Almost every CLI program I've ever used in Windows has no problem with spaces in filenames, so I don't exactly why he's fixated on the GUI... But I had forgotten, computers aren't useful as tools to accomplish work, but as mechanisms to assuage intellectual inferiority complexes. He should advocate for punch cards again, since that would certainly stop morons from using computers.

> Almost every CLI program I've ever used in Windows has no problem with spaces in filenames, so I don't exactly ...

Just to clarify on what we think as problem could differ:

    C:\Users\hzhou>ls *.txt
    new  2.txt

    C:\Users\hzhou>ls new  2.txt
    ls: new: No such file or directory
    ls: 2.txt: No such file or directory

dir works fine for that.

:)

I actually didn't know that dir supported multiple globs for filenames! I've never had a need for that.

Super cool.

Um... no it doesn't. It takes each space delimited name as a new name. You will need to add "" and quote the names -- but Windows shell only has one level of quoting, (") which means you can't easily type the command you need. Unix shell is a bit better. Unix only appears worse because people do attempt scripting.

This is highly ironical, given this thread.

Some people seems to advocate for programs to be better than humans at globbing filenames.

That's a great point. Computers sure have the potential to deal with spaces just fine. But if textual interaction is a requirement, we can only have one of arbitrary filenames and clutter-free syntax.

Window and Linux shells have the same ideas about spaces in file names, which is that if they appear they need to be quoted or the space character needs to be escaped.

Outside of Make which has long and boring historical reasons for not supporting spaces well, just about every program is fine with spaces.

In UNIX shell, IFS variable can be set to an other characters, e.g. newline and tab, or to empty string.

To be fair to modern desktop users, a command line that doesn't redefine the word "command" to fit the constraints of the system would look something like this:

$ take this list of transactions and for each group of duplicate names show me the name and total dollar amount spent, sorted from highest to lowest

$ I think I have a SQL command for that. Are you feeling lucky? [y/n] y

Foo $25 Bar $20 Blah $15

$ Was this what you were looking for? [y/n]

> Which is not a problem. The command line was only one, historical UI. Not the be-all end-all of UIs,

A similar trend is happening in electronic communication: from letter to email, to text, to emoji's. The text is just one historical communication way and there's no reason it should be of any real interest to modern communicator as long as we have emojis ... wait, we've been there before.

Only the text can express things that emojis cannot. This is not true to GUI vs command line.

The GUI, which can include arbitrary number of text boxes for command line style entry, is a superset of what the command line can do.

This kind of interface is horrific for the use-case:

There is such a thing as a cluttered graphical interface, and some complexity cannot just be abstracted away.

That would be like saying that because I am able to write "First open this app by clicking on the upper-left icon, then click File, new File", would mean that text is a superset of the GUI because it can describe visual cues. An abstraction can always replace another, it does not mean it is a superset of it.

Take the source code for your GUI application, this is pure text. In the early days, there was shell code that would describe terminal GUI of sort to configure the linux kernel. This shell code is still commands read token per token with matching behavior. Because an abstraction can be traded for another (which could be argued to be a founding principle of computer science), does not mean that one is a superset of the other.
