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

🔺Continuation from above @rednile12 🔍 Why this confirmation matters The unveiling is corroborated by multiple defence-focused outlets with photos and videos from the expo, including: 🔗Defence Blog (breaking report): 🔗Defence Security Asia (in-depth analysis): ▪️ Additional confirmation came from UNITED24 Media and Ethiopia’s Institute of Foreign Affairs (IFA), reinforcing that this is consistent, cross-verified reporting, not media hype. ▪️Variants on display suggest ISR-focused configurations, while reporting confirms strike-capable Orion-E versions are part of the acquisition — aligning with the platform’s dual-role MALE design. ▪️While no formal press release has been issued by Addis Ababa or Rosoboronexport (standard practice for sensitive arms deals), the public exhibition itself functions as de facto confirmation. 🛩️ Aviation Expo 2026 — key context 📍Location: Bishoftu Air Force Headquarters 🎖️Occasion: 90th anniversary of the Ethiopian Air Force — the Black Lion 📅Dates: January 23–27, 2026 🌍Theme:“Flying Forward, Building a Shared Future” 🛰️ What Ethiopia is actually acquiring According to Defence Security Asia: ▪️The Orion-E is a medium-altitude, long-endurance (MALE) UAV capable of 24+ hours endurance ▪️Payload capacity of up to 250 kg, supporting electro-optical/infrared sensors and precision-guided munitions ▪️Operational altitude of roughly 7,500 meters, designed to remain above most MANPADS threats ▪️Optimised for persistent ISR and precision strike, particularly in large, rugged, infrastructure-poor environments like the Horn of Africa 💸 The deal is widely assessed to be worth USD 300–500 million, likely covering: ▪️Multiple airframes ▪️Ground control stations ▪️Training and operational support ▪️Weapons integration and sustainment 🌍 Strategic implications The Orion-E unveiling marks: A decisive leap in Ethiopian airpower modernisation ▪️ A clear shift toward sovereignty-centric, non-Western defence partnerships, especially after Western arms restrictions during the Tigray conflict ▪️Russia’s first real breakthrough in exporting MALE UAVs, validating long-stated claims by Rosoboronexport chief Alexander Mikheev that multiple Orion contracts had been signed 🔹 Regionally, Ethiopia’s drone modernisation directly affects: ▪️Horn of Africa security dynamics ▪️The Red Sea and Bab al-Mandab corridor ▪️Deterrence, escalation control, and power projection through persistent unmanned dominance 📌 Bottom line This is not speculation, not propaganda, and not unverified chatter. Ethiopia has now visibly entered the MALE-class drone club, becoming the first foreign operator of Russia’s Orion-E and a pace-setter in Africa’s next phase of aerial warfare. The skies over Africa are changing — and Ethiopia is choosing to shape that future, not react to it. — RedNile Media🌊🧭 📡@rednile12 Geopolitics | Multipolarity | Sovereignty | Strategic Reality #Ethiopia#OrionE#RussianDrones#AfricanAirpower#DroneWarfare#EthiopianAirForce#HornOfAfrica#RedSea#MilitaryModernization#Geopolitics
