I appreciate the idea, but the comma just looks horrible to me as part of a filename. I can imagine someone unfamiliar with the naming scheme to get confused.

I'd prefer to use underscore (when writing BASH scripts, I name all my local variables starting with underscore), but a simple two or three letter prefix would also work. I don't like the idea of a punctuation prefix as punctuation usually has a specific meaning somewhere and including it as the first character in a filename looks wrong. (e.g. Comma is typically used as a list separator and it's a bit of cognitive dissonance to see it not used in that context)

Underscore requires pressing Shift, however.

So you don’t use dotfiles? ;)

		On non-English keyboards (Serbian/Croatian/Slovenian, but as they are based on QWERTZ, I imagine German and possibly others too), both "+" and "-" might not require pressing Shift either, and are much better characters than comma.

		Well dotfiles demonstrate that punctuation can have a special meaning in filenames. I'm not convinced by "quicker to type" arguments as that's rarely the bottleneck, so I'm perfectly happy with using underscores in filenames and variables. I wouldn't use underscore as the beginning character of a filename unless it had a specific meaning to me (e.g. temporary files), so I'd be more inclined to use a two or three character prefix instead.

I use my_ as a prefix.

		That’s a more meaningful prefix than “,” at the expense of a couple more key strokes. I consider that to still be a win in the book of tab completions. I would replace underscore with “-“ or “.”

		I used to use "do" as a prefix e.g. "doBackup" Nowadays, I tend to skip using a personal prefix and just try to name commands with a suitable verb in front (e.g. "backupMySQL") and ensure that there's no name collisions.

		Whenever I see "my" as a prefix, it feels like such a childish "my first Sony" thing. I hate official sites using that.
