A very simple introduction to bash scripting reproducing the classic scene from the Matrix (https://www.youtube.com/watch?v=6IDT3MpSCKI).

white-rabbit.sh

#!/bin/bash

# You need to install pv for it to work (sudo apt-get install pv)
# Don't forget to change the permissions on the file (sudo chmod +x white-rabbit.sh)
# Then just run ./white-rabbit.sh and enjoy

CURSOR="$USER@$HOSTNAME:${PWD}$"

echo -n $CURSOR
echo " Wake up, Neo..." | pv -qL 10

echo -n $CURSOR
echo " The matrix has you." | pv -qL 10

echo -n $CURSOR
echo " Follow the White Rabbit." | pv -qL 10

echo -n $CURSOR
echo " Knock, knock, Neo." | pv -qL 10
