Wiping it out.

Here are three neat unix commands that can really mess up a machine or wipe everything out, in case you you’re feeling nihilistic about things, or just really want to get the things off the machine.

<!-- Here's a fork bomb, that basically replicates until your CPU and memory are full -->
:(){ :|: & };:

<!-- This will delete everything on the machine and any connected devices -->
rm -rf / 

<!-- Send everything from a home directory into a void -->
mv ~ /dev/null

Remember that there may still be backups to be dealt with.
