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.

#Commentary: #Oromia’s New Regulation: Legalizing construction on illegally possessed land, enabling geography-based discrimination
Oromia’s Regulation No. 259/2026 (March 2026) legalizes illegally built properties—yet excludes #Shaggar, #Adama, and #Bishoftu. Hassen Mama Muse argues, "This geographic exclusion creates a two-tiered system, violating constitutional equality."
The law covers construction projects from 2013 to 2026 that meet the criteria but excludes some residents from facing demolition. This contradicts Article 25 of #Ethiopia’s Constitution and treaties like the #ICCPR. The regulation also fails Lon Fuller’s "internal morality of law" and exceeds the Council’s authority under Proclamation No. 242/2021.
According to the author, urgent reforms are needed: include all cities, compensate evictees, and review constitutionality." A fair framework must protect all equally," he emphasizes, "or entrench inequality as reform."

News: EPRP calls for nationwide protest on May 8 amid concerns over electoral conditions
The Ethiopian People’s Revolutionary Party (#EPRP) has called for a nationwide peaceful protest to be held on May 8, 2026, citing what it described as the absence of “enabling conditions” for a credible election in #Ethiopia.
In a statement sent to Addis Standard today, the party said the planned demonstrations will take place in several major cities, including #Addis_Abeba, #Mekelle, #Bahir_Dar, #Gondar, #Hawassa, #Adama, and #Ambo, urging #Ethiopians to join what it described as a peaceful effort to demand political reforms.
The EPRP said it supports the transfer of power through elections but argued that current conditions do not allow for a “free, fair, and credible” vote. It accused the ruling Prosperity Party of attempting to conduct what it termed a “pseudo-election” aimed at extending its hold on power, describing the process as
