Check for updates of packages installed through yaourt

Question

Is there anyway to update package installed with yaourt ? yaourt -Syu seems to do the same as pacman -Syu, which only care about package in official repository.

Answer 1

You can update your system including AUR packages with:

yaourt -Syua

https://wiki.archlinux.org/index.php/Yaourt

Answer 2

If you had read the manual pages:

$man yaourt

You would have seen an entry like this:

-a, --aur
    Also search in AUR database. With -u or --sysupgrade, upgrade aur
    packages that are out of date. With -Qm, display more info about
    foreign package.

In fact you'll find many other options in the man pages for things yaourt can do but pacman cannot. pacman was built keeping in mind the Arch Way.
