Code: (dl )

if (($daily && $weekly) || ($daily && $monthly) || ($weekly && $monthly)) { usage() }

sollte funktionieren. Oder du verwendest einen Hash:

Code: (dl )

1
2

GetOptions("daily" => \$p{daily}, "weekly" => \$p{weekly}, "monthly" => \$p{monthly}, ...);
if (1 != grep $_, values %p) { usage() }

if (1 != grep { defined } ($daily, $weekly, $monthly)) {
    usage();
}
