Excuse me, but that type of foolishness requires -- no-preserve-root nowadays

[-] narshee@iusearchlinux.fyi 21 points 10 months ago

Not in this case. It's */ here so it expands to directories at current location. I'm sure that's a typo though

I'm not brave enough to test it on my distro, so I'll take your word on that lol

[-] narshee@iusearchlinux.fyi 12 points 10 months ago

You can do echo */ and echo /* to see how they expand. Also rm -rf / already is enough without the * as it already is recursive

* is there to bypass the need for --no-preserve-root

rm -rf / needs --no-preserve-root on GNU coreutils, I think.

why do they even have that lever

Originally, rm would merrily nuke your whole filesystem if you told it to. At some point, someone thought that was a pretty stupid default behaviour, so they added that flag to change the default to not nuke your entire filesystem. However, they made the change backwards compatible in case someone still needed the old behaviour. I can imagine in a container or throwaway environment, it might be vaguely reasonable to expect to be able the blat /.

I'm aware of how recursive force remove works. I'm just kidding around.

Anybody brave enough to tell the MS rep this on patch night??
