Desktop Command Execution widget is one of the most useful widgets on your Maemo desktop. It can be used to show certain information (for example battery level in percentage) or as a button which can be used for example to disconnect active internet connection (you need to tap 3 times and also wait for menus to appear without this widget). Therefore it can replace many other applications/widgets/applets and you can also make something new. Here you'll find a collection of scripts that can be added to the widget. The discussion about the widget is [http://talk.maemo.org/showthread.php?t=39177 on the forum].

Scripts are also compatible with [[Queen BeeCon Widget]] which has extended graphic and cosmetic functionality, but is far more complicated.
 
==Making your own scripts==
==Making your own scripts==
-
===Scripts without output===
+
When there's no output (for example if you're using widget as a button and you use dbus call), the widget displays "Invalid Command". This can be most easily avoided if you pipe echo "" at the end of the command. Example:
-
 
+
-
When there's no output (for example if you're using widget as a button and you use D-Bus call) the widget displays "Invalid Command". This can be most easily avoided if you pipe echo "" at the end of the command. This is also usable if your script produces unwanted output (D-Bus reply for example).
+
  dbus-send -options -moreoptions | echo ""
  dbus-send -options -moreoptions | echo ""
-
Collection of D-Bus calls can be found on [[Phone control]] wiki page. The basic principle for making a script for DCEW is the same as above (D-Bus command and piping an echo).
+
This also works:
-
===Scripts with long output===
+
dbus-send -options -moreoptions; echo ""
-
Some scripts may create multiple lines which are too long to be displayed on a single line. The widget will not wrap these. In order to wrap them you can use the fold command:
+
...but the piping is preferred for buttons as it doesn't display ANY output (some dbus calls work only with reply). All of the dbus commands should be working in the same way. Collection of these can be found on [[Phone control]] wiki page. The basic principle is the same as above (dbus command and piping an echo).
-
+
-
command-that-produces-long-lines | fold -s -w 100
+
-
The 80 in that instance is the maximum length of the line, which you can change. The -s option makes fold word wrap with spaces. More information is available from the [http://unixhelp.ed.ac.uk/CGI/man-cgi?fold fold man page].

====Uptime====
 +
To display uptime and load:
 +
uptime | cut -c14-
 +
 +
To display only uptime:
 +
uptime | sed -e 's/ ..:..:.. up //' -e 's/, load average: ...., ...., ....//'
 +

====Battery (several scripts)====
All battery scripts are collected here. Pick the one which suits your needs. Examples of the output values are under each one.

Install this as e.g. /usr/local/bin/bqbattery, make it executable and point DCEW to it. This is designed to work whether or not you have the bq27x00_battery module loaded, but if you don't, then you'll need to install the i2c-tools package, and then chmod 4755 /usr/sbin/i2cget (meaning i2cget runs as root even when we invoke it as user from DCEW).

Internal IPs are obtained from the ifconfig and external IPs are obtained from the internet, because gprs0 IP which you can get with ifconfig is often from private address range, because mobile operators like to use NAT.

===Cellular signal===

To display top $N programs (output of `top` command). This will always exclude top itself ''(which note is quite processor intensive, so you probably don't want this updating too often)''. Replace (3+$N) and $N with appropriate values -- for example, to show top two applications, 5 and 2. Alternately you can define $N, if you're up on shell scripting.

-
This one shows two timezones in format ''London: 13:04 | Denver: 06:04''
+
Valid TZ values are taken from the [http://en.wikipedia.org/wiki/Tz_database zoneinfo (Olson) database].
-

-
echo "London:" `export TZ="Europe/London"; date +%R` "| Denver:" `export TZ="America/Denver"; date +%R`

London and Denver are taken as an example. TZ values can be found on [[:wikipedia:List_of_tz_database_time_zones|Wikipedia]].

