I've never actually tried this but feel like rm should have a built in warning specifically for that command letting them know they've been trolled and have a y/N prompt.
There kind of is one, but it is overridden by -f
You also need the flag "--no-preserve-root".
No you don't.
rm -fr /requires the flag, butrm -fr /*does not.I think that is only if you pass
/, I don't think the flag is required for/*which is what is shown here - if I remember right, it's because the*triggers the shell to expand the paths and that flag is only built to protect/(from say, having an empty variable alongside/).Yes, the * is expanded by the shell so the rm command just sees lots of individual files being passed in
Come on, it is super fun. Just install VirtualBox and set up a virtual machine, make sure there is no funky mount point that touches your host machine, and go nuke that VM !
You can create an alias in ".bashrc" just in case.
