i just run yay without args.

nix flake update && sudo nixod-rebuild switch

On Arch I don't need any, I just run paru without any options, which by default invokes a full Pacman update, as well as updating all AUR packages. But I have a system maintenance script, that, besides doing some other stuff that's specific to my system, runs paru -Sc --noconfirm to clean the Pacman package cache, and delete unneeded cloned AUR Git repos and build artifacts.

No alias, just topgrade

Using Bluefin (a Fedora atomic distro) and all of that gets done automatically behind the scenes. Flatpaks, distrobox containers, Brew, vocoder extensions, etc...

All done using topgrade: https://github.com/topgrade-rs/topgrade

Honestly, no. I just use direct apt commands on my Debian installs for native stuff, assuming I even use the shell for that; sometimes, if it's not a complex update that's going to hold back 1.0*10^6^ packages, I just use Synaptic or Package Updater, frankly, as one of those is what I have my XFCE Package Update Indicator set to use on any machine I use frequently and it's convenient sometimes.

As for Flatpaks, I just run the flatpak update command whenever I feel bored. I wish Warehouse GUI supported updating, just because I find it really weird that's excluded from an otherwise pretty slick application that gets rid of me having to muck through the Flathub.

I don't write Rust code at the moment, and as for Python, I'm either using the Debian version of Python packages or scattered venvs that follow a de facto standard for Python developers: "What's an update?"

The Mint upgrade tool got flatpak support so I don't even use the terminal to update anymore.

Topgrade handles most distros package managers, things like npm, brew and cargo, can pull git repositories and cleanup cache as well

#!/usr/bin/env bash
        systemctl --failed -q
        yay -Pw
        sudo reflector --save /etc/pacman.d/mirrorlist -c de -p "https" --ipv6 --completion-percent 100 -l 10 --sort age
        yay -Syu
        pacman -Qqnte > ~/.local/share/applications/pkglist.txt
        pacman -Qqdtt > ~/.local/share/applications/optdeplist.txt
        pacman -Qqem > ~/.local/share/applications/foreignpkglist.txt
        yay -Sc > /dev/null
        pacman -Qtd
        pacman -Qm
        sudo find /etc -name *.pac*

doas apk -iU upgrade

I actually just run the update commands individually when I feel like.

su -l 'pacman -Syu'  # All regular packages
pakku -Syu           # All AUR packages (I know this updates regular packages, too.)
flatpak-update       # Update Flatpak packages with a function I wrote

Since I do not trust Flatpak (especially when it comes to driver updates and properly removing unused crap) I once created this monstrosity.

flatpak-update () { 
    LATEST_NVIDIA=$(flatpak list | grep "GL.nvidia" | cut -f2 | cut -d '.' -f5)
    flatpak update
    flatpak remove --unused --delete-data
    flatpak list | grep org.freedesktop.Platform.GL32.nvidia- | cut -f2 | grep -v "$LATEST_NVIDIA" | xargs -o flatpak uninstall
    flatpak repair
    flatpak update
}

The initial problem with Flatpak thinking it would be a good idea to add dozens of Nvidia drivers and re-download and update all of them on every update (causing a few gigabytes of downloaded files on every run of a normal flatpak update even if nothing needed to be updated) is reportedly fixed, but I just got used to my command.

I don't use an alias, as the command to update is pretty small to begin with.

Yeah mine is less beautiful but

alias off='shutdown -h now'
alias update='flatpak update -y ; flatpak remove --unused --delete-data -y ; distrobox upgrade --all ; rpm-ostree update'
alias upfin='update ; off'

My firmware is write-protected so fwupd is not in there.

I don't, because stuff like that is a little too touchy to wrap in a cute shell alias. If I'm going to update a box, I'm going to update a box. If I'm going to reboot a machine, I want to be reminded that I'm going to reboot a machine (which in turn is a reminder that there are other people using stuff there and not to fuck their days up without at least a little warning).

I made a shell script titled "update", it updates system packages, flatpaks and python packages. Too many lines for an alias for my tastes.

I am a former openSUSE user, so my alias is: dup. It just refers to ujust-update, as Aurora is my current daily-driver.

My hot tip: initial capital so that your aliases are just a capital letter + tab away. Cache cleanup, update and Bleachbit:

alias Päivi='sudo pacman -Suy --noconfirm'

alias Siivous='sudo pacman -Sc --noconfirm;sudo pacman -Rns --noconfirm $(sudo pacman -Qtdq)'

alias SuurSiivous='sudo bleachbit -c system.trash system.ro tated_logs system.localizations java.cache journald.clean b ash.history'
