Apesar do link acima, achei por bem colocar o passo a passo aqui também.
1 – Salve o código no final deste post com o nome de .zer0prompt no seu diretório home.
2 – edite o arquivo .bashrc, comentando a linha PS1 e insira o código a seguir:
source ~/.zer0prompt
zer0prompt
unset zer0prompt
Código do arquivo .zer0prompt:
