How to kill a system process on terminal

Be very careful when killing system process with this procedure, use it only if you really have no other choise:

1- Open Terminal
2- Type: top on the shell
3- Find the number of the process you what to terminate Exp: If you what to kill NortonMiss it will be display like this:

262 NortonMiss 0.0% 0:00.02 1 21 19 68K 540K 436K 27.5M

4- You can't kill this process, is system protected, you need to logon as superuser, to do this, open an other window of the shell and type:

sudo kill 262
(the number of the process is different on each session, and depending on the application or process you what to terminate)

5- You'll be ask for your password, type it and press enter, the app will be kill! (when typing the password, it will not be display on the screen). To cancel the kill press CTRL+Z


NOTES:

Some system process will reboot after they are killed, but this command is usefull if the process hang up, when is rebooted it will work again on most cases.

A superuser have access to all the process and has no restriction on the use of commands on UNIX. Be sure not to reveal the password of your computer to anybody, because if they logon as superuser on your mac, they can deleted any folder.

Use very caution on the use of the "sudo" command.

Well, I only post this as one method, but I know that UNIX is a very flexible OS, so I'm sure there are more ways to kill a process, thanks for sharing them, and...

NifflerX, Thanks! I didn’t know that one, but I also like the top command, 'cause I can see the process activity as I work, useful to know if the process still hang-up or all of the sudden goes back to life like a nosferatu... hehehe. By the way... all that people that just got their macs after a PC with.... agggghhh... Windows XP (sorry I say that)... you will find that the top command is the counterpart of the Process Viewer that shows up by pressing CTRL ALTDEL on the ugly PC keyboard.

Oh.,. And Daniel Macks, you can cancel the command with CTRL+Z when the prompt asks for your password, only at this point.

Thanks for the extra tips everyone!
