"When you log in on the console of your Linux System, you are
usually presented with a login screen with info about the system
you are about to log in on. In this short article I will show
you how to change what you see on your login screen, and also how
to add a bit of colour."
"When your Linux System boots it starts "getty" processes on a
number of virtual terminals on your system. When getty starts, it
prints the contents of /etc/issue to the terminal. To customize the
look of your console, all you have to do is edit /etc/issue."
"You can also add colour by using the colour capabilities of the
Linux console. The Linux console, like almost any other existing
terminal, has escape sequences that can be used to change the
appearance of text on screen."
