Perhaps someday somebody else does miss the forest for the trees, so here's the forest I found: yaourt -aQu linux-rt does check if there's an update for the linux-rt aur package :). Tested with: [rocketmouse@archlinux ~]$ yaourt -aQu git google-earth extra/git 1.8.3.2-1 aur/google-earth 7.1.1.1888-1 [installed: 7.1.1.1871-1] (1876) [rocketmouse@archlinux ~]$ pacman -S git --print --print-format %v 1.8.3.3-1 If there isn't an update the output does look like this: [rocketmouse@archlinux ~]$ yaourt -Qua linux-rt aur/linux-rt 3.8.13_rt14-1 [installed] (162) Special thanks to Gaetan for the hint to use "--print --print-format". I haven't written a script yet, but now all the needed information is available. Regards, Ralf
