在 Linux mint 上运行 gnome-terminal，一些自动完成功能自安装以来一直无法工作。有趣的是，像apt itabinsertsapt install和apt utabshown这样的命令unhold update upgrade按预期进行。同样，apt install wgtab显示wgaelic wgalician-minimos wgerman-medical wget wget2 wget2-dev.
然而apt list --itab 才不是自动完成 to apt list --installed，这就是我想要的。
所以，我认为问题出在我的/usr/share/bash-completion/completions/apt文件上，如下所示：
# Debian apt(8) completion -*- shell-script -*-
_apt()

其他所有内容似乎来源正确，我尝试取消注释

在两者中/etc/bash.bashrc，但这~/.bashrc也没有解决问题。

只需查看行为并推断功能即可。
apt somecommand --得到完成而不是apt --, whileapt-get --有效。原因是apt合并了不同命令的功能，其中apt-get和apt-cache。完成取决于子命令，因此选项应该出现在子命令之后是有意义的。
例子：
$ apt install --
--allow-change-held-packages --install-recommends
--allow-downgrades --install-suggests
--allow-insecure-repositories --no-install-recommends
--allow-remove-essential --no-install-suggests
--allow-unauthenticated --only-upgrade
--arch-only --print-uris
--assume-no --purge
--assume-yes --reinstall
--auto-remove --remove
--download --show-progress
--download-only --show-upgraded
--dry-run --simulate
--fix-broken --solver
--fix-missing --target-release
--fix-policy --trivial-only
--force-yes --upgrade
--ignore-hold --verbose-versions
--ignore-missing
但：
$ apt search --
--full --names-only
