Desktop Command Execution Widget scripts

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 on the forum.

Making your own scripts
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:

dbus-send -options -moreoptions | echo ""

This also works:

dbus-send -options -moreoptions; echo ""

...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).

Uptime
uptime|cut -d" " -f4-|sed 's/\\, *load.*//'

Battery level percentage
hal-device bme | awk -F"[. ]" '$5 == "is_charging" {chrg = $7}; $5 == "percentage" {perc = $7} END if (chrg == "false") {print perc " %"} else {print "Chrg"}'

This one is slightly modified as the default one. The percentage sign (%) is added so the widget doesn't have an ugly name like Battery(%) or it doesn't have to have a name at all and you still know what is it about.

Here is a more simple one showing only percentage, not also "Chrg" when charging.

hal-device bme | grep perc | awk '{print $3" %"}'

Battery level in mAh
hal-device bme | grep battery.reporting | awk -F. '{print $3}' | sort | awk '$1 == "current" { current = $3}; $1== "last_full" {print current "/" $3 " mAh"}'

This one is slightly modified as the default one. The unit (mAh) is added so the widget doesn't have an ugly name like Battery(mAh) or it doesn't have to have a name at all and you still know what is it about. The second value (design charge) is also changed to last full charge. This is important because you can also monitor battery wear level with that. So the values in this script are "current charge"/"last full charge" mAh.

Boot reason
cat /proc/bootreason

Boot count
cat /var/lib/dsme/boot_count

External (WAN) IP
WAN IP only:

wget -q -O - api.myiptest.com | awk -F"\"" '{print $4}'

WAN IP, ISP and country code:

wget -q -O - api.myiptest.com | awk -F"\"" '{print $4 " ("$12" "toupper($28)")"}'

Internal (LAN) IP
/sbin/ifconfig | grep "inet addr" | awk -F: '{print $2}' | awk '{print $1}'

Rootfs (percentage)
df | awk '$1 == "rootfs" {print $5}'

Rootfs (free)
df -h | awk ' $1 == "rootfs" {print $4"B"}'

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.

Connect internet (show connections)

Enable/disable Wi-Fi
rootsh /path/to/script/enable-disable_wi-fi.sh | echo ""

enable-disable_wi-fi.sh:
