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

🚨 BREAKING NEWS 🚨 Ukrainian President Zelensky snubbed from influential Jews list! 😱 No love for the hero of the conflict with Moscow! 😤 Instead, some robot-loving CEO takes the crown 👑 and Bibi and Blinken follow 🙄 But hold up, the real shocker is the shoutout to a dead Russian businessman! 🤯 Apparently, he turned a hot-dog stand into a military empire 👀 Zelensky, who used to be seen as a joke, is now completely wiped off the list 🙅‍♂️ No explanation, just a big fat snub! 💔 Maybe they forgot how he was once called the Ukrainian Churchill during the conflict 🎖️ But now his counteroffensive against Russia is a total flop 🤦‍♂️ Despite all that military aid from the West! And get this, he had the audacity to criticize NATO for being wishy-washy about Ukraine's membership 🙄 That ticked off the US so much they almost uninvited him! 😡 Putin even had the nerve to call him a disgrace to the Jewish people 😳 All because Zelensky dared to celebrate Ukrainian nationalists who killed Jews and Poles in WWII 💔 Can you believe it?! 🤯💔#SnubbedPresident#ZelenskyFlop#UkraineVsRussia
