I have a flat file with a list of element, they are seperated by a new line (\n) and each line is also seperated by a &, example "4&1028x768". The code below works, it searches the file, when it finds a match (1028x768) it increments the count, deletes the original and adds the updated count at the end of the file. What I need to do is, if it doesn't find a match then it will add a new entry at the end of the file, ex. 1&800x600. 
    open (DATA,"$resolution");
    @data = <DATA>;
    close(DATA);

    $data = "@data";

    $data=~ m/.*&$FORM{'res'}\n/i;

    ($count, $res) = split(/&/, $&);

    @add = grep{ !(/.*&$res\n/i) } @data;


    $count++;
    push(@add, "$count&$res\n");

    open (DATA,">$resolution");
    print DATA @add;
    close(DATA);
