Save list to file? (Y/n)
如你所见，我的系统中有 47 个专有软件包。就像我说的那样，我们可以将它保存到文件中稍后查看。为此，当提示你将列表保存在文件时，请按 y。然后按 y 接受默认值，或按 n 以你喜欢的格式和位置来保存它。
Save list to file? (Y/n) y
Save as markdown table? (Y/n) y
Save it to (/tmp/tmpkuky_082.md): y
The list is saved at /home/sk/absolutely-proprietary/y.md
You can review it from the command line
using the "less -S /home/sk/absolutely-proprietary/y.md"
or, if installed, the "most /home/sk/absolutely-proprietary/y.md" commands
你可能已经注意到，我只有 nonfree 包。它还会显示另外两种类型的软件包，例如 semifree、 uses-nonfree。
- nonfree：这个软件包是公然的非自由软件。
- semifree：这个软件包大部分是自由的，但包含一些非自由软件。
- uses-nonfree：这个软件包依赖、推荐或不恰当地与其他自由软件或服务集成。
该使用程序的另一个显著特点是它不仅显示了专有软件包，而且还显示这些包的替代品。
希望这有些帮助。我很快就会在这里提供另一份有用的指南。敬请关注！
干杯!
