Como colorir “root” em vermelho no CentOS?

Este é o conteúdo de / etc / bashrc, gostaria de modificá-lo para mostrar "root" como vermelho, mas não sei onde adicionar o código de cor.

No Debian eu faço isso nesta linha:
PS1='${debian_chroot:+($debian_chroot)}\[3[01;32m\]\u\[3[00;37m\]@\[3[01;34m\]\h\[3[01;37m\]:\[3[01;36m\]\w\[3[01;35m\]\$\[3[00m\] ' mas no CentOS não faz ideia.

edit: Também estou pensando que talvez a edição desse arquivo tenha efeito tanto no usuário normal quanto no usuário root. Mas olhando nos detalhes .bashrc eles apontam apenas para / etc / bashrc.

Você precisará brincar com as cores, mas algo assim deve fazer o truque. Crie o arquivo /etc/profile.d/colours.sh com um conteúdo semelhante a este:

#!/bin/bash
if [ $(id -u) -eq 0 >/dev/null  2>&1 ]; then
  export PS1="\[3[01;32m\]\u\[3[00;37m\]@\h:\w\$ "
fi

Adicione em ~/.bashrc

 export PS1='\[\e[31;1m\]\h\w # \[\e[0m\]'

Eu adicionei esta linha ao meu ~/.bash_profile em uma Mac OSX Sierra. Seria ~/.bashrc no Ubuntu.

export SUDO_PS1="\[\e[31;1m\]$PS1\[\e[0m\]"
