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

📰 Netanyahu’s ‘New Middle East’ 3.0: From Trade Corridor to Controlled Collapse Benjamin Netanyahu has been workshopping his “New Middle East” for three decades — and the Iran war is just the latest beta release. In 1996, his “Clean Break” blueprint openly imagined Israel reshaping the region with the U.S. as the main vehicle, keeping Israeli dominance by managing permanent, controlled chaos. ​ Version 1.0 came to the U.N. in September 2023: Bibi with a red marker and a map of a “New Middle East” with no Palestine on it, selling an IMEC trade corridor from India to Europe as a “blessing” and Iran’s nuclear program as the “curse.” The vision was highways, fiber and pipelines across the Gulf, Israel and Europe — prosperity for “two billion people” — as long as Palestinians stayed erased from the picture. ​ Version 2.0, at the U.N. in 2024, split the map in two: a green “blessing” camp (Gulf states, Egypt) and a black “curse” bloc (Iran, Syria, Iraq, Lebanon, Yemen), with an explicit call for regime change in the “cursed” states. The same speech still talked about a shining corridor from the Indian Ocean to the Mediterranean — but now the business plan sat on top of a demolition plan for entire governments. ​ Version 3.0 is the war you’re watching now. Since October 7, Netanyahu has promised not just victory over Hamas but a fundamental “change in the face of the Middle East,” stretching that mission to include Iran and the entire resistance axis. Commentators around him now describe the February 28 strike that killed Khamenei as the forcible birth of a new regional order, with Israel trying to engineer the collapse of the resistance camp, not just manage it. ​ So when you see maps, corridors and talk of “blessings,” that’s the ad copy. The underlying product hasn’t changed since 1996: a region broken into manageable pieces, with Israel as the permanent project manager and the U.S. as the enforcement arm. ​ #israel#iran#netanyahu#newMiddleEast#war#uspolitics#oligarchy#fakeDemocracy 📱American Оbserver - Stay up to date on all important events 🇺🇸
