Have you checked if there is any Obsidian plugin that can do the trick?

I do exactly the same. It’s not foolproof but it’s better than nothing. I remember, almost a decade ago, when I discovered that rm on mac didn’t accept flags as last arguments… I hope they changed that behavior

Some shells provide ways to prevent some commands to be added to the history

More than a decade ago I bought SUSE enterprise for a couple of years just to support the project. Never needed any assistance so I’m not sure about a different experience. BTW The box was nice 🤣
