Careful, you have to also add
--no-preserve-rootto make sure you get all of it out. If you leave the roots, it'll just grow back later!(But seriously, don't actually do this unless you're prepared to lose data and potentially even brick your computer. Don't even try it on a VM or a computer you're planning to wipe anyway, because if something is mounted that you don't expect, you'll wipe that too. On older Linux kernels, EFI variables were mounted as writable, so running
rm -rf /could actually brick your computer. This shouldn't still be the case, but I wouldn't test it, myself.)Fun fact, rm -rf /* does not need --no-preserve-root. It will happily start as technically, according to the preserve root check, /* is not root as the target is not /
It's slightly different. Your shell will see the
/*and replace it with all the directories under /, e.g./bin /dev /etc /homeetc. So the actual command that runs isrm -rf /bin /dev /etc /homeetc.

Oh my god I effin guffawed, thanks for that
I ran it in Hyper-V once to see what happens and it deletes all the boot entries from the VM firmware (including pxe boot and the dvd drive)
