And if he’s on / (root) on most common distros, there won’t be any dirs with . (dot) in their name. Unless this matches the dot from the cwd, in which case this is the same as “rm -rf /“? Now I’m curious, I don’t often perform operations on the cwd using dot.

At least bash doesn't seem to match it...

gregor@raspberrypi:~ $ ls
bridge  navidrome  seed  traefik
gregor@raspberrypi:~ $ ls *.*
ls: cannot access '*.*': No such file or directory
gregor@raspberrypi:~ $ cat *.*
cat: '*.*': No such file or directory

Right, so then if asterisk wildcards don’t match on . and .. then, in most common distros where there is no dot in any of the top level dirs in /, “rm -rf *.*” in the top level / dir is basically harmless and likely a noop.

So OP is wrong.
