisplayName=Display
87 Set the display name for the main menu. If not given it
88 defaults to lcdexec HOST, where HOST is the hostname of the
89 system lcdexec is running on.
90 Shell=/path/to/shell
92 Set the shell to use when executing programs. If not given,
93 lcdexec tries to read the environment variable SHELL. If that
94 fails, it defaults to /bin/sh. Please note that the shell
95 given here must understand the option -c followed by the com‐
96 mand line to execute.
97 The [MainMenu] section and the sections it refers to define the menu
99 hierarchy to be displayed. Each menu and each menu entry in the menu
100 hierarchy is defined as its own section. Whether a given section is a
101 sub-menu or a command entry is defined by the option keys occurring in
102 the section.
103 Menu / menu entry sections may contain the following options:
105 Entry=entry
107 Defines a menu entry entry which is further specified in the
108 section [entry].
109 Sections containing one or more Entry= options are menus.
111 Exec=command
113 Defines the system command command to be executed when this
114 entry gets selected.
115 Sections containing an Exec= option are command entries.
117 DisplayName=name
119 The name of the menu entry to be displayed on the LCD. If this
120 option is not given, the the section header name is used (with‐
121 out the square brackets).
122 Feedback=bool
124 In command entries, this option tells whether to inform the
125 user of the completion of commands using an alert screen on the
126 display. If not given, it defaults to no.
127
129 lcdexec.conf
130
133 In the configfile:
134 ## general options for lcdexec ##
136 [lcdexec]
137 # address of the LCDd server to connect to
138 Address=localhost
139 # Port of the server to connect to
141 Port=13666
142 # set reporting level
144 ReportLevel=2
145 # report to to syslog ?
147 ReportToSyslog=false
148 # run in foreground [default: false; legal: true, false]
150 Foreground=false
151 # display name for the main menu [default: lcdexec HOST]
153 #DisplayName=lcdexec
154 # main menu definition
157 [MainMenu]
158 # the Entry=... lines (one for each menu entry) tell it is a menu definition
159 Entry=EjectCD
160 Entry=ShutdownMenu
161 # definition of a command
163 [EjectCD]
164 # name to display in the menu instead of the section name
165 DisplayName="Eject CD-ROM"
166 # the Exec=... line tells that it is a command
167 Exec="umount /cdrom; cdeject"
168 # definition of a menu
170 [ShutdownMenu]
171 DisplayName="Shutdown menu"
172 # a menu contains an Entry=... line for each menu entry
173 Entry=Shutdown5min
174 Entry=Reboot5min
175 Entry=CancelShutdown
176 Entry=ShutdownNow
177 Entry=RebootNow
178 [Shutdown5min]
180 DisplayName="Shutdown in 5 minutes"
181 Exec="shutdown -h +5"
182 Feedback=yes
183 [Reboot5min]
185 DisplayName="Reboot in 5 minutes"
186 Exec="shutdown -r +5"
187 Feedback=yes
188 [CancelShutdown]
190 DisplayName="Cancel shutdown/reboot"
191 Exec="shutdown -c"
192 Feedback=yes
193 [ShutdownNow]
195 DisplayName="Shutdown now"
196 Exec="shutdown -h now"
197 [RebootNow]
199 DisplayName="Reboot now"
200 Exec="shutdown -r now"
201 Start lcdexec with: lcdexec -c /usr/local/etc/lcdexec.conf
204 This will allow you to eject the CD-ROM by opening the LCDd menu,
207 selecting "lcdexec" and selecting "Eject CD-ROM". Further it allows
208 you to do various shutdowns, among others the "Shutdown in 5 minutes"
209 by opening the LCDd menu, selecting "lcdexec", selecting "Shutdown
210 menu" and selecting "Shutdown in 5 minutes".

218 lcdexec is written by Joris Robijn and Peter Marschall. It is part of
219 the LCDproc suite.
220 The newest version of LCDproc should be available from here:

224
227 LCDproc is released as "WorksForMe-Ware". In other words, it is free,
228 kinda neat, and we don't guarantee that it will do anything in particu‐
229 lar on any machine except the ones it was developed on.
230 It is technically released under the GNU GPL license (you should have
232 received the file, "COPYING", with LCDproc) (also, look on
233 http://www.fsf.org/ for more information), so you can distribute and
234 use it for free -- but you must make the source code freely available
235 to anyone who wants it.
236 For any sort of real legal information, read the GNU GPL (GNU General
238 Public License). It's worth reading.
