Dialog output problem. How to use checklist?

Question

linux

I make a bike for myself. Arch linux installation automation. I use the dialog utility.
I want to get a menu with multiple choice, for which I use the --checklist parameter.
what needs to be output resulted in the form
en_US.UTF-8 UTF-8 ON \
en_AU.UTF-8 UTF-8 OFF \
and saved it to a temporary file. I'm trying to output in the form
LOCALE="$(dialog --checklist 18 60 11 ${tempYYY.tmp} )"
and I'm getting an error about the number of tags or the number of parameters..
Thanks in advance

Answer 1

Start making your own project that has some practical value and learn what you need as you build it.

Answer 2

Learn [Reading Documentation] and [Reading Books]

Answer 3

In order not to have porridge, it is advisable to read a book, while those topics that you know can be viewed diagonally.
If you use smart pointers(make_shared, make_unique, etc.), move semantics( std::move, etc.) and write templates when needed(template ... - sometimes the speed of work increases several times, which is very it's a shame without templates), you can write multithreading and know how to use SIMD, then you can say that you have a pretty good knowledge of C ++. Of course, there are a lot of subtleties left, like the exceptions flying out at runtime at the moment when you don’t expect it, but this comes with experience.
I advise you to look at the source code in C ++, which is written in Yandex or Google and trending .
If something is not clear in the source code, then this is what should be tightened up.
