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

🚜First farming pool from Tomarket While we are all waiting for the $TOMA listing and watching the price on the TOMA/USDT premarket, the team launched a farming pool with its first partner — DuckChain. About farming $DUCK Points By staking $TOMA in the Farming Pool, you will secure a spot in the TGE #DuckChain airdrop and will farm $DUCK Points faster than through their mini-app. Not Bad. 🥚 Collect eggs in DuckChain. After staking, head to DuckChain to start farming eggs — these eggs are rare and valuable, so don't miss your chance. 🍅Stake TOMA in the Tomarket farming pool. Once staked, join DuckChain to collect eggs: ✅Join the DuckChain app ✅Subscribe to DuckChain channel ✅Subscribe to DuckChain on X ⚠️Note: If you have trouble with TOMA distribution, don't worry — there will be plenty of time to join after the team completes the review. Rewards will not be affected by whether you enter the pool early or late. 🧐Does it worth to participate? This is probably just the beginning of the project's journey towards onboarding in #GameFi and #memecoins. If the #Tomarket team is really interested in playing for the long term, they should thank early adopters, for their support — give a fat drop to the first pool. If the community does not support the project, this will probably be the end of it. And our $TOMA will be worth nothing. So it's up to you to decide. #fun#belong#money Farming pool DuckChain 🦆
