        If a directory has multiple words in it I usually do kebab case: i-like-mine-in-a-way-i-can-read-them-properly. Both easier to read and type than pascal case.

        For more complex filenames I use a combination of kebab-case and snake_case, where the underscore separates portions of the file name and kebab-case the parts of those portions. E.g. movie-title_release-date-or-year_technical-specifications.mp4

                I have issues with Docker a lot. Example: Rename a file from “File.js” to “file.js” in a dependency and it’s like something caches the old name so even when I redownload or install that dep it tries the old name and fails to find the file. Might just be me and my tomfoolery

                  if you’re renaming from File.js to file.ts, which is also changing suffixes instead of just capitalization, then that couldn’t be explained by case sensitivity, unless it was a typo and you meant File.js to file.js

                  This is likely because docker runs Linux in a VM on MacOS right?

                  We’ve had similar problems with stuff that works on the developers Mac but not the server which is case sensitive. It can be quite insidious if it does not cause an immediate “file not found”-error but say falls back to a default config because the provided one has the wrong casing.

All of my mac machines arrived brand new, case insensitive. Granted that’s only 3 so far, but it’s a smattering from 2019 onward. All the literature online points to this being the default too

        I don’t know about dangerous, but case-insensitive Unicode comparison is annoying, expensive and probably prone to footguns compared to a simple byte-for-byte equality check.

        Obviously, it can be done, but I guess Linux devs don’t consider it worthwhile.

        (And yes, all modern filesystems support Unicode. Linux stores them as arbitrary bytes, Apple’s HFS uses… some special bullshit, and Windows uses UTF-16.)

            If you did it would likely break something as it’s one of only two characters not allowed in a file name (the other being null).

            You can do a lot of funky stuff within the rules though, think about control characters, non-printing characters, newlines, homographs, emojis etc. and go forth and make your file system chaos!

            .C came first. I don’t usually use it though; I usually use .cc or .cxx, but if I’m making some tiny test source, I often use .C. I’m strongly opposed to the .cpp extension because calling C++ “CPP” leads to confusion with the preexisting (before C++) use of the initialism to refer to the C preprocessor. There’s a reason why CPPFLAGS refers to preprocessor flags and CXXFLAGS refers to C++ flags.

              As someone said you solution is to symlink or setup LVM volume groups for different mount points. Essentially, it’s all or nothing. You can’t just put a single program on a different disk without then taking all those files and manually symlinking them to the right place. It’s honestly one of the biggest Linux oversights.

              Symlink your desired location on the target disk to the place the system thinks the software should go. (In my case, /usr/local/games is a symlink to a different drive.)

          XDG specifies the capital names, but to be nitpickingly technically precise, linux systems don’t do this. It mostly is done by the distribution maintainers, and the XDG specs. A base system does not usually have a notion of anything beyond your $HOME.

          Try adding a user: sudo adduser basicuser. If you ls -al ~basicuser you will see it’s almost empty, just the .bashrc (or in my fedora, there’s some .mozilla crap in /etc/skel that also gets bootstrapped).

    I love how many people brought up the Turkish “I” as if everyone here is on the Unicode steering committee or just got jobs for Turkish facebook.

    I, an English speaker, have personally solved the problem by not having a Turkish I in the name of my Downloads directory, or any other directory that I need to cd into on my computer. I’m going to imagine the Turks solve it by painstakingly typing the correct I, or limiting their use of uppercase I’s in general.

    In fact, researching the actual issue for more than 1 second seemingly shows that Unicode basically created this problem themselves because the two I’s are just seperate letters in Turkic languages. https://en.m.wikipedia.org/wiki/Dotted_and_dotless_I_in_computing

    If you nerds think this is bad try doing Powershell for any amount of time. It is entirely case-insensitive.

        Well letters don’t really have a single canonical shape. There are many acceptable ways of rendering each. While two letters might usually look the same, it is very possible that some shape could be acceptable for one but not the other. So, it makes sense to distinguish between them in binary representation. That allows the interpreting software to determine if it cares about the difference or not.

        Also, the Unicode code tables do mention which characters look (nearly) identical, so it’s definitely possible to make a program interpret something like a Greek question mark the same as a semicolon. I guess it’s just that no one has bothered, since it’s such a rare edge case.

            In cases where something looks stupid but your knowledge on it is almost zero it’s entirely possible that it’s not.

                I and l also look identical in many fonts. So you already have this problem in ascii. (To say nothing of all the non-printing characters!)

                If your security relies on a person being able to tell the difference between two characters controlled by an attacker your security is bad.

      that’s not how language works though, in human language (i know this can be confusing) d and D are the same letter just in different forms.

      It’s one thing to have case sensitivity in programs doing data manipulation, that makes sense because you don’t want the program to accidentally use the wrong files without supervision.

      But when you have an interactive prompt you know what you’re doing, you can see if you entered the wrong directory, and you’re generally going to be working in directories that you have yourself organized.

                Because usability. If you have the files down down1 down2 downxyz and download and the user only knows that it was “something with down” it’s best to show the user everything matching “down*” and let the user decide what’s the correct one.

                Also I’m not sure but wouldn’t your expression show everything if only one character would be entered?

                And again I don’t see this solving anything if the entered string actually contains other characters then what’s in the file (D != d)

                Yes one could argue that some form of advanced algorithm or even AI could be used to identify such use case like download and Download but this is programming Humor, not linguisic Humor.

                  would it not be usable to have completion be case insensitive? I seem to be able to use that… if I only remember “something with down”, I could just as easily forget the capitalization of “down”. maybe I have downloads and Down? why not show everything matching case insensitively and let the user decide what’s the correct one?

                  I didn’t really understand what you thought the regex did incorrectly, but I think the regex works fine, at least for most implementations, anyways what I meant is just a case insensitive version of the regular substring completion, which shouldn’t be too difficult to make.

                  The only thing it solves is the frustration of having to look for a file/directory twice because you didn’t remember it’s capitalization. again, those are different characters just like a do and downloads are different strings, but it can be easier for users if they can just press tab and let the computer fill the part of the name the don’t remember (or don’t want to type).

                  you don’t need an advanced algorithm or and AI, there are many easy ways to make completion case insensitive (like that regex for example). Issues involving names are inherently somewhat linguistic, but either way interactive shells are meant to be (at least somewhat) usable to humans, and as seen by the post, some people would prefer completion to be case insensitive.
