Tell your wanted sub to ignore files whose name starts with a period:

sub wanted {
    return if /^\./;
    ...
[download]

This is more stringent than you asked for. If you want to specifically exclude only the "." entry, change the expression to:

    return if /^\.$/;
[download]

HTH

Update
arturo correctly points out there's no reason to use a regex to test a simple string equality. The second one should be:     return if $_ eq '.';Thanks, arturo!
