Since I am using the Zsh as default Shell on my Linux machines but not all of them are Gentoo based, I put the Gentoo prompt here.

Just put the following lines to your .zshrc and you will be able to use this prompt on all distributions, not only Gentoo. Shure, I could copy the prompt file to the default directory in /usr/share/zsh/... but it is easier to just copy the .zshrc file from system to system...:

prompt_gentoo_setup () {
prompt_gentoo_prompt=${1:-'blue'}
prompt_gentoo_user=${2:-'green'}
prompt_gentoo_root=${3:-'red'}

if [ "$USER" = 'root' ]
then
base_prompt="%B%F{$prompt_gentoo_root}%m%k "
else
base_prompt="%B%F{$prompt_gentoo_user}%n@%m%k "
fi
post_prompt="%b%f%k"

#setopt noxtrace localoptions

path_prompt="%B%F{$prompt_gentoo_prompt}%1~"
PS1="$base_prompt$path_prompt %# $post_prompt"
PS2="$base_prompt$path_prompt %_> $post_prompt"
PS3="$base_prompt$path_prompt ?# $post_prompt"
}

prompt_gentoo_setup "$@"
