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

🇳🇴 NORWAY PHASES OUT UNNATURALLY FAST-GROWING “FRANKEN-CHICKENS” Norway has announced a gradual phase-out of so-called “franken-chickens” by 2027. Norway, where about 70 million chickens are raised annually for food production, has become the first country to commit to raising 100% of its poultry under conditions that ensure high animal welfare standards. Animal rights advocates have welcomed the decision, calling it a “historic moment.” “Franken-chickens,” often referred to in Norway as “turbo-chickens,” are fast-growing birds bred through selective breeding to reach maximum weight in the shortest possible time. Due to rapid growth and extreme size, these chickens suffer from numerous health problems, and most animal welfare organizations strongly condemn this practice. According to Humane World for Animals, franken-chickens reach their “slaughter weight” in just six weeks, leading to severe strain on their bones, muscles, and ligaments. Their bodies often begin to break down as they grow, and many birds lose the ability to move. Humane League UK describes their lives as “extremely short and painful.” The animal protection coalition Anima International has been campaigning for five years to eliminate fast-growing chicken breeds in Norway. Several animal welfare groups are also calling for similar measures in the United Kingdom. Experts emphasize that this decision marks a significant step forward in improving animal welfare. #AnimalRights#Norway#AnimalWelfare#PoultryFarming#ProtectAnimals ☘️Read the latest environmental news on the @ekologuz page.

🐾 Where are the dogs disappearing in Yangiyul? At the temporary dog holding center (shelter) in Yangiyul, on February 10, volunteers recorded the dogs in the shelter. According to the volunteers, almost no adult dogs remained — all of them were reportedly killed overnight. A day earlier, many dogs were in the shelter, but when the volunteers visited, they saw only 5–6 dogs in the cages. The question is: where did the rest of the dogs go? Volunteers say they were killed. According to the volunteers, tomorrow the remaining poor dogs on Persidskaya Street — who are already afraid of every little sound — are also scheduled to be killed. 💔 This is not just statistics. This is a matter of our humanity. #ProtectAnimals#Yangiyul#AgainstCruelty#Ethics#Animals ☘️Read the latest environmental news on the @ekologuz page.
