A Very Emotional Bash Prompt
This is just something I randomly threw together one day cuz I thought it would be funny if the bash prompt was a little more emotional over it's exit codes. This will look good in most terminals with a basic font like 'monospace' as well as some options here for 'cool-retro-term' with TERM set to 'xterm-256color'.

nano -w ~/.bashrc
For the sake of an example, this will load the prompt into the current user's .bashrc login script.

Save this example somewhere. This script example can be loaded however you want, globally through the bashrc.d, bash.bashrc (or system-a-like situation), your ~/.bashrc or whatever. It just needs to execute it before you finish logging in, preferably somewhere at the end so other PS1 variables elsewhere don't overwrite this behaviour. This prompt is the same colours I use myself, however it's easy to figure out what to use to customize this so you can suit your needs or uncomment one of the presets in the rainbow function and customize the predefined colors in this script using the variables like '${NEONAPPLE}'.
#!/bin/bash
for i in {1..255} ;
do
printf "\x1b[38;5;%sm%3d\e[0m " "$i" "$i";
if (( i == 15 )) || (( i > 15 )) && (( (i-15) % 15 == 0 )); then
printf "\n";
fi;
done
Here you'll get a print out of all the 256 colour range you can use and their codes. Since we're using xterm-256color capable colours we will have to pay attention to the main method of printing these colours. Every colour of this foreground setting will start with \e[38;5; so \e[38;5;201m would be a hot pink and in bash it would print \001\e[38;5;201m\002 so we can bypass a bash bug that makes the formating be undesirable. As shown in the script above you will need to pass the '-e' switch with an echo command to parse these escape sequences. You may also use the PREDEFINED colors in the bashrc script at the bottom.

This is a preset you can import into cool-retro-term. Bear in mind some photo examples may have had modifications since.
