I wanted to get database file from the emulator. So, I tried to change the permission of package folder using adb shell. When I use the below command:

adb shell su -c chmod 777 /data/data/com.mypackage.test

It always returns: 

Chmod: need 2 arguments

I have changed permission some days ago using above command. But recently I'm always getting the above warning. I have searched a lot and found large information regarding using above command but no one mentioned about this warning issue.

I have overcome this issue instead of running adb shell su -c "chmod 777 /data", I run the adb shell first and then the following command : su -c "chmod 777 /data".
