우분투(Ubuntu)에서 패키지를 관리하는 명령어가 몇가지 있습니다. 그 중 가장 기본이 되는 것이 apt-get입니다. 많은 옵션이 있는데, 자주 쓰는 몇가지를 정리해보겠습니다.apt-get update

패키지 목록을 갱신합니다.

apt-get upgrade

모든 패키지를 최신 버전으로 업그레이드합니다.

apt-get install abc

abc 패키지를 설치합니다.

apt-get remove abc

abc 패키지를 삭제합니다. 설정파일은 삭제하지 않습니다.

apt-get purge abc

abc 패키지를 삭제합니다. remove와 다르게 설정파일도 삭제합니다.

참고로 패키지 검색은 apt-cache로 합니다. abc를 포함한 패키지를 검색하려면 

apt-cache search abc

와 같이 하면 됩니다.
