This kind of question is something that chatter is useful for. After all if you don't use it regularly, there is no way that you would ever think of something like:
foreach my $file (glob("$dir/*")) {
next if -M $file < 2;
# Do something with this old file
}
But after you have seen it a few times, you have a much better idea what to look for.
But if you are going to use chatter, I strongly recommend trying to figure out the smallest thing that you need to know which is helpful. For instance, How do I found out how old a file is in Perl? Otherwise you will get a lot of answers that don't address your real problem. Which is frustrating all around. You don't like it because it isn't useful. Whoever is trying to help doesn't like it because their effort isn't going anywhere...
