https://askubuntu.com/questions/128524/how-to-list-dependent-packages-reverse-dependency建议apt-cache rdepends但不解释如何解释输出。输出由没有缩进和两个空格的行组成。但是依赖关系形成了树线结构，有什么方法可以这样查看输出吗？如何解释没有树？例如：
我跑：
~$ apt-cache rdepends --recurse --no-recommends --no-suggests --no-conflicts --no-breaks --no-replaces --no-enhances libpulse0:i386
得到约 1k 行（仅--recurse选项输出为约 500k 行）。第 300 行左右（最后完整输出）：
...
Reverse Depends:

libespeak-ng1:i386
libcanberra-pulse:i386
Reverse Depends:
pulseaudio
Reverse Depends:
pulseaudio-module-bluetooth
pulseaudio-module-bluetooth
...
在此之前我没有注意到列出的非 i386 软件包，所以第一个是pulseaudio.如何找出需要哪个包pulseaudio？前一行的缩进与前一次不同， 没有缩进libcanberra-pulse:i386。是libcanberra-pulse:i386需要的意思吗pulseaudio？下面的输出apt-cache show将其列为依赖项，但输出apt-cache rdepends未列出其他依赖项，例如libc6。

您可以使用apt-rdepends'--dotty或--xvcg选项生成图形输出；它输出的信息可以使用其他工具进行后处理，以生成节点和边缘表示（让人想起树或灌木）。
文本输出显示每个包（未缩进），然后显示其反向依赖项（缩进）。该--recurse标志也会导致每个反向依赖项被处理。 X 的反向依赖是一个包 Y，其中 Y 依赖于 X，这与显示的相反apt show。
要找出哪些包需要pulseaudio，请查看紧随其后的反向依赖项列表：
