I have a script that allows users to add information to a flat file db. The information added by users is kept on the file for 14 days. After the expiration time has been reached the data is removed. The removal process only occurs when new data information is added to the file. Is there a way to remove the expired data when the script is run as well as when data is added? Here's the code that removes expired data when new data is added: 
    open(DATAFILEIN, "$catagory.dat") || print "Your listing is the fi
+rst in this category!<br>";
    flock (DATAFILEIN, 2);
    while(<DATAFILEIN>) {
        @line_pair = split(/=/,$_);
        $time2 = $line_pair[6];
        $currenttime = time ();
        $difference = $currenttime - $time2;
        #computing the number of seconds before it expires
        $expires = $expire_after_days * 86400;
        if($difference < $expires){
            push (@temp,$_);
        }
        
    }
    flock (DATAFILEIN, 8);
    if (open(DATAFILEOUT, ">$catagory.dat") ) {
        flock (DATAFILEOUT, 2);
        print DATAFILEOUT "$time=$company_name=$email=$member1=$member
+1phone=$data=$expiretime=$pictureurl=$password=$website=$member2=$mem
+ber2phone=$address=$citystatezip=$fax=$catlisting\n";
        print DATAFILEOUT @temp;
        userlog();

And here is the db viewing code that I'm trying to adjust to have expired information removed. I've attempted using the above script but only manage to remove all entries. 
            open(DATAFILEIN,"$catagory.dat") || print "This section is
+ currently empty...Please check back often!";
            print "<table border=0 cellpadding=0 border=0>";

            while (<DATAFILEIN>) {
                chomp $_;
                @line_pair = split(/=/,$_);
                $company_name = $line_pair[1];
                $time = $line_pair[0];
                $email= $line_pair[2];
                $member1= $line_pair[3];
                $member1phone= $line_pair[4];
                $data= $line_pair[5];
                $time2 = $line_pair[6];
                $data = &stripBadHtml($data);
                $password= $line_pair[8];
                $pictureurl= $line_pair[7];
                $website= $line_pair[9];
                $member2= $line_pair[10];
                $member2phone= $line_pair[11];
                $address= $line_pair[12];
                $citystatezip= $line_pair[13];
                $fax= $line_pair[14];
                $catlisting= $line_pair[15];

Anyone have any suggestions? Thanks!! Lis
