How do I apply "killall" directive at the shell command line

[JimTrail]

Hello;

I have got the Fedora 7 operating system on a virtual dedicated hosting. I am learning to use the puTTy program.

Someone in this forum was kind enough to help me start the SHOUTcast server. Here's the thread:
http://forums.fedoraforum.org/showthread.php?t=208544

Now I am trying to stop the SHOUTcast sc_serv server program. Someone in the SHOUTcast forum told me to use the "killall" command in order to stop the child processes.

I have typed the following commands at the shell using puTTy:

[user@ip-xx-xx-xx-xx folder]$ killall
[user@ip-xx-xx-xx-xx folder]$ killall sc_serv
[user@ip-xx-xx-xx-xx folder]$ sc_serv killall

None of the commands work.

I have looked over the "Info" file in the puTTy program. There is so much there I don't know where to start looking.

I am a janitor supply salesman. I don't have a whole lot of technical intuition.

Can somebody help me figure out how to get the killall function to work? I would appreciate any help.

Thanks.

Read: man killall

The short version: killall will (as it's name implies) terminate, with extreme prejudice, all instances of the named program that are currently running/open, and for which I have permission to control. For example: if I have six xterm terminals open, and open another xterm and command:
killall xterm

Guess what happens? If, however, one of those terminals is logged on as root user, the killall will be denied/ignored, unless killall is invoked by root user.

The argument is the program name, without any options/flags etc.

P.S. In your case, I'm guessing:
killall shoutcast

Hlingler;

Thanks for responding to my question. I just got it killed. (fortunately I can un-kill it)

You're right. It works like an ax.

Thanks again.

I don't know the first thing about SHOUTcast, but as I understand your post, you are using puTTy to ssh into a Fedora 7 machine that is running the SHOUTcast server, and you want to shut the Shoutcast function down. Assuming that:

[user@ip-xx-xx-xx-xx folder]$

is the prompt in puTTy once you have logged into that F7 machine, it may be that you need root privilges on that remote machine in order to shut the SHOUTcast service down, or just KILL it. Your example shows a normal user prompt "$". You should be able to determine the 'owner', and other info such as the PID, of the SHOUTcast service running by using the command:

ps aux | grep sc_serv

If that returns an entry (or several) then the first item at the left is the owner of the process that is running and the number after that is the PID (Process ID). If the owner is 'root', then you need to become root on the remote machine to shut that process/app down. And knowing the PID, you can use that instead of the app/process name. You can also discover the PID by using the command:

pidof sc_serv

This assumes that "sc_serv" is the correct process name you're trying to kill or query.

edit: Late to the party, as usual, and from the OP's response to Vince's post, looks like misunderstood his intentions.

I usually use kill option with dash 9. It takes fime to follow the PID trail.

kill -9 pid

Look at:

man kill
man killall
