Fake directory cleaning script. Scare users, have a few laughs. Just add 'source /path/to/bofh_cleaning.sh' to the users bashrc file.

bofh_cleaning.sh

#!/bin/bash

trap "touch $HOME/.bofh_interupted" SIGINT

echo "####################################################"
echo "# This is the home directory cleaning process.     #"
echo "####################################################"
echo

### Get their blood pumping...

echo "All files will be removed in 5 seconds."
echo "---"
counter=5
while [ $((counter)) -gt 0 ] ; do
    echo $counter
    sleep 1
    counter=$((counter - 1))
done
echo "---"

### Now scare them!!!

if ! [[ -f "$HOME/.bofh_done" ]] ; then
    for file in $(find .) ; do
        echo "REMOVING: $file"
    done
    echo
    if [[ -f "$HOME/.bofh_interupted" ]] ; then
        echo "Opps, my bad.  You tried to stop the cleaning."
        echo "This is awkward, your files are all gone."
        rm $HOME/.bofh_interupted
    else
        echo "Thank you for helping us free up addition space."
    fi
    
    touch $HOME/.bofh_done
    echo
else
    echo "Directory is empty.  Nothing to do"
fi
