Storytime

Fortune-teller cow wasn't known for her milk production,

but for her uncanny ability to see the future.

Farmers flocked to her pasture, eagerly awaiting a swish of her tail

(left meant sunshine, right meant rain).

Installation

Install fortune and cowsay

First, you need to ensure that both fortune and cowsay are installed on your system. You can do this using your package manager. For example, on Ubuntu or Debian-based systems, you can use apt:
```
sudo apt update
sudo apt install fortune cowsay
```
For other Linux distributions, you might use yum, dnf, or another package manager appropriate to your system.
Modify your .bashrc file

Once you have fortune and cowsay installed, you can modify your .bashrc file to display a random fortune each time you open a new terminal window or tab.

Open your .bashrc file in a text editor. You can do this with the following command:
```
nano ~/.bashrc
```
Scroll to the bottom of the file, and add the following lines:
```
# Display a random fortune with cowsay when opening a new terminal
if [ -x /usr/games/cowsay -a -x /usr/games/fortune ]; then
  fortune | cowsay
fi
```
Save the file by pressing Ctrl + O, then press Enter to confirm, and exit Nano by pressing Ctrl + X.
Test it out

Open a new terminal window or tab, and you should see a random fortune displayed in a speech bubble created by a cow! Each time you open a new terminal, you'll see a different fortune.

That's it! You've successfully installed fortune and cowsay on your Bash shell and configured it to display a random fortune each time you open a new terminal session.
