Опции bash для разработки

Разрабатывайте скрипты с опциями set -eu

• set -e - падать на ошибках
• set -u - считать ошибкой обращение к неопределенной переменной

Профиты

• максимально быстрое выявление скрытых ошибок в коде.
• не надо самому писать многие проверки значений.
• Это сделает shell-код похожим на нормальный язык программирования, а не на набор последовательно выполняющихся команд, которым на всё пофиг.
