Closing WhatsApp on Nokia E72

Binny V A — Thu, 15 Mar 2012 19:45:57 +0000

First install the app called MobileGuard. Its a cool app. I’ll recommend it even if you want to keep whatsapp. Next, open MobileGuard, and go to Clean Spam > Memory Cleaning > Clear in Batch > Select WhatsApp. Now select the ‘Off’ option. This should close the app and all its services

Keep in mind that whatsapp will start again when you restart your phone. If you want to turn that off, go to Boot Mgr in Mobile Guard and disable it.

Convert RAW files to JPEG in batch. Convert all files in a folder using a command. For this to work, first you must have ‘ufraw’ package installed. sudo apt-get install ufraw or sudo yum install ufraw depending on your OS.


find . -type f -name "*.CR2" -exec ufraw-batch --out-type=jpeg '{}' \;

Send One Line From a Text File as as SMS Every 10 Mins

Binny V A — Thu, 11 Aug 2011 18:08:19 +0000

This command will send a line from a given text file one every 10 mins as an SMS to a given number.


i=1; while [ 1 ]; do sms INSERT_PHONE_NUMBER "$(cat "/home/binnyva/sms.txt"|head -n$i|tail -n1)"; sleep 10m; i=$(expr $i + 1); done

Script calls the command ‘sms’ – you can define that command however you want. In my case, its a variation of this script.
