kill command format:
kill -Signal pid
pid is the process number, which can be found with the ps command
signal is a signal sent to a process, and TERM (or the number 9) means "unconditional termination"

Here's an example
$  whoami
root
$  ps auxw | grep vi #查询有没有运行vi程序
fenggz 13118  0.0  0.0  4140 1044 pts/1 S+ 05:33 0:00 vi
root    13120  0.0  0.0  4836  640 pts/0 S+ 05:33 0:00 grep vi
#答案: There is a run, process number 13118

$ kill -9 13118 #把vi杀掉 (unconditional termination)

$  ps auxw | grep vi
root    13122  0.0  0.0  4404  640 pts/0 S+ 05:33 0:00 grep vi
#没有vi了...
$

kill command to kill background processes
-9 means forced kill, directly abort
