我想将已安装程序的依赖项列表保存到文本文件中。我想要这样做的原因是，例如，如果我要安装一个元包，而该元包又依赖于其他几个包，而这些包不会因单独删除元包而被删除。
我知道我可以用以下方法做到：
sudo apt-get install kubuntu-desktop | tee log_file.txt
但这会保存命令的整个输出。我只想有一个包含已安装包和依赖项的列表，以便我可以使用此命令删除包和依赖项：
sudo apt remove $(cat log_file.txt)
我想这应该是可能的，只是超出了我对 Bash 和 shell 脚本的了解。所以如果能提供一些建议就好了。

使用apt-cache和awk
apt-cache showpkg kubuntu-desktop | awk '/Dependencies:/,/Provides:/ {for(i=1;i<NF;i++) {if(i%3==0) {print $i}}}' | tee log_file.txt
示例（带有ubuntu-desktop，抱歉）
% apt-cache showpkg ubuntu-desktop | awk '/Dependencies:/,/Provides:/ {for(i=1;i<NF;i++) {if(i%3==0) {print $i}}}' > out
% cat out
