kill

KILL (Resource kit)

Remove a running process from memory.

Syntax KILL [option] process_id KILL [option] task_name KILL [option] window_title Option -f Force process kill

Note: Kill -f basically just nukes the process from existence, potentially leaking a lot of memory and losing any data that the process hadn't committed to disk yet. It is there for worst case scenarios - when you absolutely must end the process now, and don't care whether proper cleanup gets done or not.

In WindowsXP, KILL is replaced with the superior TASKKILL - Allowing you to specify a remote computer, different user account etc - for more details run TASKKILL /?

If you're going to tell people the truth, you'd better make them laugh. Otherwise they'll kill you. - George Bernard Shaw
