Is there an easier way to remove duplicate words ie. "I love love this" from a text file? 
 
my ($File, $Line, $Contents, @Lines, $i, $j);

$i = 0;
$j = 1;

$File = "P:\\K\\kmartin\\set1.txt";

# Open file and put it into one long line
open (FH, "<$File");
while (defined($Line=<FH>))
{
    chomp $Line;
    $Contents .= $Line;
}
close (FH);

# Puts words into an array
@Lines = split /\W+/, $Contents;


while (<@Lines>)
{
    
    #compare contents on array cell
    if ($Lines[$i] eq $Lines[$j])
    {
        print "Duplicate word: $Lines[$i]\n";
        $i++;
        $j++;
    }
    
    #If not equal, increment counters
    else
    { 
        $i++;
        $j++;
    }
}
