reload_flag=""
if [[ -n "${DEBUG}" ]]; then
reload_flag="--reload"
fi
if [[ -n "${WORKER_COUNT}" ]]; then
workers=${WORKER_COUNT}
else
workers=2

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.

🍿 Cameron Diaz breaks her retirement and returns to action with Jamie Foxx in 'Back in Action'!
📆Release Date: January 17, 2024
🎭Genre: #Action · #Comedy · #Espionage
🎬 I can't contain my excitement: Cameron Diaz returns to the big screen after 11 years alongside Jamie Foxx in 'Back in Action'. In this adrenaline-fueled espionage comedy, they play a pair of former CIA agents who must get back in the game when their cover is blown. 🔥💥
The most interesting thing is seeing Diaz and Foxx together again after 'Any Given Sunday' and 'Annie'. Plus, the cast is impressive: Glenn Close from 'Fatal Attraction', Kyle Chandler from 'Super 8', and Andrew Scott from 'Sherlock'. Directed by Seth Gordon, the genius behind 'Horrible Bosses'. This is a comeback you won't want to miss! 🎉🎥
🍿 The Phoenician Scheme: Benicio del Toro, a Nun, and Six Plane Crashes ✈️😵💫
📆Release: May 30, 2025

Wes Anderson (The Grand Budapest Hotel,Asteroid City) is back at his most eccentric: Benicio del Toro leads this visual satire as a bruised and armed tycoon who hands over his empire to his daughter, a knife-wielding nun played by Mia Threapleton (yep, Kate Winslet’s daughter). The cast is wild: Tom Hanks, Bryan Cranston, Richard Ayoade, Scarlett Johansson, Cumberbatch, and even Michael Cera in peak “Wes mode.”
Shot in Germany with a score by Alexandre Desplat, the film oozes Anderson’s signature nostalgic absurdity, but with a sharp rhythm that echoes his best work. Sure, the aesthetic is familiar, but when Wes nails it, it’s not formula, it’s pure style. And this one smells like a full-blown comeback. 🎨💣

Jeffrey Epstein nebol zakladateľom siete. Bol dedičom.
Skrytou pravdou je, že táto vydieračská sieť nevznikla v 90. rokoch. Bolo to „spravodajské dedičstvo “ odovzdávaná z otca na dcéru.
Ghislaineiným otcom bol Robert Maxwell, mediálny magnát a legendárny superšpión Mossadu.
Operácia začala s ním: zbieraním „kompromitujúcich materiálov“ na politikov pre Izrael.
Keď zomrel a bol pochovaný v Jeruzaleme so štátnym pohrebom, na ktorom sa zúčastnili šéfovia spravodajských služieb, jeho dcéra prevzala „rodinný podnik“ s Epsteinom.
Nebolo to len obchodovanie s ľuďmi. Je to desaťročia trvajúca vydieračská operácia sponzorovaná štátom.
