根據dpkg-query手冊頁：
例如，這將列出以“libc6”開頭的所有套件名稱：
dpkg-query -l 'libc6*'
當我在 Debian 10.5 上嘗試：
$ dpkg-query -l 'libc6*'

如何讓dpkg-query顯示所有符合項目？為什麼它只顯示一個選擇？
答案1
dpkg-query僅預設查看/var/lib/dpkg/status，並且僅包含有關當前安裝或過去安裝的軟體包的資訊。
若要查看所有可用的軟體包，您可以新增以下--load-avail選項：
dpkg-query --load-avail -l 'libc6*'
但這依賴/var/lib/dpkg/available與時俱進。apt不觸及該文件，它使用自己的資料庫，因此您需要自己處理：
for file in /var/lib/apt/lists/*_Packages; do sudo dpkg --merge-avail $file; done
（請注意，這不考慮翻譯的描述，因此dpkg-query無法顯示它們。）
最好用於apt此類查詢。dpkg具有套件的本機視圖，apt具有基於儲存庫的視圖；因此基於儲存庫的查詢最好由apt.
