Explanation:
kill -9
Kill (terminates without cleanup)
Only works if issued by process owner or super user (root)
The program cannot respond to this signal; it must terminate
Note: Unix provides security mechanisms to prevent unauthorized users from killing other
processes. Essentially, for a process to send a signal to another, the owner of the signaling
process must be the same as the owner of the receiving process or be the superuser.
