[arch-general] Check for update in script
Hi I can't find a good way to check for available upgrades without touching the database, as running `pacman -Sy` without `u` isn't supported. Any idea ? Maybe a new pacman switch like "--upstreamdbpath" to toggle change the location of sync/ without touching local/ ? Why I need it : https://github.com/XavierBerger/RPi-Monitor/pull/57#issuecomment-55248969 Yamakaky

pacman provides a `checkupdates` script, see /usr/bin/checkupdates for how it works. -- jlk

Wow, I didn't know this one, thanks !

Yes, I know, but I never used this one.

It can certainly be done. You can always do a "pacman -Su" later, if you want. In your use case, you can probably specify an alternative db path using the --dbpath switch in pacman. In this case, I believe RTFM is an appropiate response. :) Hope it helps. -- Savyasachee Jha *"Aerodynamics is for people whodon't know how to build engines."*

The problem is that I want to check for updates in a script. 'pacman -Sy' without upgrade can cause problems.

That's what I wanted to do, but dbpath countains the local and upstream databases, so I thought it might cause problems.

If I understand it right, and correct me if I do not, you can use pacman -Syy --dbpath /tmp/pacman-update/, right? That way, if you want to check the local databases (currently installed and active), you can use pacman -Si <package-name> and if you want to check the latest ones, you can use pacman -Si --dbpath /tmp/pacman-update/ <package-name>. I think that this is the same mechanism as used by the check-updates script. That script just cleans up a bit more, but fundamentally uses this same switch. -- Savyasachee Jha *"Aerodynamics is for people whodon't know how to build engines."*
