RPM

features

  • Dependency tracking: 의존성을 tracking
  • installed file tracking

options

  • rpm -i : installing
  • -V 패키지명
  • -Uvh 이름.rpm : installing + Upgrading (vh -> 설치 과정을 화면에 표시)
  • -e 패키지명 : 삭제
  • -ql 패키지명 :
  • -qf 파일의절대경로 : 파일의 절대경로로 설치
  • --nodeps : 삭제할 때 의존성 관계 갖고 있는 패키지 중에 특정것만 삭제하겠다.
  • --force : 강제로 설치

단점

rpm dependency(의존성)에 대한 문제는 알려만 주고, 처리는 사용자가 알아서 해야 함.
=> 이러한 단점을 보완하여 나온 것이 yum !
