Post History

Shell scripts, BASH, batch files, PowerShell etc etc are all on-topic here and so questions about command line commands ought to be as well. 

We may however require the question to include enough relevant details like which OS, which version/distro or otherwise the question is probably off-topic.

None of this is really mandatory prerequisite knowledge for programming - I'm very rusty at it all personally. The overall trend in programming during the last 20 years is to move away from command line and make files etc towards graphical IDEs that handle the linking and building. For very sound reasons: with IDEs, the programmer can focus on programming instead of cumbersome side tasks such as writing make files or linker scripts. (You can of course still tweak builds, compiler options etc when there's a need, but you typically don't _have_ to.)

It may be meaningful to assemble some sort of help post with minimum expected prerequisite knowledge before starting programming. However, coming from the low-level side of things, I would rather list things like binary, hex, boolean algebra, basic electronics etc as prerequisites before learning programming. So these prerequisites are quite subjective depending on what type of programming you end up doing - "programming" is a really broad topic, software engineering even more so.
