I need to run a single command on multiple boxes.  I am pulling the cpu name from an array then plugging them into a loop.  I am then forking the loop so that all of them run at once.<o:p></o:p>

The problem that I am experiencing is: Is there a way to control the number of sessions made at once by the looped fork?  <o:p></o:p>

If I am running the command on 20 servers I am OK.  However, if I need to run it on all 2000 of the boxes, then I run into MAJOR system resource problems.  As a temprary fix I am forking 20 of them, then running 1 outside of the fork. When the 1 from outside of the fork ends then the whole process starts over.  This allows me to do them in CHUNKS of 20.  What I am looking for is a way that allows a new session to start whenever one ends, so that I have a CONSTANT streem of 25 sessions NOT chunks of 25.<o:p></o:p>


##this runs the entire list at once

@list=(1,2,3);                #list

while(<@list>){              #I loop the list    
        
    if (fork){          #with the loop I run the whole list at once
        
        print "$_\n";     #I do my stuff

    exit;
    }
}
