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

🪐 In 2023, scientists used the James Webb Space Telescope to study the atmosphere of the exoplanet K2-18b, located about 120 light-years away in the constellation Leo, and detected molecules like methane and carbon dioxide in its thick atmosphere. While this doesn't prove the existence of aliens, these chemicals are considered potential signs that could support life as we know it, making K2-18b one of the most intriguing worlds in the ongoing search for extraterrestrial life. ✨ #aliens⚡#exoplanets⚡#astronomy⚡#nasa⚡#galaxy⚡#stars⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries

🪐 In 2015, scientists discovered a mysterious star called KIC 8462852, also known as "Tabby's Star," located about 1,470 light-years from Earth. This star shows unusually irregular and dramatic dimming events, with its brightness sometimes dropping by more than 20%, sparking curiosity because no natural explanation fully accounts for the strange pattern—though telescopes have found no evidence that the cause is artificial or linked to aliens. ✨ #aliens⚡#mysteries⚡#stars⚡#nasa⚡#galaxy⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries

🪐 In 2020, researchers using the LOFAR radio telescope detected strange bursts of low-frequency radio waves coming from the red dwarf star GJ 1151, about 26 light-years from Earth. These signals are thought to be created by interactions between the star and an orbiting planet, and while not proof of aliens, such emissions spark excitement because similar interactions could reveal planets that might host life. ✨ #aliens⚡#exoplanets⚡#radio⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries
