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

Systematic Attacks on Religious Minorities' Shrines and Places of Worship in Syria
W #Hama: An extremist terrorist group has destroyed a religious shrine belonging to the #Alawite community, known as “Sheikh Muhammad al-Maghribi,” located in the village of #Asila in Masyaf, in the Ghab Plain in the rural countryside of Hama Governorate, yesterday 21 March 2026.
#Alawite: It is worth noting that attacks on Alawite religious shrines began following the fall of the regime, reaching their peak during the #massacres carried out against Alawites on the Syrian coast by al-Jolani’s forces. Incidents of assault on Alawite shrines have continued repeatedly, to the point where barely a month passes without an incident involving the bombing, desecration, or burning of shrines across various Alawite regions.
#Druze: Similarly, shrines belonging to the Druze community were subjected to comparable attacks, including vandalism, arson, and bombings, during the massacres of July 2025 in #Suwayda, carried out by the forces of al-Jolani’s terrorist regime.
#Christians: A church in #Damascus was also bombed in June 2025, in addition to attacks on churches in #Homs and the rural Homs region in the #alQusayr area. The massacres that took place in As-#Suwayda likewise saw the burning and destruction of three churches.
