獲取某些包使用了多少空間

我想知道我的 LaTeX 安裝使用了多少空間。我試著做，apt但我不確定這是否可能。我想做的是有一個類似的命令

apt-cache list --show-install-size texlive*

輸出

128 MB

當然show-install-size不存在。

Per binarysta 的評論，dpkg-query適用於已安裝的軟體包。如果您在安裝軟體包之前考慮大小，您可以使用apt或apt-cache.

apt show. 或apt-cache show給出一個Installed-Size:欄位

The TeX Live software distribution offers a complete TeX system. It

and font libraries. . This metapackage provides a decent selection of the
TeX Live packages which should suffice for the most common tasks. . The
distribution also includes extensive general documentation about TeX, as
well as the documentation accompanying the included software packages.

你可以：

$ apt-cache show texlive | grep Installed-Size
Installed-Size: 72.7 kB

或為texlive*：

$ apt-cache show texlive* | grep -E 'Package:|Installed-Size:'

來自man apt(8)：
