Шпаргалка GDB

Question

Кто-нибудь может порекомендовать хорошую шпаргалку для gbd? У меня есть опыт работы с командами windbg, я ищу эквиваленты GDB для lml (список загруженных модулей), ~ * k (стек всех потоков), ba (прерывание при доступе), dt (тип дампа), dv (переменные дампа) ), sxe (настроить обработчик SEH) и т. д. Я понимаю, что не будет эквивалента от 1 до 1, но мне просто нужна краткая сводка наиболее используемых / используемых команд.

Answer 1

Я использую это лично: шпаргалка GDB или эта ссылка еще не сломана .. . Я напечатал это на работе.
