That only affects whitespaces within quotes though. Still, fair point, except I just tried a bunch of stuff in both bash and zsh and touching a file works, echoing a string works, then I stopped so I don’t know about the asterisk but we have already veered far away from what OP said: “normal foor (sic) loop with whitespace in file names” - whereas what you had seems significantly more advanced than a “normal” foor (sic:-P) loop.
Notably, Mac OSX right out of the box uses zsh. I haven’t touched “standard” personal distros for a number of years but a quick search suggests that Mint, Ubuntu, and NixOS all use bash by default - which halfway though not entirely surprises me? Anyway if OP wants to change their default shell to something more advanced, that would be fine for common every-day usage, though asking for bash itself to now be changed after decades of backwards compatibility seems a non-starter to me. There are reasons for why it works as it does, and those reasons have nothing to do with it being “old”, but rather b/c it “works”.
And the underlying reason for that is b/c we are still using keyboards. The addition of mice as HUDs enabled drag-and-drop, and perhaps some kind of glove or fingertip reader or eyesight-tracker may allow the same, like Minority Report (an old movie) or Iron Man style pinching an “object”, grabbing it and letting it go, is basically just another style of “mouse”. Afaik, there hasn’t been even a hint of anything truly revolutionary for all this time. Although I can envision one such idea: combining keyboard+“mouse” in a more intelligent way, like if you start typing a command, then fix your eyes on the screen to a particular file and perhaps flick your eyes in a particular direction to indicate acceptance and it could fill it in for you, without having to move your hands away from the keyboard. With glasses and ubiquitous cameras everywhere now, we might see something like that in a few decades? Though it would put further pressure onto privacy concerns over having a camera watching every move you make.

With Debian-based distros, it’s actually a bit weirder. They use dash as the global default shell (i.e. for executing sh scripts). dash has basically no code for interactive use, so it’s supposedly faster and more secure. It is POSIX-compliant, so the treatment of whitespace should be identical, but it doesn’t support any of the added features of bash.
If you open up a terminal emulator, they’ve got that set up to use bash by default, so dash is supposed to be invisible to the user, but well, spoilers, it’s not. If you switch to a TTY, for example, it launches there and makes the TTY look completely broken.
Yeah, Apple moved to Zsh as default some years back, which is the main reason I’m familiar with its differences in terms of parameter expansion. They still ship Bash 3.2 with macOS, but they can’t ship newer versions due to GPLv3 licensing, or something like that. So they had the motivation to switch.
In the Linux world, there’s no great motivation to change the default, because Bash 5.x is already comparable to zsh in terms of features, and it’s what everyone is already familiar with.
Perhaps I misunderstood OP’s question. I figured they meant using variables. Otherwise I don’t know how to make sense of it.
Admittedly, I too am not certain why “noone inprove bash such that you can write a normal foor loop with whitespace in file names?” :-P I just noticed that not only was “foor” loop misspelled, and “noone” is likewise improper (should be “no one” or “nobody”), but “inprove” is also a “performance improvement company that helps clients implement their internal continuous improvement programs more effectively, and achieve better, more consistent and sustained results”, according to Google’s (SEO) search feature:-P
Therefore, I have little trouble believing that they wanted all of bash to be changed - for free ofc - so that they could do something like:
touch “Iron Man”; mv Iron Man The Greatest Movie of All Time!?
And the computer would auto-magically figure out that since mv is a command involving files, and “Iron Man” is a file that exists, that it should be the first argument and the rest of the text is the second argument. i.e., why learn how bash works, when you can make a post to [email protected] and put hundreds of programmers to work for you to change the entire world, at your beck and call, while also working in how ashamed they should be that they haven’t done that effort preemptively?
Which ngl, might be a good idea. Or, you know, OP could learn to use tab-complete that already does that. I should have mentioned that I suppose… but it seems too late now b/c I doubt the mods will let this post remain for too much longer. Even if you were correct and they meant variables: they never actually said that, which makes this communication really difficult to both guess what OP might have meant and also solve their problem for them, on top of them being willing to learn on their own. But we can do better on our end too: perhaps we could create a community specialized in providing help to newcomers who want to learn linux - like what resources can they read/watch/play with, to help them get started? To be clear, *I’m* not offering to start that!!
