Docker-安装完整Ubuntu
在 Docker 里的 Ubuntu 使用 man 命令时，总是提示：
This system has been minimized by removing packages and content that are
not required on a system that users do not log into.
To restore this content, including manpages, you can run the 'unminimize'
command. You will still need to ensure the 'man-db' package is installed.
而输入 Unminimize 命令又总是显示找不到该命令，翻来覆去找不到答案。最后看到了一篇博客(贴在文末了)。其实并不是每个 ubuntu 版本都有这个 unminimize，所以把这个脚本贴出来了。
脚本位于 /usr/local/sbin/unminimize。

虽然这个脚本还是没解决我的问题……
