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

Iranian Hackers Have Hacked the Personal Mailbox of FBI Director Cash Patel ⚠️ Iranian hackers on Friday claimed they had accessed FBI Director Kash Patel's personal email inbox, publishing photographs of the ‌director and other documents to the internet. 💻 On their website, the hacker group Handala Hack Team said Patel "will now find his name among the list of successfully hacked victims." The hackers published a series of personal photographs of Patel sniffing and smoking cigars, riding in an antique ⁠convertible, and making a face while taking a picture of himself in the mirror with a large bottle of rum. Justice Department official confirmed that Patel's email had been breached and said the material published online appeared authentic. The FBI did not immediately respond to a request for comment. The hackers did not immediately respond to messages. Handala, which calls itself a group of pro-Palestinian vigilante hackers, is considered by Western researchers to ‌be ⁠one of several personas used by Iranian government cyberintelligence units. Handala recently claimed the hack of Michigan-based medical devices and services provider Stryker (SYK.N), opens new tab on March 11, claiming to have deleted a massive trove of company data. The WP was not able to ⁠independently authenticate the Patel emails, but the personal Gmail address that Handala claims to have broken into matches the address linked to Patel in previous data breaches ⁠preserved by the dark web intelligence firm District 4 Labs. Alphabet-owned Google, which runs Gmail, did not immediately respond to a request for comment. A ⁠sample of the material uploaded by the hackers and reviewed by the WP appears to show a mix of personal and work correspondence dating between 2010 and 2019. 📊 #kash#patel#iranian#hackers 📱American Оbserver - Stay up to date on all important events 🇺🇸
