apt-get remove -y 和 apt-get purge -y 之间有区别吗？

apt-get remove -y 和 apt-get purge -y 之间有区别吗？ 
apt-get remove <name of program>  

apt-get purge <name of program>

和

apt-get purge -y <name of program>

研究表明，运行“删除”或“清除”执行的功能完全相同，并且它们是可互换的命令。

运行该命令apt-get purge -y <name of program>将删除该程序及其依赖项。

换句话说，这个命令是否会删除与该程序严格关联的依赖项，或者是否会删除可能导致其他程序停止工作共享依赖项？

我应该运行哪一个来删除程序？purge或purge -y？

答案1

apt-get remove删除有问题的包

apt-get purge等同于apt-get remove --purge并将删除用户数据/配置文件。

从man apt-get：

   purge
       purge is identical to remove except that packages are removed and purged (any configuration files are deleted too).

和

   --purge
       Use purge instead of remove for anything that would be removed. An asterisk ("*") will be displayed next to packages which are scheduled to be purged.  remove --purge is equivalent to the purge command. Configuration Item: APT::Get::Purge.

该-y标志指示命令继续执行，而无需确认琐碎的问题。再次引用man apt-get：

   -y, --yes, --assume-yes
       Automatic yes to prompts; assume "yes" as answer to all prompts and run non-interactively. If an undesirable situation, such as changing a held package, trying to install a unauthenticated package or removing an essential package occurs then apt-get will abort. Configuration Item: APT::Get::Assume-Yes.

的手册页apt-get包含以下信息 -

   remove
       remove is identical to install except that packages are removed
       instead of installed. Note that removing a package leaves its
       configuration files on the system. If a plus sign is appended to
       the package name (with no intervening space), the identified
       package will be installed instead of removed.

   purge
       purge is identical to remove except that packages are removed and
       purged (any configuration files are deleted too).

因此，如果您希望删除某个包的所有配置文件，则purge最好使用 。但是，如果您希望保留配置文件，remove则应使用 。

   -y, --yes, --assume-yes
       Automatic yes to prompts; assume "yes" as answer to all prompts and
       run non-interactively. If an undesirable situation, such as
       changing a held package, trying to install a unauthenticated
       package or removing an essential package occurs then apt-get will
       abort. Configuration Item: APT::Get::Assume-Yes.

该-y标志不会删除依赖项，而是跳过用户对删除包的确认，假定在 Y/N 提示中回答“是”。

要删除导致问题或不需要再次安装的软件包，最好的选择是 -

apt-get purge <packagename>

这是因为，如果应用程序的配置文件被修改并导致了错误，purge则会删除它们，从而使后续安装看起来像是全新安装。

注意：此purge选项不适用于在用户主文件夹中保存配置文件的软件包。请参阅这个答案了解更多详细信息。
