当我运行以下命令时：
# apt-get purge unity-scopes-m*
我希望它删除以下包：
unity-scope-manpages
unity-scope-musicstores
unity-scope-musique
相反，它想要清除大量我没想到的包：

为什么该命令吞噬的软件包比我预期的要多得多？根据apt-get手册：
.如果没有包与给定表达式匹配，并且该表达式包含,?或者之一*，则假定它是 POSIX 正则表达式，并将其应用于数据库中的所有包名称。然后安装（或删除）所有匹配项。
我的当前目录中没有文件导致 Bash 展开*，即使我放入unity-scope-m*单引号也会发生同样的问题。
答案1
附加包很可能是您希望删除的主包的依赖项。
您确定这些是唯一与该字符串模式匹配的软件包吗？检查：
rpm -qa | grep unity-scopes-m
