Who hasn't typed a risky command? Throw the first stone!

DOS user detected! In linux you don’t need *.*, you can just use *

Maybe he wanted to remove only files with a dot in the name
Show threadjayboneMar 16
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.
Show threadLenaMar 16

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.

Technically, it says he’s in the ~ directory, which would usually be /home/god, but even in there there aren’t usually any directories/files with a dot.
Show threadpsudMar 20
~ has many dot directories and files
Show threadLenaMar 21
Oh yeah nevermind I’m an idiot
Show threadprettybunnysMar 16
well, depending on your shell
Show threaddb0Mar 16
Which shell interprets * as everything before extension?
Show threadprettybunnysMar 16

Well I’m not necessarily commenting on the *.* but * will skip .files in bash.

Show threaddb0Mar 16
I think *. * also skips them
Show threadprettybunnysMar 17

*.* will likely expect a file named *. and then delete any file globbed, but still leave dotfiles. At least in bash.

In my shell it would just error at me and be mad fish doesn’t work like ‘bash` in this specific case

This explains a lot.

Going to point out that not only is . unnecessary, but he’s in ~ (home) so assuming it even worked he just deleted his home.
Show threadScrathMar 16
Well, guess that’s it for heaven
Show threadthe rizzlerMar 16
maybe his $PS1 just happens to have a tilde in it
