It used to be so simple - fdisk for MBR disks, gdisk et al for GPT.

Welcome to fdisk (util-linux 2.26.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

Modern fdisk now supports GPT. So yes, in this case the warning is
correct, but we need to watch out that people will be using fdisk, and
it's okay. Dunno when this happened, but I've only very recently noticed it.

Cheers,
