Killing/Ending a process
 

What is the difference between killing and ending a process?
Which is advised?

Lets say I ran p0f. After say 1 hour, I want it to stop running cos I already have the necessary data that I want. I know that p0f will appear in the system monitro under bash->shell->p0f. By right clicking, I can kill it because I know that it is p0f.
But, how can I kill this process using the shell prompt?
I have read the man but still unsure. I have tried some parameters and all but to no avail.

Thanks

# kill PID
where PID is the process ID# which can be found by typing: ps ax

Similarly, you can run: top which lists the processes that are consuming the most resources. Either way, the kill command will stop it (you may need to be root to kill it) -- J.W.

Another option to kill prosseses from the command line is killall. It operates in a simalar way to kill, though it also allows you to use the name of the prosses instead of merely the PID. For example, you want to kill httpd (apache), you would type:
killall httpd
it can also be used to send other signals, such as the HUP (hangup) signal through killall -HUP, that often restarts programs that function as servers, or killall -9, which tells the program to die imedately.

Using killall
 

First I ran p0f at prompt, OK.
THen I stopped it, using ctrl-C.

I want to kill this process by its name and not its PID.
Using ps aux I see p0f is still running even though I had stopped it
I tried using killall p0f and killall -15 p0f but still when I run ps aux, it is still there.

How can I solve this?
