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

YouTube Issues and Economic Updates 🔧 Users in Russia report ongoing issues with YouTube, marking another decrease in platform traffic, as confirmed by Google. 📊 The Russian Communications Ministry (RKN) plans to acquire data on user attempts to access blocked sites, though it already collects some relevant data. ⚙️ The Ministry of Economic Development aims to increase processing limits to enhance labor market flexibility amid personnel shortages. 📈 Predictions suggest the information security market in 2024 could grow by 30% to reach 593 billion rubles, though other estimates are lower. 📺 Yandex is negotiating with Haier, TCL, and Huawei for the installation of its OS on all their TVs supplied to Russia. 💰 AI search engine Perplexity successfully raised $500 million at a valuation of $9 billion, a significant increase from its earlier valuation of $1 billion. 🇺🇸 In the US, an investigation has been initiated against TP-Link over national security concerns, as they hold 65% of the domestic router market. #YouTube#RKN#EconomicDevelopment#MarketGrowth#InformationSecurity#Yandex#Perplexity#Funding#TPLink#NationalSecurity#Russia#TechNews#AI#Router#Television#DataPrivacy#UserExperience#TrafficIssues

YouTube Issues and Economic Growth Users in Russia again report issues with YouTube, causing a traffic drop noted by Google. The Roskomnadzor is seeking data from providers on user attempts to access blocked sites, despite existing data collection measures not aiding user identification. The Ministry of Economic Development aims to raise processing limits to improve labor market flexibility amid staff shortages. The cybersecurity market is projected to grow by up to 30% in 2024, although some estimates suggest only 10-15% growth due to high interest rates and tax burdens. Yandex plans to negotiate with Haier, TCL, and Huawei to install its OS on all TVs sold in Russia. AI search engine Perplexity secures $500 million funding, raising its valuation to $9 billion, up from $1 billion in April. In the U.S., the investigation into TP-Link for potential national security threats begins, as it commands 65% of the U.S. home router market. #YouTube#Russia#InternetIssues#Roskomnadzor#LaborMarket#Cybersecurity#Growth#Yandex#AI#Funding#Perplexity#TPLink#NationalSecurity#TechNews#MarketTrends#Television#Haier#TCL#Huawei#EconomicDevelopment#VPN
