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

UN chief warns of "immense suffering" as Gaza aid remains inadequate. Israel's relentless bombardment overwhelms hospitals and leaves Gaza without essential supplies. More than 8,500 lives, including children, have been lost. The situation is "absolutely horrific", says Red Crescent. Calls for a ceasefire and increased humanitarian aid are rejected by the US, prioritizing their support for Israel. As the death toll rises, the UN pleads for an end to this "spiral of death". The world must act now to prevent further tragedy. #GazaCrisis#HumanitarianAid https://www.aljazeera.com/news/2023/10/31/un-chief-guterres-says-aid-trickling-into-gaza-is-completely Subscribe to @BadVolfNews