===Uptime and load===
+
-
 
+
-
These scripts are formatproof meaning that they display what they're supposed to no matter what format is command "uptime" outputting. Not all scripts found are like that, because "uptime" command is a little bit complicated for scripted text processing. For example when the system is running under one hour only "x min" is shown, when it is running under one day "hour:min:sec" is shown and after that it is shown in format "x days, hour:min:sec".
+
-
 
+
-
 
+
-
====Both====
+
-
 
+
-
uptime | sed -e 's/.*up */uptime: /' -e 's/ average//' -e 's/  / /'
+
-
 
+
-
 
+
-
====Uptime====
+
-
 
+
-
uptime | sed -e 's/.*p *//' -e 's/, l.*//' -e 's/  / /'
+
-
 
+
-
 
+
-
====Load====
+
-
 
+
-
uptime | sed 's/.*e: //'
+
-
 
+
-
 
+
-
===Boot reason===
+
-
 
+
-
cat /proc/bootreason
+
-
 
+
-
 
+
-
===Boot count===
+
-
 
+
-
cat /var/lib/dsme/boot_count
+
-
 
+
-
 
+
-
===Temperature===
+
-
 
+
-
CPU's thermal sensors are not accessible, but there is one near the battery. This commands displays output of its readings, but IT IS NOT RELIABLE, because it doesn't always work. Sometimes the value returned is wrong or constant. It needs to be tested further.
+
-
 
+
-
cat /sys/devices/platform/omap34xx_temp/temp1_input | awk '{ sub(/-/,""); print $1" °C"}'
+
-
 
+
-
There is a working way now to read the correct temperature, but it is working only on a newer titan's kernels (normal, overclock, undervoltage). The bq27x00_battery module has to be loaded first.
+
-
 
+
-
echo `cat /sys/class/power_supply/bq27200-0/temp` °C
+
-
 
+
-
with a comma :
+
-
 
+
-
echo `cat /sys/class/power_supply/bq27200-0/temp` °C | sed 's/\B[0-9]\{1\}/&,/'
+
-
 
+
-
===Top processes===
+
-
 
+
-
This script displays top ''N'' CPU consuming processes. It excludes top itself, which is quite processor intensive so you probably don't want this updating too often. Modify ''N=3'' at the start to display different number of processes.
+
-
 
+
-
N=3; top -bn 1 | grep -v top | head -n $(($N+4)) | tail -n $(($N+1)) | awk '{OFS = "\t"} {print $7,$8}'
+
-
 
+
-
 
+
-
===Random Number Generator===
+
-
 
+
-
This script displays a random number between 0 and ''M'' (''M'' included)
+
-
 
+
-
M=6; dd if=/dev/urandom bs=1 count=4 2>/dev/null | od -l | awk -v M=$M '{M++;print $2<0?-$2%M:$2%M;exit}'
+
-
 
+
-
 
+
-
 
+
-
===Ping a Host===
+
-
Preferred method. Install netcat from [http://wiki.maemo.org/Documentation/devtools/maemo5#Installation]
+
-
 
+
-
if (nc -zw1 192.168.2.1 80);then echo up;else echo down;fi
+
-
 
+
-
Alternate method. Ping has a long timeout when down. Warning: it will block the desktop while running.
+
-
 
+
-
if (echo 'ping -c1 192.168.2.1' | rootsh /bin/sh  2>&1 >/dev/null);then echo up;else echo down;fi

==Scripts for buttons==
+
 +
===Buttons===
Make sure that update policy for button widgets is set only to "update when clicked". "Update when switched to desktop", "update interval" and "network presence" should be disabled to avoid automatic actions. Also keep in mind that widgets are executed at every boot so they can for example automatically disable Wi-Fi when phone boots.

"Update when switched to desktop", "update interval" and "network presence" should be disabled to avoid automatic actions. Also keep in mind that widgets are executed at every boot so they can for example automatically disable Wi-Fi when phone boots.
-
 
-
There is a bug in version 0.9 or lower which prevents you from using DCEW widgets as buttons, because they get activated (pressed) automatically all the time. You have to make sure DCEW is at least version 1.0, to check which version you have installed do this: dpkg -l desktop-cmd-exec.

You get the opposite behaviour (enable vibrating alert) simply by replacing "Off" two times by "On".

===Set maximum CPU frequency===
 
-
 
-
echo "echo 600000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq" | sudo gainroot | echo ""
 
-
 
-
Replace 600000 with desired maximum frequency. This is usable with the new overclocking kernels if you wish to manually change the maximum frequency to which processor can scale. Pay attention to the two exceptions in titan's kernels (124999 and 599000). The list of available frequencies on your device/kernel can be obtained with command:
 
-
 
-
awk '{print $1/1000" MHz"}' /sys/devices/system/cpu/cpu0/cpufreq/stats/time_in_state

Warning: Consult forums before you try this, because currently DCEW executes some (all?) commands at startup. This will be optional in next version. Making a reboot button on current DCEW version could result in endless reboot loop.
 
