Hello oxalate,

Here is a tip regarding this section of the code:

foreach my $i (@array)      
        {
        if(grep @array[$i], @files)
            {
            my $match = (grep @array[$i], @files);

First of all, $i is being set to the actual filename, not your array index. Thats why nothing seems to be working properly. Try this to see what I mean:

$ perl -we '
my @array = qw( file1 file2 file3 );
foreach my $i (@array) {
    print "\$i = $i\n"
}'
$i = file1
$i = file2
$i = file3

If you want $i to contain the array index, you could use $#array which will give you the number of array elements minus one (the highest index) along with the range operator:

$ perl -we '
my @array = qw( file1 file2 file3 );
foreach my $i ( 0 .. $#array ) {
    print "\$i = $i\n"
}'
$i = 0
$i = 1
$i = 2

Also, if you want to index into an array you should do it like this: $array[0]. Not like you have it, @array[0]. The way you have written it, you are taking a slice.

This might get you a little bit closer to what you are trying to do...

Best,

Jim
