Save list to file? (Y/n)
如你所見，我的系統中有 47 個專有軟件包。就像我說的那樣，我們可以將它保存到文件中稍後查看。為此，當提示你將列表保存在文件時，請按 y。然後按 y 接受默認值，或按 n 以你喜歡的格式和位置來保存它。
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
你可能已經注意到，我只有 nonfree 包。它還會顯示另外兩種類型的軟件包，例如 semifree、 uses-nonfree。
- nonfree：這個軟件包是公然的非自由軟件。
- semifree：這個軟件包大部分是自由的，但包含一些非自由軟件。
- uses-nonfree：這個軟件包依賴、推薦或不恰當地與其他自由軟件或服務集成。
該使用程序的另一個顯著特點是它不僅顯示了專有軟件包，而且還顯示這些包的替代品。
希望這有些幫助。我很快就會在這裡提供另一份有用的指南。敬請關注！
乾杯!
