[SOLVED] Convert list /w '*.so' names and '*>=4.10' to repo pkg names

NuSkool · 2025-02-12 19:28:08

I have an nspawn container that I'd like to keep maintained with a particular set of packages including base, base-devel, and an AUR.
It has various uses mostly around building packages.

I have a bash script to clean it that removes all packages not in a 'list'.
This works well except over time, base and base-devel change the pkgs they install.

To work around this, I have a second bash script that creates a fresh 'list' as if I had just recreated the container.

Now onto the issue... The script used to calculate the fresh 'list' is a 70+ line embarrasing mess.

Part of the issue is converting the '*.so' names and '*>=4.10' versions into package names.
Is there a clean way to do this conversion or is this an 'A B' problem?

Here's part of the script:

	pactree -slu       base | sort -u				>  /tmp/acpl/acpl
	pactree -slu base-devel | sort -u				>> /tmp/acpl/acpl
	pactree -lu    aurutils | sort -u				>> /tmp/acpl/acpl

	sort -u /tmp/acpl/acpl  | awk -F'>|=|<' '{print $1}'		>  /tmp/acpl/acpl-pre

	awk -F"=" '/\.so/ {print $1}' /tmp/acpl/acpl-pre  		>  /tmp/acpl/so

	grep -v '\.so' /tmp/acpl/acpl-pre | xargs -n1 pacman -Qq	>  /tmp/acpl/acpl-pre1

	while read -r line
	do
		pacman -Fq "${line}" | head -n1 | awk -F"/" '{print $2}' 	>> /tmp/acpl/acpl-pre1

	done < /tmp/acpl/so

	sort -u /tmp/acpl/acpl-pre1 | nl | sudo tee $(pwd)/.#orig-pkgs.log-$(date '+%Y-%m-%d')-NEW

Uninstall all orphaned deps, uninstall all explicitly installed packages not names base, base-devel, or aurutils. Done.

Thanks Scimmia.

Trying to get my thick head around your reply....

So 'pacman -Qdtq' fed to pacman remove covers 'orphaned deps'.

uninstall all explicitly installed packages not names base, base-devel, or aurutils

Are you saying don't remove the pkg names, 'base', 'base-devel', 'aurutils'?

So 'pacman -Qqe' minus the package names 'base, base-devel, aurutils' fed to pacman remove?

That would remove all the packages base and base-devel install.

I have a bash script to clean it that removes all packages not in a 'list'.

EDIT: Maybe this would help clarify my question....

Is there a simple way to convert the following list into package names?
I realize pacman would install the packages revealing their names, but I don't want install.
I'm currently converting these into package names with my script, but looking for a cleaner, more accurate method.

That would remove all the packages base and base-devel install.

No, it wouldn't. They're metapackages, everything they depend on stays.

Edit: and yes, I understood your question, my point is that that's a terrible and needlessly complicated way to do it. This is very simple.

I was a little apprehensive to post the script, because I was SO FOCUSED ON there would be a much cleaner way to filter the list.
Well worth feeling a bit embarrassed to get rid of that whole script though, and to be replaced with just a few commands.
Not to mention get straightened out on some basic pacman usage.

pacman -Qdtq | pacman -Rns -
pacman -Qqe | grep -Ev 'base|base-devel|aurutils' | pacman -Rns -

I obviously never gave the pacman commands enough thought which caused a bad case of, "can't see the forest for the trees".

Thanks again and also for being persistent Scimmia!

EDIT: corrected the commands

Moving to Pacman issues by request.

By the way, you can use the built-in "Report" button on your own OP to request a move, in order to send a notification to all mods, so you don't have to rely on me checking my mail to see a request.
