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

🚀 CPI Faces Critical Test Amid Inflation Concerns The upcoming Consumer Price Index (CPI) report is set to be a decisive factor in assessing inflation trends, as consensus builds around a significant rebound in inflation. According to Jin10, the breadth of the energy shock will play a crucial role in determining the intensity of market impacts. The ongoing conflict between the U.S. and Iran has influenced the CPI statistics for March, with energy premiums potentially limiting the Federal Reserve's ability to cut interest rates. There is a risk that inflation expectations may become unanchored, raising questions about whether price pressures are a one-time shock or have spread to other sectors. #CPI#Inflation#EnergyShock#FederalReserve#InterestRates#USIranConflict#MarketImpact#PricePressure

🚀 Expert Predicts U.S.-Iran Conflict Impact on Crypto Markets Until 2026 Nic Puckrin has expressed concerns that the ongoing U.S.-Iran conflict could negatively affect cryptocurrency markets until 2026. According to NS3.AI, Puckrin believes that Bitcoin's recovery to $90,000 would require several favorable conditions. He also noted that a Federal Reserve rate cut is unlikely to occur before late Q3 or Q4, and it may not happen at all this year. #USIranConflict#CryptoMarkets#Bitcoin#Cryptocurrency#FederalReserve#MarketPrediction#2026Impact#BitcoinRecovery#BTC
