What command would be used to list all partitions on a Linux system?

The command that is used to list all partitions on a Linux system is found at the path /proc/partitions. This file provides a summary of all block devices, including information about the major and minor device numbers, the number of blocks, and the device names, effectively giving you a comprehensive view of the partitions currently configured on the system.

In this context, /proc/partitions reads data directly from the kernel's virtual file system, which represents the system's state in real-time. This makes it a reliable source for identifying all the partitions available on a Linux system.

While other options mention commands related to logical volume management and storage initialization, they do not directly provide a list of partitions. The commands lvcreate and pvcreate pertain to creating logical volumes and initializing physical volumes, and /proc/mounts lists currently mounted file systems rather than showing all partitions on the system. Thus, /proc/partitions is the correct choice for obtaining a complete list of partitions on a Linux machine.
