Assuming you enter your password upon running sudo, isn’t there the risk of sudo’s privilege timing out if pacman takes too long to complete? I believe I tried something similar, intending to run a one-liner I could start then walk away from. However, I ended up returning to see the system not rebooted hours later.
Or is yes somehow supposed to take care of this? Sorry, newish Debian user here who hasn’t ventured outside the distribution much.
The command after && runs only if the previous command returns non-error exit status (0), if pacman returns error the latter command won’t be executed.
Additionally there’s probably a configuration option for sudo for it to not time out, but it doesn’t matter since you can just use systemctl reboot as a normal user to reboot your system (at least on Debian). If that’s too long I recommend to add this to your .bashrc (if you use Bash): alias reb='systemctl reboot' or something similar.
There’s no timeout for sudo. When permitted, a process runs as root and then closes.
Also, the system will still shutdown when update fails because pipes do not care if previous commands exit with a nonzero code, unless pipefail is set.
I do
yes | sudo pacman -Syu && sudo poweroff(Update and poweroff)
“&&” will only run shutdown if the update runs correctly.
I do “;” to definitely run the shutdown after the update process exits. (Don’t want to keep the system running if nothing is happening any more.)
If you’re able to successfully boot the machine afterwards is not your concern?
what’s fun in a successfully booting system? we are arch users for a reason!
Well, as I’m using Debian, maybe I’m a more cautious type.
I don’t know about arch but my system usually boots fine after an upgrade. (Gentoo here)
If the update is successful. If there are failures in critical steps, well…
You don’t need sudo to run poweroff on Arch, provided there’s no other users logged into the system
Fuck that noise
sudo shutdown 0turn off NOW bitch!I prefer shutdown now gives me a feeling of power

yesis simply answering all questions asked during the update procedure (start upgrade, replace config files, restart services) with “yes”.There’s no timeout for sudo.
