This is a script that i build as a faster away to control basic functions of karma(enable, disable, status), web interface is awesome, but is a little slow...
Here is the source: http://linuxthings.site11.com/karma_script.sh
Install: wget http://linuxthings.site11.com/karma_script.sh && chmod +x karma_script.sh
USES: ./karma_script.sh enable / disable / status
OR
./karma_script.sh that shows a menu and you choose what to do...
