cfdisk is a curses-based disk partition table editor from the util-linux package. It provides a user-friendly text interface for creating, deleting, resizing, and changing the type of disk partitions, making it more approachable than the command-driven fdisk.
The tool supports both MBR (DOS) and GPT partition tables and displays partition layout in an interactive menu-driven format. Navigation uses arrow keys to select partitions and operations, with changes held in memory until explicitly written with the "Write" command.
The `-z` flag starts with a zeroed partition table, which is useful when setting up a new disk or switching between MBR and GPT schemes.

-z, --zero

Start with an empty partition table (useful for new disks)
