using the files in /var/lib/apt/lists/ directly should be avoided because the
naming scheme can change arbitrarily and the files might be compressed. You
should use "apt-get indextargets" instead.
Also, instead of awk, you might want to use grep-dctrl instead.
So the first part above until the sort would become:
apt-get indextargets \
| grep-dctrl -s Filename -n \
-F Created-By Packages \
-a -F Suite unstable \
-a -F Component main \
-a -F Architecture amd64 \
| xargs /usr/lib/apt/apt-helper cat-file \
| grep-dctrl -n -sPackage,Installed-Size,Size -FInstalled-Size '' \
| paste -sd " \n" \
| sort ...
One can avoid the first grep-dctrl call by using "apt-get indextargets" command
line options like so:
apt-get indextargets \
--format '$(FILENAME)' \
"Created-By: Packages" \
"Suite: unstable" \
"Component: main" \
"Architecture: amd64" \
| xargs ...
I just personally like to use grep-dctrl because then I don't have to learn yet
another syntax of how to filter deb822 files.
Thanks!
