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.

TON Launches Loyalty Program
❤️ The TON ecosystem has introduced the TON Loyalty Program — a Tapps rewards layer that turns everyday actions in Telegram Mini Apps into collectible points with built-in “cashback.”
How Tapps mechanics work:
🔵 Users open any partner Mini App
🔵 They spend Stars (games, purchases, donations — as usual)
🔵 A smart contract automatically credits Star Points to their TON wallet
🔵 Accumulated points can be redeemed for:
• Telegram Premium
• Exclusive & Rare Telegram Gifts
• Surprise Gift-Boxes
Why it’s a welcome addition:
🔵 A portion of Stars spent is returned as points
🔵 All Mini Apps share a unified loyalty system
🔵 An on-chain counter shows exactly how many points you’ve earned and for which actions
For long-time Star users, it’s a handy form of cashback. For newcomers, it’s a great reason to explore TON Mini Apps and see the benefits firsthand.

☀️Meet the Mini App from Architec.ton!
Yesterday Architec.ton team have released their wallet, but banks (shares) can still be purchased to receive $ARС tokens and become a co-owner of the project. Currently the price of $BNK is 1.5 $TON (~$11)
The team is currently working on fixes. The #swap button is not yet available. The bugs will be fixed within a short time.
🔜About staking and liquidity
All $BNK and $ARC were successfully credited to those who purchased them. If anyone has questions, please contact support @architecton_support.
📈$BNK can be staked now if you want to earn $ARC income.
Liquidity in $BNK and $ARC has not yet been added to the swap, so it will not be possible to sell them on the DEX now. This was done according to pre-agreed principles in order to prevent a dump, since the task of the project team is to ensure long-term #liquidity due to the demand for our token. However, the team’s plans include entering the stock exchanges.
