The command "sudo partx --list" is used for displaying partition information for a specific device or disk image. Here is an explanation of each part of the command:
-
"sudo": It is used to execute the command with administrative or superuser privileges. It allows the user to run the command as a different user, typically the root user, who has the necessary permissions to access system resources.
-
"partx": It is a command-line utility for creating, listing, and deleting partitions on a device or disk image. It helps to manage partition tables without requiring rebooting the system.
-
"--list": It is an option for the "partx" command, instructing it to list the partitions on the specified device or disk image.
-
"${path-to-device_or_disk_image}": It is a placeholder that represents the path to the device or disk image file for which you want to retrieve partition information. You need to replace "${path-to-device_or_disk_image}" with the actual path to the device or disk image file. For example, it could be something like "/dev/sda" for a device or "/path/to/disk/image.img" for a disk image file.
When you run the command with the specific path to a device or disk image, it will display a list of partitions along with their details, such as partition number, starting and ending sector, size, and filesystem type.
