Hi,
In CentOS6  I do:
echo "savedefault --default=0 --once" | grub --batch

My question is how do I do the same on CentOS7?
Any ideas?

C7 uses grub2:

look at the man-pages of these:
 grub2-set-default
 grub2-editenv
 grub2-reboot
 grub2-once

Either grub2-set-default or direct via grub2-reboot
with the needed params.
