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

The custom of putting candles on cakes dates back to the ancient Greeks, who honored the goddess Artemis by placing lit candles on round, moon-shaped cakes. They believed that the smoke from the candles carried their wishes and prayers up to the gods in the sky. @googlefactss#history#ancientgreece

The name Ethiopia comes from the ancient Greek word “Aithiopia.” It comes from “aithō” (to burn) and “ops” (face), meaning “burnt face.” Ancient Greeks used this word to describe dark-skinned people living south of Egypt. The word appears in the works of Homer, who lived around the 8th century BCE. 🌍🔥 #Ethiopia#History#AncientGreece#DidYouKnow@googlefactss

In ancient Athens, some elite men formed socially recognized relationships with adolescent boys called eromenos. The adult, erastes, acted as a mentor, teaching the boy skills and introducing him to society. These relationships were accepted at the time and had strict social rules: the boy had to be young and not fully grown. Once he reached adulthood, remaining in that role was considered inappropriate.. 🏛️📜 @googlefactss#AncientGreece#History#Athens#Culture#Mentorship#Elite#law
