Sending SMS from commandline / adb

[speeduploop]

Hi people!

Some time ago a few people asked about sending SMS from commandline...

So I wrote a little script ;)

sendsms

#!/system/bin/sh

if [ "$#" -ne 2 ]; then

  echo

  echo "----------- sendsms by speeduploop -----------"

  echo "- simple script to send sms from commandline -"

  echo "----------------------------------------------"

  echo "usage   : sendsms <number> <message>"

  echo "examples:"

  echo -e "  sendsms 01239878765 'hallo welt!!!'"

  echo -e "  sendsms '01239878765' hallo\ welt!!!"

  echo -e "  sendsms '01239878765' 'hallo welt!!!'"

  echo -e "  sendsms +491239878765 'hallo\\\nwelt!!!'"

  echo

  exit 1

fi

echo -ne "\e" > /dev/smd8

echo -ne "at+cmgf=1\r\n" > /dev/smd8

echo -ne "at+cmgs=\"$1\"\r\n" > /dev/smd8

echo -ne "$2\x1a" > /dev/smd8

sleep 1

echo -ne "at+cmgf=0\r\n" > /dev/smd8

Without arguments it shows the usage-help...

shell@Nokia 8110 4G:/data/opt/bin $ ./sendsms                                  

----------- sendsms by speeduploop -----------

- simple script to send sms from commandline -

----------------------------------------------

usage   : sendsms <number> <message>

examples:

  sendsms 01239878765 'hallo welt!!!'

  sendsms '01239878765' hallo\ welt!!!

  sendsms '01239878765' 'hallo welt!!!'

  sendsms +491239878765 'hallo\nwelt!!!'

But yes... it usually needs root.

If you don't want to use root every time to send a SMS you can also lower the permissions of the device-node:

chmod 555 /dev/smd8

You need this once after every reboot - so probably in your init-file.

(on a bootstrapped device /data/opt/init)

After that you can use the script without root permissions -- even over adb from a PC!

--> on GerdaOS, stock-firmware with patched adbd or via a telnet-backdoor it will just work...

have fun!

thank you speeduploop!

the file has to be uploaded ?

[speeduploop]

Yes - it's a script to run directly on the device.

--> you can push it either to /data/local/tmp for temp-use or to /data/opt if you have bootstrapped...

(don't forget exec-permissions --> 'chmod +x sendsms')

Or adapt the last 6 lines of code and integrate it in own scripts..

[perry]

/data/opt do not exist

root@Nokia 8110:/data     mkdir opt

it is right ?

[speeduploop]

yes... (my bootstrapon-script uses this by default to be able to set an additional init-script...)

mkdir -p /data/opt
chmod 777 /data/opt

the second line allows that you can easily push/pull with adb...

--> I also have /data/opt/bin ;)

[perry]

I'am on gerdaOs 

is the chmod 777 /data/opt necessary ?

[speeduploop]

IIRC adb on GerdaOS is patched to 'root-only'... so no.

The chmod is only needed to allow 'normal' adb to access it.

[perry]

/system/bin/sh: sendsms: not found

how the system know the file is in /data/opt/ ?

[speeduploop]

it doesn't unless you tell it... like usual.

Just use full path or move it to /system/bin.

(I usually put binaries/scripts I use often in /system/bin -- or use full path for things I don't use often)

[perry]

like this:

data/opt/sendsms sendsms 0049xxxxx6215 'hello world'

[speeduploop]

If it's in /data/opt then only one 'sendsms'...

/data/opt/sendsms 0049xxxxx6215 'hello world'

or even - from a PC:

adb shell /data/opt/sendsms 0049xxxxx6215 'hello world'

[perry]

oh yes! thanks.

One thing -- because I recognized a german number: there are some problems with non-ascii characters...

(so some german-umlauts will break it...)
