如何显示所有 apt-get Dpkg::Options 及其当前值？

有

apt-get -o Dpkg::Options::="--force-confnew"

和

apt-get -o Dpkg::Options::="--force-confold"

还有很多。

我如何获取所有列表Dpkg::Options及其当前设置的值？

不幸的是，apt-config dump没有列出您正在寻找的 dpkg 选项。man dpkg帮助我找到了这个命令，--force-help它更具体地针对force您感兴趣的特定 dpkg 选项，但不是完整的选项列表：

$ dpkg --force-help
dpkg forcing options - control behaviour when problems found:
  warn but continue:  --force-<thing>,<thing>,...
  stop with error:    --refuse-<thing>,<thing>,... | --no-force-<thing>,...
 Forcing things:
  [!] all                Set all force options

  [!] confdef            Use the default option for new config files if one
                         is available, don't prompt. If no default can be found,
                         you will be prompted unless one of the confold or
                         confnew options is also given

可以使用。

apt-config dump

简短回答： dpkg --force-help

我不同意接受的答案。虽然 apt-config dump 有助于查看一些当前启用的选项 - 其中许多选项通常用于简单的 apt 操作 - 但它不会显示 dpkg 操作的所有选项，即原始问题所指的“强制”选项。要查看默认情况下启用哪些附加选项，以及哪些选项应仅在完全必要时由知情用户更改，必须使用提供的帮助（来自 CLI） 。dpkg 的手册页在描述命令标志dpkg --force-help的部分下提供了此标志输出的简短说明。此手册页也可以在线查看： --force-*things*dpkghttp://man7.org/linux/man-pages/man1/dpkg.1.html https://linux.die.net/man/1/dpkg （这些只是几个地点）。
