Old school linux terminal fun revisited. Random fortune quotes using random cowsay in Linux terminal

Normally all the guides using fortune and cowsay uses the default creatures (a.k.a Cow!) to show different quotes. There’s plenty of guides on that. However, I wanted to show a random creature saying different fortune quotes on my terminal.I could find random figment of instructions in different forums and decided to write a small guide on how to do it properly. Few lines of codes, and my Linux terminal becomes more alive!
