I have quite a large log file that I'm parsing and the script I have is very rough. With that aside, memory management is not something I have worked with before, and when this script is run I do run out of memory. What would be the most efficient way to parse through a 400mb file? Please excuse the dirty code: 
while(<>){    
    if ($_=~"Sent:"){
        $count += 1;
        push (@dates, $_);
            }
    if ($count < 1){
    if ($_=~"Per Domain Breakdown"){
        until ($_=~"From:"){push (@list, $_);}
        push (@list, "BREAK $count");
        }
    }
}

print @dates;
print @list[1];

The count was added only to test the first 1000 pieces or so of data. As to that, the data was not even being pushed into @list. Any help would be great. Thanks! ~Phantom **UPDATE** What I was attempting now works with this code: 
while(<>){    
    if (/^[0-9]+, |Sent:/){
        push (@logs, $_);
    }
}

print $logs[0];
print $logs[1];

As Funkymonk and TGI pointed out I misunderstood my program, and the until hurt it. Thanks for all the help! ~Phantom
