How to Make Ascii Art Login Banner

If you are interested in making something like the above, 
follow these steps.

Use an online ascii art generator to create your desired 
art and copy all of the characters to the clipboard.

Create a file and paste in the characters copied above 
and save the file.

Now run the following command and replace filename with the 
name of the file you created in the previous step. 
This will generate your login script.

ex.:
echo '#!/bin/bash'; while IFS= read -r line; do echo "echo '$line'"; done < filename > mymotd.sh

Now copy mymotd.sh to /etc/profile.d 

and make it executable.

sudo cp mymotd.sh /etc/profile.d/
sudo chmod +x /etc/profile.d/mymotd.sh

Now when you log in, you will see the banner in your 
terminal. You can modify this file anyway you like.
