how to update grub? i know on ubuntu update-grub2 , on mageia what command i can use for update grub?

Updates for grub, like for any other packages, are given available through Mageia's Control Centre.
That is, for if there are updates.
Grub2 will not be available before Mageia2, or earlier in Cauldron.

I guess he means the command which is needed in grub2 after changing anything in the menue.
This is not needed in grub, just save the changed menu.lst and that's it.

Of course, if you are dealing with grub it may be helpful reading the fine manual
