DEBIAN_FRONTEND 환경 변수

잠재적 인 호스팅 제공 업체 는 KVM 기반 서버의 OS 이미지를 최소화하기 위해 터미널에서 명령을 실행할 것을 제안 합니다. KVM 템플릿에는 패키지가 포함되어 있지 않기 때문에 필요하지 않은 패키지를 제거하기 위해 동일한 명령을 사용할 수 있다고 생각했습니다.

이 명령은로 시작하여 다음과 같이 DEBIAN_FRONTEND=noninteractive호출하십시오 apt-get remove.

DEBIAN_FRONTEND=noninteractive apt-get remove --purge -y -o Dpkg::Options::="--force-confdef" -o Dpkg::Options::="--force-confold" package-1 package-2 ... package-n; apt-get -y autoremove; apt-get clean all 

DEBIAN_FRONTEND환경 변수 가 처음으로 발견 되었으며 지금까지 유용한 정보를 찾을 수 없었습니다. 그래서 나는 그것이 무엇을 설정하는지 궁금하고 그것이 noninteractive가치가 있다면 그 가치 ( noninteractive)가 지속될 것이라고 가정하기 때문에 바람직하다면 .

apt명령을 앞에 추가 DEBIAN_FRONTEND=something해도 명령이 적용된 단일 명령 후에는 지속되지 않습니다.

DEBIAN_FRONTEND옵션의 제 7 매뉴얼 페이지에 설명되어 있습니다 debconf(당신은 설치해야 할 수 있습니다 debconf-doc시스템에이 사용할 수 있도록하기 위해 패키지). 보낸 사람 man 7 debconf:

Frontends
   One of debconf's unique features is that the interface it  presents  to
   you is only one of many, that can be swapped in at will. There are many
   debconf frontends available:

   dialog The default frontend, this uses  the  whiptail(1)  or  dialog(1)
          programs to display questions to you. It works in text mode.

   readline
          The  most  traditional frontend, this looks quite similar to how
          Debian configuration always has been:  a  series  of  questions,
          printed  out  at  the console using plain text, and prompts done
          using the readline library. It even supports tab completion. The
          libterm-readline-gnu-perl package is strongly recommended if you
          chose to use this frontend; the default readline module does not
          support  prompting  with default values.  At the minimum, you'll
          need the perl-modules package installed to use this frontend.

          This frontend has some special hotkeys. Pageup (or ctrl-u)  will
          go  back  to  the previous question (if that is supported by the
          package that is using debconf), and pagedown  (or  ctrl-v)  will
          skip forward to the next question.

          This is the best frontend for remote admin work over a slow con‐
          nection, or for those who are comfortable with unix.

   noninteractive
          This is the anti-frontend. It never interacts with you  at  all,
          and  makes  the  default  answers  be used for all questions. It
          might mail error messages to root, but that's it;  otherwise  it
          is  completely  silent  and  unobtrusive, a perfect frontend for
          automatic installs. If you are using this front-end, and require
          non-default  answers  to questions, you will need to preseed the
          debconf database; see the section below  on  Unattended  Package
          Installation for more details.

또한 다음 사항에 유의하십시오.

   You can change the default frontend debconf uses by reconfiguring  deb‐
   conf.  On the other hand, if you just want to change the frontend for a
   minute, you can set the DEBIAN_FRONTEND  environment  variable  to  the
   name of the frontend to use. For example:

     DEBIAN_FRONTEND=readline apt-get install slrn

   The  dpkg-reconfigure(8) and dpkg-preconfigure(8) commands also let you
   pass --frontend= to them, followed by the frontend  you  want  them  to
   use.

   Note  that not all frontends will work in all circumstances. If a fron‐
   tend fails to start up for some reason, debconf will print out  a  mes‐
   sage explaining why, and fall back to the next-most similar frontend.
