This wouldn't work, because he's trying to delete files using globbing. 
The following would work:

    my $oldfiles = 'foo.*';
    unlink < $oldfiles >;

As would:

    use File::Glob qw(:glob);

    my $oldfiles = 'foo.*';
    unlink glob($oldfiles);

The first one gives a warning for some reason (haven't looked into why), but the second doesn't.

As for why the code isn't working, does it have something to do with mixing up shell variables and perl variables?

Doing the following in Perl:

    unlink glob($oldfile) or warn "Can't delete '$oldfile': $!\n";

and the following on the command line:

    rm ../html/wrt_archive/weekly_archive/*to$twodaysback*.*

What exactly is the $twodaysback variable, and where is it coming from?

Although on second thought, if this isn't set in Perl, you'd just be doing:

    rm ../html/wrt_archive/weekly_archive/*to*.*

which should work. Trying doing:

    system "ls ../html/wrt_archive/weekly_archive/";

to make sure you're in the right directory, and see what you get.
