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

💨 Nothing on the road will scare you after this 🇸🇪 In Sweden, driving schools teach students how to handle a car in all kinds of tricky conditions. 🚗 And yes — passing a skid-control test is mandatory before they can even get their license. #driving@Car_News

🚗🇺🇸1 IN 3 US PARENTS FEAR TEEN DRIVERS WILL CAUSE DEADLY CRASH 🔹 University of Michigan poll: 33% worry their young driver could cause accident — but 96% think their kid drives "average or better" 🤔📊 🔹 Half (51%) witnessed unsafe behavior: 44% saw aggressive driving, 25% caught texting while driving, 17% saw impaired/sleepy driving 😱🚨 🔹 Only 24% imposed consequences — most just take keys (6%), refuse car (8%), or threaten insurance cuts (6%) 🔑💳 🔹 Parents who saw road rage LESS likely to rate teen as bad driver — massive blind spot putting lives at risk 🙈💀 American teens NOT ready for the road.

🔥🏁Koenigsegg Regera Breaks Rimac Nevera's Record in 0-400-0 Challenge 🏁🔥 🏆 The music didn't play for long: Rimac Nevera's record in the 0-400-0 km/h acceleration-braking challenge lasted only a month. The Croatian hypercar surpassed the previous record holder, Koenigsegg Regera, clocking in at 29.94 seconds. 🇸🇪 The Swedish brand shrugged and sent the Regera back onto the track. Guess what? 28.81 seconds. How do you like that, Mate Rimac? 🥇 The margin of victory was 1.13 seconds, which in such a discipline, it must be said, is quite impressive. Surely, Rimac will have to respond. Competing is possible, but it will definitely require some effort. 🏎️Interestingly enough, the Regera has already been discontinued, with the last unit delivered to its owner in 2022. So why set a record with a car that is no longer in production? Koenigsegg answers bluntly: "Because it can!" The Regera remains superior to any newcomer. And it has proven it once again. 💥To outperform a significant rival - an electric car that has just set 23 records - is both impressive and beautiful. 💥 #Koenigsegg#Regera#driving#car
