OK. Thank you for your thoughts.

Before I try your experiment, I commented out the following lines from your script:

Code:

for agent in "$@"
do
  ./run-any-agent $agent &   # run in background
done

I guess it didn't do anything...

Next, I restarted my machine and ran the "run-all-agents" script like this:

Code:

sh ./run-all-agents MyProgram1 MyProgram2 MyProgram3

Then, I went through all the processes using the following command:

Code:

ps aux | more

And killed the three processes, I'd spawned using the "kill -9" command. They died. However, this process doesn't seem to die (despite repeated attempts to kill it):

Code:

DTW    13986  0.1  1.0 1196768 21528 pts/0   Sl   14:21   0:00 java -server -Xmx1024M -Xms512M -cp ....

Now, I'll try restarting the machine and then try your experiment and report back.

Thanks,

DTW

Code:

#!/bin/bash
#
# Usage
# From the agent directory:
# ./run-all-agents AgentName1 AgentName2 ...
#
trap killsubs INT
killsubs()
{
  echo "CTRL-C was pressed"
  jobs -p|xargs kill
  echo "Jobs were killed"
  exit
}

TAC_AGENT_HOME=`pwd`
LIB=${TAC_AGENT_HOME}/lib
CLASSPATH=.
CLASSPATH=${CLASSPATH}:${TAC_AGENT_HOME}/bin
for i in $( ls ${LIB}/*.jar ); do
  CLASSPATH=${CLASSPATH}:$i
done

for i in "$@"
do
  java -server -Xmx1024M -Xms512M -cp $CLASSPATH edu.umich.eecs.tac.aa.agentware.Main -config "config/$i.conf" &
done
wait

So, I did what you suggested and called the above script, "test-script1". I ran it like this:

Code:

 sh ./test-script1 MyProgram1 MyProgram2 MyProgram3

It started up. Then, when I hit "Ctrl+C" it stopped. Everything stopped nicely. I even did a "ps aux | more" command and looked at the running processes carefully but there was no sign of either of the three programs running. Also, there was no sign of the "java server" running - for the first time. :-) I can test this out and see if the programs are actually functional and report back. Does that sound fair?

Hi!
I'm back. I did try to run the programs too and they ran just fine. I tried stopping/starting the programs and they did so every single time. I'm so happy that this is finally working! Thank you very much for all your help, Scrutinizer.

I do have one more question, though. Before I start the programs, I fire up a server using the following script:

Code:

#!/bin/bash
#
# Usage
#   sh ./runServer.sh
#

TACAA_HOME=`pwd`
LIB=${TACAA_HOME}/lib
CLASSPATH=.
for i in $( ls ${LIB}/*.jar ); do
    CLASSPATH=${CLASSPATH}:$i
done


java -cp $CLASSPATH se.sics.tasim.sim.Main

So far, I've been able to "kill" the server by just hitting Ctrl+C. However, this doesn't always work. Is there a way to nicely kill this process too? That way, we'd have a script to nicely start/stop the server and then another one to nicely start/stop the programs.

My next goal (after the server start/stop script is implemented and tested) is to truly understand what we did so that I actually learn some scripting too. :-)

Sincerely,

DTW
