There's no need to use a while-loop around the call to find.

Also your current approach is very error-prone: it will result in an infinite loop if one of the files is not found, even if the rest of the code worked. Try this instead: 

my %search_for;
$search_for{$_} = 1 for @input_array;
find({ wanted => \&edits}, $dir);
print "Couldn't find these files: ",
      join(', ', keys %search_for), "\n";

sub edits {
   my $file = $_;
   if ($search_for{$file}) {
       print "Found $file, we were looking for it!\n";
       delete $search_for{$file};
       # do the copying etc. here
     }
}
