보기에는 좋지만 더 많은 제어가 필요합니다. 예를 들어 호스트 이름이라고 생각되는 것을 숨기고 싶고 Vultr-Ubuntu14-Tokyo, 각 로그 줄 사이에 빈 줄을 넣어 더 느슨하고 보기 좋게 보이도록 하고 싶고, 색상도 변경하고 싶습니다. 각 명령 등

아래와 같이 Ubuntu에서 색상과 위치 및 기타 여러 가지를 사용자 정의 할 수 있었던 것으로 기억하여 PS1Linux(ubuntu) 로그에 대해 유사한 작업을 수행하는 방법이 궁금했습니다.

export PS1="
$BBlue[\h] $BBlue\t $BBlue\u No.$BBlue\# -> $BBlue\w$Color_Off
\$ "

감사해요.
