alias atp-get='sudo chmod 000 /;'

So, is your victim writes sudo apt-get it will do sudo sudo chmod?

Fail

How about:
sudo rm -rf $(sudo find / | shuf -n$(echo "$RANDOM 500 / p" | dc))
It deletes a random number of files/directories. Partial credits to devnull-as-a-service.

Add a -R to chmod 😆

dd if=/dev/null of=/dev/sda 😆

Was the 'atp' typo on purpose to punish typos?

I feel like its an evil command that will eventually happen.

gladly I use apt ;)

@Linux
probably

sudo sudo chmod 0000 install program

so it would probably error anyways

@Haxk20 yeah or filling it out with zero or ones with dd :P

Not kidding, I did sudo chmod -R 777 / once. iirc I did it because I was frustrated that I didn't have permissions by default in certain places so I thought that'd be the easy fix. What makes it less embarrassing is that is was also my first Linux install. Slowly things stopped working and I was confused as to why so I tried to restart it and that was the end of it, no more booting.

I dont understand the concept to well apparently. I only use chmod 755 on making a perl or c++ program. I dont understand how 777 would crash a person's system.

@dom3mo Linux is very strict when it comes to file permissions on system files...chmod 777 / gives everyone access to every single file so Linux says Nah f u I am out :)

@SHA-256 Creepy it happens gradually.
