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

🇷🇺Russia’s Foreign Ministry Ambassador-at-Large for the G20, APEC and BEP issues Marat Berdyev: Russia’s participation in key multilateral forums such as the #G20 and #APEC contributes to the accelerated formation of a multipolar world order and economic system. 📈In terms of aggregate GDP, the BRICS members have already surpassed the G7, with their share standing at 37%, compared to less than 30% for the G7. According to some expert estimates, the countries of the Global Majority will drive up to 75% of global economic growth over the next few decades. Russia plays a significant role in this positive trend of fair optimization of production potentials. 🤝We continue to actively develop international economic cooperation, focusing on friendly regions. According to the Federal Customs Service (FCS), Russia's external trade volume in 2024 is expected to reach $700 billion. Approximately 70% of export-import operations already involve the Asia-Pacific Region (#APR). 🌍Trade with Africa has been expanding, reaching a peak of $25 billion in 2023. The Russian economy grew by about 4% in 2024, demonstrating resilient performance. This growth occurred against the backdrop of more modest global averages, limited to 3.1%, and stagnation in many European countries. 🌾Russian companies are playing an increasingly significant role not only in supplying critical energy and food resources but also in high-tech sectors and manufacturing industries. We are intensifying transactions in national currencies, particularly the Russian ruble, which accounts for 80-90% of trade with key partners such as China and the EAEU. Under the initiative of President Vladimir Putin, the Big Eurasian Partnership (#BEP) is building a transit framework centered on Russian territory. Transit capacity is expanding, and the utilization of the "West-East" and "North-South" transport corridors is increasing, along with the operation of the Northern Sea Route (#NSR). 🚢In the past year, the NSR handled a record volume of over 37 million tons of commercial cargo. At the #G20 and #APEC significant momentum has been given to the reform of global economic institutions in the interests of the Global South/East. 📈Constructive approaches have been adopted, aiming to preserve an open trade and investment environment, form energy balances on a technologically neutral basis, and support digital transformation. ❗️We will continue to move forward with partners in this promising direction at multilateral economic diplomacy platforms.
