How to forcefully quit or kill an application or program.

In Ubuntu 11.10 we have an application “Force Quit” which is not available in Ubuntu 12.04 ( If you need it in Ubuntu 12.04 you can download and install manually using the link –> Force Quit )

So what is the alternative. Use system monitor.

Open System monitor and click Process tab. Locate your application and click “end process” ( This is almost similar to Microsoft windows task manager )
