=item unlink

Deletes a list of files.  Returns the number of files successfully
deleted.

    $cnt = unlink 'a', 'b', 'c';
    unlink @goners;
    unlink <*.bak>;

Note: C<unlink> will not attempt to delete directories unless you are superuser
and the B<-U> flag is supplied to Perl.  Even if these conditions are
met, be warned that unlinking a directory can inflict damage on your
filesystem.  Finally, using C<unlink> on directories is not supported on 
many operating systems.  Use C<rmdir> instead.

If LIST is omitted, uses C<$_>.
