The one catch, as I alluded to in my respose to Frodo, is that there is the possibility of a "false" match (i.e. a match in two of the files, but not all three), hence even if the first two processes on the pipeline find a match, I can't guarantee it wil be repeated with the third process.

My problems up until this point have really centered around this one fact, returning control to a process earlier on the pipeline and repeating the cycle of: if(match)then pass on to next process... this is complicated by the fact that the Eclipse/EPIC debugger craps out on me when I try and step through the code of any one of these processes (with the other two running in the background) and I can't seem to get my STDOUT print statements to work reliably once I've opened a socket for writing.

Can anyone give me an example of how to use a single socket in a bidirectional manner?

For instance, if I set a socket up to receive: 

my $s_socket = IO::Socket::INET->
new('LocalPort' => $S_PORT,
    'Proto' => 'tcp',
    'Listen' => 2)
or die "Third: Can't create socket to Second($!)\n";

while (my $second = $s_socket->accept) {...}

but then later on need to send over that same socket: 

while(<$second>)
{

if($_ eq $match) {    
    print $s_socket "$match\n";
    scalar <$s_socket>;
            
    last;
}

}

Am I doing this in the correct manner - what steps am I forgetting? In a nutshell the statement above (both sending and on the receiving process end) is what has been giving me the most headache.

Any help would be much appreciated!
