День добрый!

Каким образом можно получить код возврата при выполнении внешнего приложения? Т.е. я вызываю программу из скрипта на perl, но мне нужен не вывод это программы (@result=`date`), а именно тот код возврата который устанавливает внешенее приложени при выходе. Т.е. то же самое, что в shell дает $?.

Смотрим "perldoc perlfunc", функция system():
