Which command line tool is most often used for partitioning disks on Linux?

The command line tool most often used for partitioning disks on Linux is parted. This utility is versatile and designed for managing disk partitions in a more user-friendly way than some of the alternatives. Parted supports both MBR (Master Boot Record) and GPT (GUID Partition Table) partitioning schemes, making it suitable for modern systems. It provides a range of functionalities, such as creating, deleting, resizing, and moving partitions, and it can operate on disks with different types of partition tables.

While other tools such as fdisk and cfdisk are also used for partitioning, they are primarily focused on MBR and have limitations regarding GPT. Gparted, on the other hand, is a graphical interface for partition management but is not a command line tool. Parted stands out due to its command line capability and its robust feature set that supports both simplistic and complex partition management tasks efficiently.
