reload_flag="" if [[ -n "${DEBUG}" ]]; then reload_flag="--reload" fi if [[ -n "${WORKER_COUNT}" ]]; then workers=${WORKER_COUNT} else workers=2 fi gunicorn --workers ${workers} \ --bind 0.0.0.0:8000 \ ${reload_flag} main.wsgi Писали такие конструкции чтобы проверить наличие флага и сформировать команду правильно? На самом деле можно сделать тоже самое проще. Для этого используются операторы условной подстановки, доступные в оболочках семейства POSIX. :- для установки значений по умолчанию ${WORKER_COUNT:-2} Если переменная не объявлена, то будет дефолтное значение 2. :+ подставляет указанный текст, если переменная не пуста ${DEBUG:+--reload} Если что-то есть в переменной то распечатается текст после символа +, в противном случае - ничего. Удобно для опциональных флагов, как в нашем примере. Итого наш скрипт может выглядеть так: gunicorn --workers ${WORKER_COUNT:-2} \ --bind 0.0.0.0:8000 \ ${DEBUG:+--reload} main.wsgi Есть еще два оператора. := не только подставить дефолтное значение, но и присвоить его переменной, если она пуста # никаких переменных еще нет VAL1=${VAL2:=hello} # теперь доступны обе echo $VAL1 $VAL2 # hello hello :? остановить выполнение с ошибкой, если переменной нет. echo ${MISS:?is required} bash: MISS: is required Код выхода будет 1. #tricks#linux

Pump Leaks

@pumpleaks · Post #678 · 06.01.2024 г., 00:36

Pump Result: One of the best pumps we’ve had. The volume crossed an unprecedented $3.2 million in the first 15 minutes, catapulting #LAYER to our 10x target (957%) and making all of our members huge profits, that’s exactly why we’re the best in the world. Our coin held as the top gainers for hours after our signal, demonstrating the real power of our whales and market makers. Even though we saw a huge volume of external selling (very likely coming from the coin team), we truly delivered on the expected exceptional first pump of the year, and things are just going to get better from here. We’re still receiving an overwhelming amount of gratitude messages from members that scored big, and asking for our next pump. No stress, enjoy the profits, we’ll announce it soon. In the meantime, we’re focusing our efforts on never used before marketing strategies to bring in over 1 million new members for our next Kucoin Mega Pump, which will absolutely dwarf anything we’ve seen until now. Stay tuned for our next pump announcement.
