I think the problem is in your section of:
for(@array){
($i)= grep { m/^#/ } $_;
push @new, $i;
}
What about replacing that with:
foreach my $line (@array) {
next if ($line =~ /^#/);
push @new, $line;
}
Mine might be a bit less compact, but it is much more readable and easier to see what it happening there.
Also it appears to me that when you are writing back to your file, you are putting in 4 extra linebreaks. Is that intentional?
