I have a feeling this is either going to be easy or impossible.

I need to:
-read a dir
-find the ten newest files in it
-delete any others

I'm relatively sure that what I have below will remove anything older than 10 days, but I need to keep *10 days worth* of files. (Since this'll be run by cron daily, I have a problem on weekends or any other day when nothing is added to the directory..I fall below my mark of retaining the 10 *most recent* files.) 

#!/usr/local/bin/perl -w

use strict;
use vars qw($archivedir @subdirs $subdirs);

$archivedir = "/web/1/someplace" ;

# READ CONTENTS OF DIRECTORY AND DELETE FILES OLDER THAN 10 DAYS
opendir (ARCHDIR, "$archivedir") || die "Couldn't access the directory
+!";
    @subdirs = readdir(ARCHDIR);
    foreach $subdirs (@subdirs) {
        if (-M "$subdirs" > 10) {
          rmdir("$archivedir/$subdirs");
           }    
    }
closedir ARCHDIR;

Ideas? Feel free to berate me if this turns out to be easy or my code looks silly. I'm still have tons to learn and welcome *any* advice.

Thanks!
