Okay, BrokenSmile. Look at it this way, you are entering the commands WRONG.

When I say "kill <process ID>" I mean you are going to enter something like "kill 9127". When you type "ps | grep AppLock" it will give you a list of apps that are running with a number next to their name. This is the number that you put after "kill ". In your case the only one that gets shown is "2060 root 2828 S grep AppLock", so you DONT need to run "kill" but if you say had one that went "2060 root 2828 S /opt/applock/AppLock -d" you would enter "kill 2060"

Also, I corrected myself previously, the "chown" command should be: "chown user:users settings.db"

To remove applock using the terminal just run the following:
It should remove all the files EXCEPT the settings.db file. To remove that run this:
I am putting the finishing touches on v0.3.1 so if you can be patient I will try and have it released by this evening, otherwise I will have an internet connection again on Friday, so I will release it then.
