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

Memorial park honoring prominent #Somali anti-colonial leader Sayyid Mohammed Abdullah Hassan inaugurated in #Jigjiga A new memorial park honoring Sayyid Mohammed Abdullah Hassan, the early 20th century Somali scholar, poet and anti-colonial military leader, has been officially inaugurated in Jigjiga, capital of #Ethiopia’s Somali Regional State. Known in Somali as Maxamed Cabdulle Xasan, Sayyid Mohammed Abdullah Hassan is know to have founded and led the Dervish movement, which waged armed resistance against #British, #Italian and Ethiopian colonial expansion in the Somali Peninsula. While widely revered by many Somalis as a symbol of anti-colonial struggle, he was pejoratively labeled the “Mad Mullah” by the British Empire. In 1917, the Ottoman Empire recognized him as the “Emir of the Somali People.” Regional President Mustafa Muhummed presided over the ribbon-..... https://web.facebook.com/AddisstandardEng/posts/pfbid035zhG5D71mJR7UdFHybuQqaDPAcU8msaQNqQShDRQ5NYGVkbYXYFHbQGW62n97vmrl
