Here is a simple example: 
pipe(my $reader, my $writer);    # Create a pipe

if (my $pid = fork()) {
    # In parent: read one line from the pipe and print it
    print "Message from child: ".<$reader>;
}
else {
    # In child: print a line of text to the pipe
    print $writer ("Hello, parent!\n");
}
