I've a program which opens a system command which never finishes. Currently, I just: 
open CMD, "/usr/local/bin/inotifywait |";

while (my $output = <CMD>) {
.......
}

Rather than block for the output, I would like to start the command and spool the output to an array. Simultaneously, I would then parse the output if certain conditions exist (system load, time of day). How could I do this? Could fork be used? 
my @output;
while (my $line = <CMD>) {
        chomp $line;
        push @output, $line;
}

Then somewhere else... 
for my $out (@output) {
        if (condition exists) {
                parse output;
        }
        .....
}
