Dear bash experts,

I came across a script today that stubbornly did this for like 30 variables:

declare -rx FOO="${FOO:-}"
declare -rx BAR="${BAR:-}"
...

(So the variable left of the equation sign is the same as the one inside the curly braces. There is only a ":-" after it which assigns it an (empty?) default value, in case it is unset)

Can anyone explain what the reason for that could be? Exporting variables that might (or not) be unset/undefined? Making sure they have an empty value?

Thanks in advance!

This is a short book which you may read if you work on Open Source systems with bash installed as the default sh

Some Quotes

Variable names begin with a letter and consist of letters, digits, and underscores. Shell variables may be given values when a shell procedure is invoked. An argument to a shell procedure of the form name = value causes value to be assigned to name before execution of the procedure begins. The value of name in the invoking shell is not affected. Such names are sometimes called keyword parameters. Keyword parameters may also be exported from a procedure by saying, for example, export user box Modification of such variables within the called procedure does not affect the values in the calling procedure. (It is generally true of a UNIX process that it may not modify the environment of its caller without explicit request on the part of that caller. Files and shared file descriptors are the exceptions to this rule.) A name whose value is intended to remain constant throughout a procedure may be declared readonly.

Because this is a light book I will hunt for more in depth books on shells

Дизайн-токены: полный гайд по архитектуре и неймингу c примерами и задачками

Дизайн-токены — это язык, понятный как дизайнерам, так и разработчикам. Без него продукт получается разрозненным и неповоротливым. Токены и правильный нейминг помогают создавать новые разделы быстрее, а дизайнерам больше думать о сценариях и создавать визуал в рамках продукта, а не заниматься рутиной. Если в вашем коде и макетах до сих пор живут значения типа #0055FF — вы копите технический долг, ведь если понадобится изменить этот цвет на другой, придется менять и все компоненты, где используется это значение. А про разные темы вообще можете забыть... В конце статьи будут ссылки на доп. материалы из реальных дизайн-систем, откуда я брал информацию. Изучить тему

Model-D with DI

“What cha doing, Grandpa?” Todd asked.

“What’s it look like? I’m #cranking the engine. You want to try?”

“Naw. I got a new car, a Chevy Roadster. This here Ford Model-A starts hard.” Todd kicked a car tire.

“This baby is one of those newfangled Model-Ds, Professor Muskrat been touting. This car don’t need gas, the engine is silent, no flat tires, and only smells a little of sulfur. Come with DI and even drives itself while you sleep.”

“Sounds complicated, Gramps. High-tech stuff has lots of #variables. What’s DI anyway?”

“Demon Intelligence. But the d*mn demon won’t wake up.”

The rogue peered through the trees at the encampment below. "Guards, crossbows, dogs and alarms..."

"How shall we split them?" asked the barbarian.

"Too many #variables to work with." He opened his belt pouch. "But I have an idea."

"Smoke bomb? Poison?"

"Nah." Grinning, the rogue tipped out some dice. "Roll you for it."

His companion snorted. "No way, they're loaded."

Starting with Ansible is easy. Fast. Then the data grows. Variables haunt. Data structures creep in. Ghost Operators don't repeate. They re-architect.
