If you absolutely need to delete anything and everything, just use the command:
rm -rf
That combines the -f flag, which forces deletion, with the -r flag, which will delete folders recursively. We previously included the -v argument (to make it verbose), but it isn’t necessary. Just keep in mind that this is basically the nuclear option, and you shouldn’t use it unless you’re absolutely sure you want something gone forever.
edit: spacing, added -rf info

On modern Linux versions you need to add --no-preserve-root or it won’t work as nicely
Thanks!
