Hi - I'm trying to launch a set number of threads,

Jobs=$Jobs + 1
What shell are you using? In bash, at least, the above won't work -- you
want Jobs=((Jobs+1))
/tibcoresources/appmanage.exe<<lots of params>> &
PID=$!
echo $PID is the process
if [[ $Jobs -gt 2 ]]
then
{
echo pausing
wait $PID
Jobs=0
echo starting
}
fi
But - I don't get anything back from $!
so the wait doesn't wait and I end up
launching a bunch of processes and taking
down the server, etc, etc, etc.
Just to be sure, you've confirmed that the problem arises because the
if-then body runs with an empty $PID? Do the two echo commands fire?
