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

🚀 Federal Judge Halts Arizona's Arraignment of Kalshi Over Prediction Market Contracts A federal judge has issued a temporary restraining order preventing Arizona from proceeding with the arraignment of Kalshi on 20 criminal charges related to its prediction market contracts. According to NS3.AI, District Judge Michael Liburdi ruled that Arizona cannot conduct Kalshi's arraignment scheduled for Monday, April 13. The order prohibits Arizona from applying its gambling laws to contracts listed on designated contract markets regulated by the Commodity Futures Trading Commission (CFTC). The CFTC, which has filed a lawsuit against Arizona and two other states, contends that these event contracts are considered swaps under federal oversight. #FederalJudge#Arizona#Kalshi#PredictionMarket#Contracts#TemporaryRestrainingOrder#GamblingLaws#CommodityFuturesTradingCommission#CFTC#Lawsuit#Swaps

🚀 Federal Agencies Challenge Arizona's Gambling Laws Against Kalshi The Commodity Futures Trading Commission (CFTC) and the Department of Justice have requested a federal court to prevent Arizona from applying its gambling laws to Kalshi. According to NS3.AI, the agencies argue that contracts related to sports and elections are federally regulated swaps. Arizona has initiated criminal charges against Kalshi, with an arraignment set for April 13. Should the courts agree with the federal perspective, prediction markets could potentially function across the United States under a unified federal framework, rather than being subject to individual state gambling regulations. #FederalAgencies#Arizona#GamblingLaws#Kalshi#CFTC#DepartmentOfJustice#FederalCourt#SportsContracts#ElectionContracts#PredictionMarkets#FederalRegulation#StateGamblingRegulations
