Sudoers

pacman -S sudo

Use sed to uncomment the wheel group from sudoers, then hijack the EDITOR variable to copy the modified version back via visudo.

sed 's/# %wheel ALL=(ALL) NOPASSWD: ALL/%wheel ALL=(ALL) NOPASSWD: ALL/g' /etc/sudoers > /etc/sudoers.new
EDITOR="cp /etc/sudoers.new" visudo
rm /etc/sudoers.new

Create a non-root user

useradd -m -g users -G wheel,audio -s /bin/bash usernme
passwd username

At this point logoff and login as user
