btrfs-inspect-internal: Print superblock's information.
$ sudo btrfs inspect-internal dump-super ${path-to-partition}
try on your machine

This command is used for inspecting the Btrfs (B-tree file system) superblock information of a specified partition. Let's break it down:

  • sudo: It is a command in Linux/Unix systems that allows users to run programs or commands with the security privileges of another user (commonly the superuser or root). By using sudo, the command will be executed as a privileged user, granting necessary permissions.

  • btrfs: It is the command-line tool for managing Btrfs file systems in Linux. Btrfs is a modern and feature-rich file system that provides functionalities like snapshots, compression, and advanced disk management.

  • inspect-internal dump-super: This part of the command refers to a specific operation within the btrfs tool. inspect-internal is a command that allows internal inspection of the Btrfs file system, while dump-super is a subcommand used to display the superblock information of the specified Btrfs partition.

  • ${path-to-partition}: This is a placeholder indicating that you need to replace it with the actual path to the Btrfs partition you want to inspect. The path could be something like /dev/sda1 or /dev/nvme0n1p2, depending on your system.

When you execute the command with the actual path to the partition, it will display detailed information about the Btrfs file system's superblock, including features, flags, UUIDs, and various other attributes specific to Btrfs.

This explanation was created by an AI. In most cases those are correct. But please always be careful and never run a command you are not sure if it is safe.
