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).
Scripts to display information
Battery
All battery scripts are collected here. Pick the one which suits your needs. Examples of the output values are under each one.
There are 2 values for full battery capacity available. First one is design charge in mAh, which is always the same (1273 mAh). The second one is the one used in these scripts and it is the full charge from last charging. With displaying this one you can also monitor battery wear level.
Battery percentage level is calculated using first value and is therefore less accurate, that's why you cannot achieve 100% full battery, but only about 95%. After some time the full percentage will be even lower.
But last full charge value has one disadvantage. This is that after a reboot the phone forgets this value and the value returned is 0. It shows the proper value after next charging.
Percentage, current and last full charge
hal-device bme | awk '/l.p/ {perc = $3}; /g.c/ {curr = $3}; /g.la/ {last = $3}; /s_c/ {isch = $3} END if (isch == "false") {print perc" % ("curr"/"last" mAh)"} else {print "Charging"}'
Output example: 83 % (1000/1200 mAh), when charging Charging
Percentage and current charge
hal-device bme | awk '/l.p/ {perc = $3}; /g.c/ {curr = $3}; /s_c/ {isch = $3} END if (isch == "false") {print perc" % ("curr" mAh)"} else {print "Charging"}'
Output example: 83 % (1000 mAh), when charging Charging
Percentage
hal-device bme | awk '/l.p/ {perc = $3}; /s_c/ {isch = $3} END if (isch == "false") {print perc" %"} else {print "Chrg"}'
Output example: 83 %, when charging Chrg
Current and last full charge
hal-device bme | awk '/g.c/ {curr = $3}; /g.la/ {last = $3} END {print curr"/"last" mAh"}'
Output example: 1000/1200 mAh
Current charge
hal-device bme | awk '/g.c/ {print $3" mAh"}'
Output example: 1000 mAh
Last full charge
hal-device bme | awk '/g.la/ {print $3" mAh"}'
Output example: 1200 mAh
Date
date +"%d.%m.%Y"
This command will show the date in format (for example) 01.10.2010. You can define your own format (between the quotation marks). Possible options are described on manpage.
IP
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.
External (WAN) and internal (LAN)
echo WAN IP: `wget -q -O - api.myiptest.com | awk -F"\"" '{print $4" ("$12" @ "$20", "toupper($28)")"}'`; echo LAN IP: `/sbin/ifconfig | awk '/Bc/ {print $2}' | cut -c6-`
You can replace WAN IP part of the script with the commands below to display it without additional info.
External (WAN)
wget -q -O - api.myiptest.com | awk -F"\"" '{print $4}'
Output example: 1.2.3.4
wget -q -O - api.myiptest.com | awk -F"\"" '{print $4 " ("$12" "toupper($28)")"}'
Output example: 1.2.3.4 (ISP CountryCode)
wget -q -O - api.myiptest.com | awk -F"\"" '{print $4" ("$12" @ "$20", "toupper($28)")"}'
Output example: 1.2.3.4 (ISP @ City, CountryCode)
Internal (LAN)
/sbin/ifconfig | awk '/Bc/ {print $2}' | cut -c6-
This one displays only wlan0 IP (used for SSH, WinSCP, VNC... in LAN).
Disk usage
rootfs (256MB /)
Percentage used:
df | awk '$1 == "rootfs" {print $5}'
Free space:
df -h | awk '$1 == "rootfs" {print $4}'
Internal memory for user data (27GB /home/user/MyDocs)
Percentage used:
df /home/user/MyDocs | awk '/My/ {print $5}'
Free space:
df -h /home/user/MyDocs | awk '/My/ {print $4}'
Internal memory for application data (2GB /home)
Percentage used:
df /home | awk '/ho/ {print $5}'
Free space:
df -h /home | awk '/ho/ {print $4}'
Memory card (/media/mmc1)
Percentage used:
df /media/mmc1 | awk '/mm/ {print $5}'
Free space:
df -h /media/mmc1 | awk '/mm/ {print $4}'
Uptime
To display uptime and load:
uptime | cut -c14-
To display only uptime:
uptime | sed -e 's/ ..:..:.. up //' -e 's/, load average: ...., ...., ....//'
Boot reason
cat /proc/bootreason
Boot count
cat /var/lib/dsme/boot_count
top
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 $N, if you're up on shell scripting.
top -bn 1 | grep -v top | head -n (3+$N) | tail -n $N
World time
Time in a particular timezone can be shown with the date command; for example, for the current time in London use:
export TZ="Europe/London" date "+%H:%M"
A more complex usage, showing London: 04:21 | Denver: 22:21
echo "London: " `/usr/bin/worldtime Europe/London` " | Denver: " `/usr/bin/worldtime America/Denver`
with a shell script /usr/bin/worldtime something like this:
#!/bin/sh if [ $# -gt 1 ] then DATEFORMAT="$2" else DATEFORMAT="%H:%M" fi if [ $# -gt 2 ] then TIMETOSHOW="-d \"$3\"" else TIMETOSHOW="" fi export TZ=$1 date "+$DATEFORMAT" $TIMETOSHOW
Valid TZ values are taken from the zoneinfo (Olson) database.
