Hi monks need some help here, My code checks a temp.txt file and find a string like; 
<17>11,2002,FORD    ,ECONO CO,        ,34567676xxxxx   
<17>11,2002,FORD    ,ECONO CO,        ,34567676xxxxx

My problem is, it's finding what I am looking for but I want to make sure even if there is duplicated strings I print only one time, and my code is printing multiple times. How could I do that in my code and not allowing to print duplications of the found match.
Thank you!!!
<br>
$temp_file = "${curr_dir}work/$AoH{20}_p22.txt";

open(TEMP, "$temp_file") || print "Can't open temp file: $temp_file\n"
+;
while(<TEMP>) {
    $_=~/<(.*?)>(.*)/;
    
    unless ($2 eq "*") {
    unless ($1 eq "20") {
        if ($1 eq "17") {
        my $hold=$2;
        $hold=~/^(\d\d),(.*?),(.*?),(.*?),(.*)/;
        $AoH{10}= $AoH{10}."<option value=\"$1\">$2,$3,$4 \n"; }
        else {
        $AoH{$1}=$2;}
    }
    }
}
close TEMP;
