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

Mexc Crypto Signals Pumps Trading Kucoin

Hello everyone! 24 hours left until our next Kucoin pump. The market looks very good and our power is growing every day. We expect a massive volume and profits tomorrow. This is a brief explanation of what will happen during our pump: 1) When the coin is announced, we buy it together, as a team. 2) This initial push triggers buying from trading algos, MM bots and generally – outsiders. 3) As the outsider buy orders further increase the price, we begin to slowly sell way higher than where we bought. Full guide can be found in the previous messages. Here are the results of our latest pumps: #HIP → 2400% #QUICK → 1500% #BONDLY → 800% #FEAR → 750% #VEMP → 750% IMPORTANT: We are the original and longest running pump group. Please ignore all ads in this channel as they are not approved by us, we do not endorse any other channels. All other alleged "pump" groups are copycats trying to capitalize on our success, reputation and care for members.