Scripts for 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.
Networking
Connect internet (show connections)
dbus-send --system --type=method_call --dest=com.nokia.icd_ui /com/nokia/icd_ui com.nokia.icd_ui.show_conn_dlg boolean:false | echo ""
Disconnect internet
dbus-send --system --dest=com.nokia.icd /com/nokia/icd_ui com.nokia.icd_ui.disconnect boolean:true | echo ""
Enable/disable Wi-Fi
rootsh /path/to/script/enable-disable_wi-fi.sh | echo ""
enable-disable_wi-fi.sh:
#!/bin/sh out=`ifconfig wlan0` if [ $? -eq "0" ] ; then if [ `echo "$out" | grep -c RUNNING` -gt "0" ] ; then run-standalone.sh dbus-send --system --dest=com.nokia.icd /com/nokia/icd_ui com.nokia.icd_ui.disconnect boolean:true fi ifconfig wlan0 down rmmod wl12xx run-standalone.sh dbus-send --type=method_call --dest=org.freedesktop.Notifications /org/freedesktop/Notifications org.freedesktop.Notifications.SystemNoteInfoprint string:'Wi-Fi disabled' exit 2 else modprobe wl12xx wl1251-cal stop wlancond start wlancond ifconfig wlan0 up run-standalone.sh dbus-send --system --type=method_call --dest=com.nokia.icd_ui /com/nokia/icd_ui com.nokia.icd_ui.show_conn_dlg boolean:false exit 0 fi
Don't forget to make it executable.
Lock screen and keys
dbus-send --system --type=method_call --dest=com.nokia.mce /com/nokia/mce/request com.nokia.mce.request.req_tklock_mode_change string:"locked" | echo ""
Radio mode
2G/3G
sh /path/to/script/2g3g.sh | echo ""
2g3g.sh:
#!/bin/sh
get=`dbus-send --system --print-reply --type=method_call --dest=com.nokia.phone.net /com/nokia/phone/net Phone.Net.get_selected_radio_access_technology | awk '/b/ {print $2}'`
if [ `echo $get` -eq 1 ]; then
dbus-send --system --type=method_call --dest=com.nokia.phone.net /com/nokia/phone/net Phone.Net.set_selected_radio_access_technology byte:2
else
dbus-send --system --type=method_call --dest=com.nokia.phone.net /com/nokia/phone/net Phone.Net.set_selected_radio_access_technology byte:1
fi
When 3G or Dual mode is active, the script will switch to 2G. And when 2G is active, it will switch to 3G.
Don't forget to make the script executable.
2G
dbus-send --system --type=method_call --dest=com.nokia.phone.net /com/nokia/phone/net Phone.Net.set_selected_radio_access_technology byte:1 | echo ""
3G
dbus-send --system --type=method_call --dest=com.nokia.phone.net /com/nokia/phone/net Phone.Net.set_selected_radio_access_technology byte:2 | echo ""
Dual
dbus-send --system --type=method_call --dest=com.nokia.phone.net /com/nokia/phone/net Phone.Net.set_selected_radio_access_technology byte:0 | echo ""
Update e-mail
sh /path/to/script/email.sh | echo ""
email.sh:
Make it executable and insert proper IAP_ID in the script. What it does is that it checks whether the phone is connected to the internet and if it is, send and receive is performed and if it is not, the defined connection (IAP_ID) is used to connect, then send and receive is performed and script waits about minute and a half (Modest e-mail client which N900 uses is slow in this aspect) and then disconnects internet.
#!/bin/sh
get=`/sbin/route | awk '/au/ {print $1}'`
if [ `echo $get` = default ]; then
dbus-send --type=method_call --dest=com.nokia.modest /com/nokia/modest com.nokia.modest.SendReceive
else
dbus-send --type=method_call --dest=org.freedesktop.Notifications /org/freedesktop/Notifications org.freedesktop.Notifications.SystemNoteInfoprint string:"Updating e-mail"

dbus-send --system --dest=com.nokia.icd /com/nokia/icd_ui com.nokia.icd_ui.disconnect boolean:true
dbus-send --type=method_call --dest=org.freedesktop.Notifications /org/freedesktop/Notifications org.freedesktop.Notifications.SystemNoteInfoprint string:"E-mail updated"
fi
Reboot
rootsh reboot | echo ""
FM transmitter
Enable/disable
/usr/bin/fmtx_client -p$(if [ $(cut -d. -f1 /proc/uptime ) -lt 100 ]; then echo 0; else /usr/bin/fmtx_client | /bin/grep -q '^state=enabled' ; echo $? ; fi) | /usr/bin/awk -F '=' '($1=="state") {print $2}'
Note: when you reboot the device, this script waits 100 seconds before you can turn the transmitter on/off again.
Increase power
rootsh echo 118 > /sys/class/i2c-adapter/i2c-2/2-0063/power_level | echo ""
