A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.

- Posts must be original/unique
- Adhere to Lemmy's Code of Conduct

Thank God they went with file name extensions so we didn't have to preface every source .txt file with header content to instruct the editor about what kind of content it would have.
Why do I need to put that at the start of bash, desktop, and html files then?
Because both ways are used. Microsoft relies on file names, linux on the first bytes of the file.
Not quite correct. For html, that is to signal standard compliance, you can leave it away and the browser will still handle it. For the bash one, all (most) shell scripts use .sh, so you need to give a shebang to tell the loader which executable (sh, bash, zsh, csh, ...) to use
Also on Linux xdg does take file extensions into account, just executables do not
You're right, my comment was oversimplified.
