MarsSeed [1] filed a deletion request for archupdate [2]: Trivial script from 2015 that shouldn't exist. The first two lines belong to a personal bashrc or shell .profile or so. The third line just executes pacmatic -Syu instead of pacman -Syu. The AUR helpers pacaur and pacmatic haven't been meaningfully updated in 4 and 7 years, respectively. So it's best to delete this obsolete and unnecessary script. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/archupdate/
