@G-Man Naturally you're very right indeed. Yet.. I don't know.. if this answer of mine has any little reason to exist among the other excellent ones by fra-san and Kusalananda is possibly because it handles only a couple of particular concepts in an (intentionally) overly rich way, though necessarily stripped of collateral details because otherwise it'd be even longer and tedious. A tale for absolute beginners, more than a proper description of what declare does. Perhaps your very comment, which I upvoted, may serve well as the footnote you mention ?

You mention foo="bar" and declare foo="bar". You might want to mention (if only in a footnote) that, in a shell function, declare foo="bar" creates a local variable and foo="bar" creates a global variable.

@JohnDoea I see. Maybe you might just leave this topic for the moment. It’s probably too soon to grasp this concept at the current point of your learning. Anyways I’ve expanded my answer with more examples and also a little personal addendum as to how I think you should proceed. I’ve also put horizontal lines to delimit the general explanation of declare from the specific explanation of -n from the personal addendum. I’ve also done a bit of rewording here and there but nothing substantial, so I think you may just re-read the -n part plus the little addendum.

| Apr 6, 2019 at 2:07 | comment | added | user149572 | LL3 I like your answer very much and I thumbed up: I finally understand what declare does --- not declaring variables but declaring their attributes; yet sadly I lost track when you started to explain what is a name-ref. I got no idea what it does and why to use it. | |