-
 
-
====A much safer way====
 
-
write a file with the following content
 
-
 
-
  #!/bin/sh
 
-
  zenity --question --title="reboot?" --text="are you sure ?"
 
-
  if [ $? -eq 0 ]; then
 
-
  echo "reboot" | sudo gainroot | echo ""
 
-
  fi
 
-
 
-
save it to '''/bin/ask-reboot'''
 
-
then execute :
 
-
  chmod +x ask-reboot
 
-
 
-
now add a new command widget with the command '''"ask-reboot"''' .
 
-
 
-
make sure you uncheck the folowing check boxes
 
-
* update on boot
 
-
* update when switched to desktop

== Scripts to pull data from remote web sites ==
 
-
 
-
Although these are also scripts to display information, of a sort, I've created  a separate section for scripts that use DCEW to replace the use of a mobile web browser in certain situations. My first take on this is a set of scripts / widgets to enable me to access Transport for London's live bus travel information.
 
-
 
-
=== Transport for London - Live Bus Departures ===
 
-
 
-
==== Display departures for multiple local bus stops ====
 
-
 
-
Transport for London recently launched a mobile Web interface to their live bus departures information, and it's pretty good, but it can be a pain navigating to the bus stop that you want. This script uses DCEW to display data from multiple local bus stops, and to switch between them (by iterating over a list of them) on touching the widget.
 
-
#!/bin/sh
 
-
 
-
BUS_STOPS="50713 48598 53221 74407"
 
-
 
-
if [ -r "/tmp/.bus_stops" ]; then
 
-
BUS_STOPS=`cat /tmp/.bus_stops`;
 
-
else
 
-
echo $BUS_STOPS > /tmp/.bus_stops;
 
-
chmod 777 /tmp/.bus_stops
 
-
fi
 
-
 
-
LOOP=0
 
-
if [ -r "/tmp/.countdown" ]; then
 
-
LOOP=`cat /tmp/.countdown`;
 
-
fi
 
-
let LOOP=$LOOP+1;
 
-
STOPCOUNT=`echo $BUS_STOPS | wc -w`;
 
-
if [ "$LOOP" -gt "$STOPCOUNT" ]; then
 
-
  LOOP=1;
 
-
fi;
 
-
echo $LOOP >/tmp/.countdown
 
-
chmod 777 /tmp/.countdown
 
-
 
-
THISTIME=`echo $BUS_STOPS | cut -d" " -f $LOOP`;
 
-
 
-
lynx -dump -nolist http://m.countdown.tfl.gov.uk/arrivals/$THISTIME | grep -A10 "Buses dep" | sed -e "s/^  //g" | grep [a-z] | egrep -v "(Refresh|See\ map|Buses\ departing)"
 
-
 
-
==== Display departures for multiple lists of multiple bus stops ====
 
-
 
-
This second script, designed to be used with an additional DCEW on the same screen as the first, changes the list of bus stops associated with the script above and displays the place name with which they are associated. So, using this second widget, I can switch the first widget between the list of bus stops that I require in one place, and the list that I require in another. This limits the length of any individual list and will eventually let me access four or five lists of stops according to where I happen to be.

==== Multiple lists of multiple stops with file-based configuration ====
 
-
 
-
This third script combines the functionality for both of the above widgets from a single script, to be installed as e.g. /usr/local/bin/countdown, and moves the bus stop configuration from variables to flat files, arranged by placename. It also adds some command-line functionality (not yet widgetised), which enables you to configure a given placename from the 5-digit code of a single bus stop.

The idea here is that I go to a new place, let's say Putney, and I get off at The Embankment, which turns out to be stop 75040. I can now run:
 
-
 
-
# countdown --near 75040
 
-
 
-
and override the current list of bus stops with the nine stops nearest to stop 75040, or, to store the configuration, I can run
 
-
 
-
# countdown --near 75040 "Putney"
 
-
 
-
and the script will save a new location called Putney which I can then switch using the previously described switching functionality via DCEW. All that needs to be done to configure the script for the places you visit is to pick a bus stop that is fairly central to that location and run with --near to store the configuration.
