Gah..! really? fork 4 processes to get a list of files excluding a pattern?

{
    my $dir = './logs';
    opendir my $dh, $dir or die "Can't opendir '$dir': $!\n";
    my @files = grep { ! -d "$dir/$_" and ! /file1/ } readdir $dh;
    print "$_\n" for @files;
}
__END__

To me, integrating doesn't mean copy & paste, but also throwing out cruft and rewrite. The shell command is poor to start with - useless use of grep... then your $9 in the awk command isn't portable, there are different date formats around, e.g. 2007-05-22.
