BASH – .bash_profile – Custom Login Message with Colours

Hey all,

I have made a few customisations to my dedicated server over the years, one of which is a custom login message with a full coloured display.

I have posted the code below for you all to inspect and use at your own discretion.

Have fun all!

Custom .bash_profile

# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
