Sure, but it's a little tricky. You would first need to find out the PID of the agent you started. You could do this with the 'ps' command.
Thanks for your reply. Cool. So far I've been doing:
Code:
ps aux | more

And then I scroll through the list to find the PIDs. Sometimes when I use the "kill -9" command, though, it doesn't seem to kill the process. I'm not sure why.
Code:
% ps -ef | grep "run-any-agent MyProgramN " | grep -v grep

  userid 13112 13110  4 15:10:03  ttyp12    00:00:00 run-any-agent MyProgramN

I'm not sure what "-ef" and "-v" do but I can look them up.

The PID in the above example is 13112. The tricky part is you don't want to leave any child/zombie processes that may have spawned from your script. If it does spawn extra processes then your script will have to find all the children and kill them in order. The last process you would kill would be 13112 since that is your original process. It's definitely doable though. Hope that makes sense.
Yes, it makes a lot of sense. My next question then would be: How do I find out all the children or zombie processes and then go ahead killing them nicely? This way, then I'd have a neat way (thanks to you) to start the programs and then another neat way to kill them all. It would save me a lot hassle. I must say that scripts are cool. :-)

Thanks,

P.S:

NOTE: Notice that I left a space after MyProgramN in my grep statement. This was done to ensure you had the right process for those cases when you might have MyProgram1 and MyProgram11 running. If you're looking for MyProgram1, then you want to make sure you don't accidentally catch MyProgram1N.
Hmm - I'd have to think about what you wrote, but, thank you for clearing that up.

So, I tried:
Code:
ps -ef | grep "run-any-agent MyProgram1 MyProgram2 MyProgram3 " | grep -v grep

After I typed:
Code:
./run-all-agents MyProgram1 MyProgram2 MyProgram3

But nothing happened...Did I miss something?

So, "-e" seems to be a way to use a pattern of some sort. I'm not sure what the "f" after the "e" does, really.
"-v" specifies the string that we don't want to grep.
Code:
grep abc -v

would mean look for all files that DON'T have "abc" in them? Does this sound correct?
