pacman sort packages

Is there an option to sort packages via installation date ?

i can see all the details with

pacman -Qi

but i cant find a way to sort them up

In a paranoid moment i wrote this:

pacman -Qi | grep -E '^Name|^Install Date' | awk -F":" '{print $2}' | sed '0~1s/$/ - /g' | sed '0~2s/ - $/#/g' | tr '\n' ' ' | sed 's/#/\n/g' | sort -k2 -d

Pacman doesn't have any built in sorting option that I know of. But that's why we have creative bash scripting as you did

So the right way, is to open a bug feature request.

You can try. Allan likes to keep things as simple as possible.

I don't reject all ideas (that is Dan's job), but that one might be very low on my willingness to include scale

Look into whether expac can do this...

Hey /dev/zero, try not to blank what you've previously written, its bad manners . Not that it matters very much in this case, but unless the code you previously put up there was machine-killing, no real reason to remove it.

Install pyalpm to use this. It will print the installed packaged sorted by installation date.

#!/usr/bin/env python3
from pycman.config import init_with_config

h = init_with_config("/etc/pacman.conf")
for p in sorted(h.get_localdb().pkgcache, key=lambda x: x.installdate):
  print(p.name)

Either edit the loop to print more info directly, or pass the output to pacman to use the standard output format:

pacman -Qi $(./script.py)

I apologise. It was broken. I'd like a chance to fix it, but it was too late at night to do it straight away.

Okay, I have something that seems to work okay. It outputs the same information, but I'd argue the underlying code is a bit nicer. It's structured in a more logical way that should make it easier to modify, eg with additional fields from "pacman -Qi".

#! /bin/bash
function pacfield() {
    pacman -Qi | awk -vF="$@" -F':' 'BEGIN{p="^"F} $0~p{print $2}'
}
pr -tm <(pacfield Name) <(date --file=<(pacfield "Install Date") +%F) | sort -k2 -d
