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

🚀 Bitcoin and Ethereum Futures Open Interest Surge Amid Improved Macro Sentiment Bitcoin and Ethereum perpetual futures have seen a significant increase in open interest, rising by $2.1 billion and $2.2 billion respectively over the past 24 hours.

🚀 Bitcoin Futures Open Interest Hits 14-Month Low Amid Institutional Strategy Shift On April 11, the open interest in Chicago Mercantile Exchange (CME) Bitcoin futures fell to $8.41 billion, marking its lowest level in 14 months. According to BlockBeats, Glassnode analysts attribute this decline primarily to the unwinding of basis trades. Previously, this strategy involved establishing long positions through spot ETFs and hedging with short futures to earn the spread. However, the annualized returns have recently dropped from 15%-20% to around 5%, prompting institutions to take profits. Additionally, the daily trading volume of CME Bitcoin futures has decreased to below $3 billion. Analysts suggest that as institutional demand shifts towards directly holding spot assets, the leverage in the futures market is significantly decreasing. #BitcoinFutures#OpenInterest#CME#BasisTrades#InstitutionalStrategy#SpotETFs#FuturesMarket#Leverage#TradingVolume#BlockBeats#Glassnode#CryptoMarket#BTC
