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

🇺🇸🇮🇱🇵🇸⁣Ben is finally waking up to the strategic intent behind October 7. On October 6 no one was seriously talking about a #Palestinian State. Since October 7, everyone is. All Hamas had to do was provide #Israel the opportunity to show the world the true face of its genocidal existence. @MostMoralArmy

#Palestinian Civil Defence is currently recovering remains of #Gazan martyrs which they couldn’t previously reach. Many of these bodies have decomposed. Gaza’s Civil Defence Spokesperson Mahmoud Basal said that the number of martyrs whose bodies evaporated reached 2848 martyrs. #Israel’s use of internationally forbidden arms stands behind this phenomenon. The #Palestinian Media Center said that these weapons, which haven’t been identified, melt and evaporate bodies due to the extreme heat produced by these weapons.

#Commentary: #Ethiopia’s Policy Realignment: From #Pan_African Beacon to Client State On 31 March 2026, the UN Human Rights Council adopted a resolution condemning #Israel’s actions in the occupied #Palestinian territories and the Syrian Golan Heights. Thirty-one countries supported it; Ethiopia was among only three in opposition. Sidoc Haytu describes the move as “a profound betrayal of the Pan-Africanist and anti-colonial principles that once defined the Ethiopian state.” While officials frame the vote as pragmatic, he argues it serves elite interests, noting “the calculation was not performed on behalf of the 120 million Ethiopians.” Contrasting Ethiopia’s past stance, he claims, “When Ethiopia votes at the #UN… it is voting as a client of…Tel Aviv,” urging a reversal: “Ethiopia will not stand with colonizers.” https://addisstandard.com/?p=56716
