Hi everybody,

I'm testing a simple IPC implementation that uses Linux pipes to communicate a producer script and a consumer. The producer script looks like:

while(1){
        print "Hello\n";
        sleep(2);
}

And the consumer:

my @lines;
while(1){
        sleep(10);
        if (<STDIN>){#Non-blocking reading
                print "Reading lines...";
                @lines=<STDIN>;
                print "@lines";
        }else{
                print "No lines received.\n";
        }
}

If I run the producer or the consumer alone, there are no problems.

$./producer.pl
Hello
Hello

$echo "Hello" | ./consumer.pl
Hello

[download]

But if I run them together, then de producer does nothing.

$./producer.pl | ./consumer.pl

How can I connect the producer standar output and consumer standar input?

Thanks in advance,

David,
