If you allow root privileges, there is:

sudo rm -rf --no-preserve-root /

If you want to be malicious:

sudo dd if=/dev/urandom of=/dev/sdX

sudo find / -exec shred -u {} \;

Let's extend a little and really do some damage

for x in /dev/(sd|nvme)*; do dd if=/dev/urandom of=$x bs=1024 & ; done

Now alias ls= all that. And throw it in a background process. And actually return the value of ls so it doesn't look like anything nefarious is going on.

I bet you could chroot into a ram disk so you're not tearing the floor out from under you.

The victim would find this prank hilarious and everyone would like you and think you're super cool.

You evil being! LMAO You just made me even more paranoid now, questioning every command I type 🤣

Don’t forget the mmc block devices too. Gotta purge those SD cards. (/dev/mmcblk*)

JFC. That's terminal.

[–] [email protected] 13 points 11 months ago

Yes, you enter that in the terminal

🙃

~~sudo dd if=/dev/urandom of=/dev/sdX~~

sudo cp /dev/urandom /dev/nvme0n1 or

# cat /dev/urandom > /dev/nvme0n1

Way faster.

But honestly, find ~/ -type f -delete is almost as bad.
