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。

如何获得所有Dpkg::Options及其当前设置值的列表？

不幸的是，apt-config dump没有列出您要查找的dpkg选项。man dpkg帮助我找到了该命令，该命令--force-help更特定于force您感兴趣的特定dpkg 选项，但没有完整的选项列表：

$ 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>,...

  [!] 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
  [!] confmiss           Always install missing config files

可以完成使用。

apt-config dump

简短答案： dpkg --force-help

我不同意接受的答案。尽管apt-config dump可帮助查看一些当前启用的选项-其中许多通常对于简单的apt操作很有用-但它并没有显示dpkg操作的所有选项，即“强制”选项。原始问题参考。要查看默认情况下启用了这些附加选项中的哪些选项，以及仅应在有充分知识的用户完全必要时才更改哪些选项，必须使用（由CLI提供）提供的帮助dpkg --force-help。dpkg的手册页在描述--force-*things*该dpkg命令标志的部分下简要说明了该标志的输出。该手册页也可以在线查看：http : //man7.org/linux/man-pages/man1/dpkg.1.html https://linux.die.net/man/1/dpkg （这些只是几个位置）。
