You can use a schwartzian transform to make it more efficient by only doing the stat call once per file, but other than that there's not that much more to it. Update: For those playing along at home that'd be `@files = map { $_->[0] } sort { $a->[1] <=> $b->[1] } map { [ $_, (stat $_)[9] ] } @files;`	[reply] [d/l]

Well, using a binary heap as a data structure might be more efficient, especially if you know you know that you need only the the knewest `$k` files, then all insertion and deletion operations will be in O(log `$k`) operations. But if you are talking about a more elegant interface: I don't know any :( Perl 6 in German	[reply] [d/l] [select]

Thanks, that may be the way I need to go, but I would rather not reinvent the square wheel if I don't have to. Skip	[reply]
