Display a colourful quote on login

Run the usual apt install for:


Put the following at the end of .bashrc, because it’s only run for interactive shells:

# print a friendly fortune on login
if [ -x /usr/games/fortune -a -x /usr/games/cowsay -a /usr/games/lolcat ]; then
    fortune | cowsay | lolcat
